The 10 Best Free RTMP Server Options for 2026

You've got OBS open, your camera feed looks good, audio is clean, and the stream key is waiting. Then you hit the part that stops a lot of otherwise solid live setups. You still need the server layer that accepts RTMP, keeps the ingest stable, and turns that feed into something viewers can watch.

That's where picking a free RTMP server gets messy. Some options are tiny and reliable if all you need is RTMP ingest plus HLS output. Others are closer to full media platforms with WebRTC, protocol bridging, transcoding, and admin panels. The software may be free, but the actual trade-offs show up in setup time, operational complexity, security, and how much hand-holding the stack gives you once traffic starts climbing.

A good rule is simple. If you want a lab setup or a lightweight production origin, start small. If you expect multiple protocols, browser playback options, or low-latency delivery beyond classic RTMP, choose a server that can grow with you. That hosting decision matters too, because in real deployments the license cost is often less important than server capacity, bandwidth, and transcoding headroom. If you're still deciding where this should run, this ARPHost dedicated vs VPS analysis is a good practical companion.

One more reality check before the list. A “free RTMP server” usually isn't a separate product category. It's more often an open-source stack, self-hosted deployment, or community edition built around RTMP ingest. RTMP became a foundational live streaming protocol because it gives encoders like OBS a low-latency, persistent TCP-based path into a media server, which is why it still shows up so often in first-mile workflows, as outlined in this RTMP server overview from Callaba.

1. Nginx with nginx-rtmp-module

A common real-world setup starts like this. OBS needs a stable RTMP endpoint, viewers can live with HLS latency, and nobody wants to deploy a full media platform just to get a stream online. Nginx with nginx-rtmp-module still fits that job well.

It is plain, predictable, and easy to inspect. You edit config, reload the service, and know exactly where ingest and segment output are happening. That makes it a strong first choice for a free RTMP server if your goal is an origin server, not an all-in-one streaming product.

Quickstart

A typical Ubuntu install uses the distro package and a small rtmp block:

sudo apt update
sudo apt install nginx libnginx-mod-rtmp -y

rtmp {
    server {
        listen 1935;
        application live {
            live on;
            record off;
            hls on;
            hls_path /var/www/html/hls;
            dash on;
            dash_path /var/www/html/dash;
        }
    }
}

Use OBS with rtmp://YOUR_SERVER_IP/live as the server URL and your chosen stream key as the stream name.

Recommended use case

Choose this stack for a DIY ingest origin, internal broadcasts, event streaming, or a small production workflow where RTMP ingest plus HLS or DASH output is enough. It also works well in environments where the team already manages Nginx for web traffic and prefers config files over dashboards.

The trade-off is operational convenience. Nginx RTMP stays out of your way, but it also gives you less built-in help with modern playback protocols, clustering, and day-two admin tasks. If your deployment process already depends on repeatable automation, the difference between config-driven services and orchestration tools starts to matter. Teams comparing those approaches usually run into the same questions covered in this Jenkins vs Ansible deployment workflow comparison. Teams building adjacent publishing or delivery tooling often pair this kind of setup with broader app workflows like those in web dev apps.

Performance and security notes

In production, this server does best when you keep the role narrow. Accept RTMP ingest, write HLS or DASH segments to fast local storage, and put a CDN or separate web tier in front of playback if audience size grows. If you need heavy transcoding, add FFmpeg as a separate process rather than expecting the module to become a media pipeline by itself.

Security needs attention early.

Practical rule: Add publish authentication before the box is public. An on_publish callback or tightly controlled stream keys should be part of the first deployment, not a cleanup task later.

The other limitation is secure ingest. Native RTMPS support is not the main reason people use this module, so many deployments terminate TLS elsewhere or place Nginx RTMP behind another edge layer. That is acceptable in controlled infrastructure and lab environments. It is less attractive if you want modern transport security and multi-protocol delivery from a single server.

• Best at: Lightweight RTMP ingest and basic HLS or DASH output
• Watch out for: Extra work for secure ingest, transcoding, and long-term feature growth
• Website: nginx-rtmp-module on GitHub

2. SRS (Simple Realtime Server)

SRS is what I recommend when someone starts by saying they need RTMP today, but I know they'll ask for WebRTC, SRT, or lower-latency browser playback later. It handles the “free RTMP server” role well, but it doesn't trap you in an RTMP-only mindset.

That matters. A lot of teams don't want RTMP as the viewer protocol anymore. They want RTMP ingest because OBS supports it well, then they want modern playback paths downstream.

Quickstart

The exact install path varies by package or container choice, but the shape is simple. Enable RTMP ingest, turn on the HTTP server, and enable HLS in the default vhost.

listen 1935;
http_server {
 enabled on;
 listen 8080;
}
vhost __defaultVhost__ {
 hls on;
 hls_path ./objs/nginx/html;
}

Then publish from OBS or FFmpeg to your live app and serve playback from the built-in HTTP side.

Recommended use case

Choose SRS if you want one server that can start as an RTMP ingest endpoint and later become the center of a broader real-time stack. It's a strong fit for product teams, internal platforms, and startups that don't want to replatform as requirements expand.

It's also a better long-term choice than minimal RTMP-only tooling when your ops team values consistency. If you already think in terms of repeatable deploys, config management, and service orchestration, the mindset is similar to other infrastructure-heavy choices discussed in Jenkins vs Ansible.

Performance and security notes

SRS gives you more room to grow, but that flexibility comes with more config surface. New users sometimes overbuild on day one. Don't. Start with RTMP ingest and one playback format, then add protocols only when you have an actual delivery need.

SRS is the server I'd choose when the requirement is likely to change in six months.

Its real advantage is optionality. You don't have to switch stacks just because RTMP stops being enough for viewer delivery.

• Best at: Multi-protocol growth beyond plain RTMP
• Watch out for: More knobs, more ways to misconfigure things
• Website: SRS official site

3. OvenMediaEngine (OME)

A common setup goes like this. OBS or a hardware encoder sends RTMP without trouble, then the product team asks for browser playback with lower delay than standard HLS can usually provide. OvenMediaEngine fits that job well because it treats RTMP as ingest and focuses its real effort on viewer delivery through WebRTC and LL-HLS.

That makes OME a better match for interactive products than for a plain archive or one-way webinar origin. If the stream needs chat-driven responses, near-real-time bidding, classroom interaction, or live commerce timing that feels tight, OME is worth the extra operational work.

Quickstart

The fastest way to test it is with Docker, then add an application config for your publish path and playback outputs.

docker run -d --name ome \
  -p 1935:1935 -p 3333:3333 -p 8081:8081 \
  airensoft/ovenmediaengine:latest

After the container is up, point OBS at the RTMP publish endpoint you define in OME and verify playback through the delivery method you plan to ship, usually WebRTC first and LL-HLS second.

Recommended use case

Choose OME when the viewer experience matters more than keeping the media stack minimal. It works well for teams that already have stable RTMP encoders but need faster playback in browsers without building a custom relay layer themselves.

I would also consider it for product teams that want a dedicated media service instead of burying streaming logic inside the main app. That service boundary is similar to the trade-offs teams weigh when choosing a backend as a service provider. You gain speed and clearer ownership, but you also take on a separate system that needs tuning and monitoring.

Performance and security notes

OME rewards deliberate setup. CPU usage, network behavior, and port exposure matter more here than with a simple RTMP origin because low-latency delivery paths are less forgiving of bad defaults.

Treat RTMP as first-mile transport only. Publish in, transcode or package as needed, and deliver in a protocol meant for modern playback. That pattern is common in real deployments because browser-facing latency targets and compatibility needs are different from encoder-side ingest needs.

Observability also matters early, not later. Watch connection counts, transcoding load, and packet loss before you put real traffic on it. The teams that struggle with OME are usually not blocked by RTMP itself. They get caught by under-sized hosts, incomplete TURN or firewall planning for WebRTC, or exposing more listening ports than the deployment needs.

• Best at: RTMP ingest paired with low-latency browser delivery
• Watch out for: Higher setup and ops overhead than a basic streaming origin
• Website: OvenMediaEngine official site

4. MediaMTX (formerly rtsp-simple-server)

MediaMTX is the tool I reach for when the requirement sounds messy. One camera speaks RTSP, another source wants SRT, OBS needs RTMP, and the browser team wants WebRTC or LL-HLS. That kind of protocol glue job is where MediaMTX shines.

It's deceptively simple because the project ships as a lightweight single binary, but it's far more useful than its footprint suggests. For a free RTMP server, it's one of the easiest ways to turn protocol conversion into a manageable service instead of a hand-built pile of scripts.

Quickstart

Run the binary or container, then edit the YAML config only where needed.

docker run --rm -it \
  -p 1935:1935 -p 8554:8554 -p 8888:8888 \
  bluenviron/mediamtx:latest

By default, you can publish to an RTMP path once the service is up, then expose alternate read protocols depending on the config you enable.

Recommended use case

Use MediaMTX when simplicity matters but your protocol needs don't. It's great as a gateway, edge bridge, camera aggregation point, or small media hub that needs to stay lean.

It's especially useful in mixed environments where one service shouldn't become a giant media platform. For backend teams that think in terms of standalone services and clean interfaces, it fits the same practical mindset behind backend as a service provider decisions.

Performance and security notes

MediaMTX is easy to launch, which makes it easy to expose carelessly. Lock down publish permissions, trim unused protocols, and keep external exposure narrow. A small binary doesn't mean a small blast radius.

The best MediaMTX deployments are opinionated. Turn on only the protocols you actually need.

Its main tradeoff is ecosystem depth. You get speed and clarity, but not the same volume of old tutorials, third-party snippets, and battle-scarred community docs you'd find around Nginx or Red5.

• Best at: Protocol conversion with low overhead
• Watch out for: Fewer built-in workflow extras than larger platforms
• Website: MediaMTX on GitHub

5. Ant Media Server Community Edition

A common setup looks like this: a small team needs RTMP ingest working today, OBS users need clear publishing steps, and nobody wants the first week consumed by hand-built configs. Ant Media Server Community Edition fits that job well. It feels like an application you operate, not just a media process you babysit.

That changes who can own the system. A developer can install it, but day-to-day tasks like creating apps, checking stream status, and handling basic publishing flow are easier to hand to a product or ops teammate through the web UI.

Quickstart

A practical first pass is to install Ant Media, open the management panel, create an application, and publish a test stream from OBS or FFmpeg to the RTMP endpoint.

ffmpeg -re -i input.mp4 -c:v libx264 -c:a aac -f flv rtmp://SERVER/LiveApp/streamKey

In real deployments, this section matters because teams can validate ingest fast, then decide whether they need more automation around provisioning, app creation, or player-side workflows. If that wider system will coordinate media actions with other services, it helps to understand different types of API calls before wiring the platform into the rest of the stack.

Recommended use case

Choose Ant Media Community Edition when you want GUI-first administration, quick onboarding for stream operators, and a cleaner path to a working RTMP service than Nginx-based builds usually provide.

It is a good fit for internal streaming tools, early product prototypes, small event platforms, and teams that expect non-infrastructure staff to touch the media layer. I would also consider it when the question is less "what is the lightest daemon?" and more "what can this team run reliably without building extra control tooling first?"

Performance and security notes

The practical upside is operational clarity. RTMP ingest is familiar, the app model is easy to explain, and initial setup tends to be faster than stitching together multiple components yourself.

The trade-off is headroom and control. Community Edition is useful, but it is not the full commercial platform, so teams with larger concurrency targets, stricter scaling plans, or advanced workflow requirements often outgrow it. Security also deserves attention early. Restrict management access, protect publish paths, and avoid exposing the admin panel broadly just because setup was easy.

• Best at: Fast RTMP onboarding with a usable admin interface
• Watch out for: Community Edition limits as workflows or scale become more demanding
• Website: Ant Media Server official site

6. Red5 (Open-Source)

Red5 is the veteran in the room. If your environment still cares about traditional RTMP and RTMPS compatibility, or your team is comfortable in Java-heavy infrastructure, Red5 can still make sense. It has the feel of an older media server because it is one, but that isn't automatically a drawback.

Some stacks need stable legacy behavior more than they need trendy protocol breadth. Red5 serves that audience better than tools designed first around modern browser-native delivery.

Quickstart

A minimal path is to deploy Red5, enable the live application, open the ingest port, and publish from OBS or FFmpeg.

ffmpeg -re -i input.mp4 -c:v libx264 -c:a aac -f flv rtmp://SERVER/live/stream

For browser playback, many teams pair it with FFmpeg or another helper to transmux into HLS instead of asking viewers to consume RTMP directly.

Recommended use case

Choose Red5 when RTMP or RTMPS compatibility is the main requirement, especially in Java shops or legacy streaming environments. It's also reasonable when an older system already assumes Red5 semantics and changing the media layer would create more risk than value.

Performance and security notes

Red5's strength is familiarity for the right audience. Its weakness is that it doesn't lead with modern viewer delivery patterns. If you need WebRTC, LL-HLS, or aggressive protocol bridging, other tools on this list will feel more current.

That doesn't make Red5 obsolete. It makes it specific. When teams know they need a classic RTMP-focused stack, specificity is useful.

• Best at: Legacy RTMP and RTMPS workflows
• Watch out for: Extra components for modern browser delivery
• Website: Red5 official site

7. MistServer Open Source Edition

MistServer Open Source Edition sits in a useful middle ground. It's more polished than the most barebones options, but it doesn't try to be everything at once. For a free RTMP server, that can be refreshing.

I like MistServer most for prototyping media workflows that may later move into a more feature-rich commercial setup. You can get streams moving without committing to a giant operational surface area, then decide later whether the paid path is justified.

Quickstart

A typical start is to install the open-source edition, launch the service, create a live stream, and publish RTMP into the named application.

ffmpeg -re -i input.mp4 -c:v libx264 -c:a aac -f flv rtmp://SERVER/live/stream

Playback and additional delivery behavior depend on how you configure the stream and what edition features you're using.

Recommended use case

Use MistServer OSS for prototypes, labs, and small deployments where you want a cleaner product feel than raw config files but don't yet need a media platform that offers extensive customization. It's also a decent stepping stone if you suspect commercial features may matter later.

Performance and security notes

MistServer's open-source path is practical, but you need to be clear-eyed about edition limits. If your plan depends on advanced multibitrate behavior or broader protocol options, confirm early whether that belongs to the free experience or the paid path.

Don't choose MistServer OSS because you hope missing features will somehow appear later in the same edition. Choose it because the current open-source feature set already matches your launch needs.

For teams with disciplined scope, it can be a solid way to launch without overengineering.

• Best at: Clean prototyping with a commercial upgrade path
• Watch out for: Open-source limits on advanced delivery workflows
• Website: MistServer Open Source Edition

8. Node-Media-Server (NMS)

Node-Media-Server makes a lot of sense if your team already lives in JavaScript or TypeScript and wants to embed media logic close to the app layer. It's not the first server I'd pick for the most demanding production edge, but it is one of the fastest ways to get an RTMP ingest service running inside a Node-centric stack.

That's the appeal. You can keep custom auth, hooks, metadata handling, and app behavior in a language your team already uses daily.

Quickstart

Install the package, define the RTMP block, and start the process.

npm install node-media-server

const NodeMediaServer = require('node-media-server');

const config = {
  rtmp: {
    port: 1935
  }
};

new NodeMediaServer(config).run();

From there, publish from OBS to the configured RTMP endpoint and use FFmpeg when you need HLS or DASH packaging.

Recommended use case

This one fits prototypes, internal tools, and custom products where media ingest is part of a broader Node backend rather than an isolated infrastructure service. It's also useful when you want code-centric extensibility more than turnkey media operations.

Performance and security notes

NMS is flexible, but it leans on FFmpeg for a lot of practical processing and packaging work. That's not bad. It just means the full solution is often “Node-Media-Server plus FFmpeg plus your app logic,” not a single self-contained media platform.

If you're pushing toward heavier production use, test your operational model carefully. The more custom logic you pack into the same Node runtime, the more discipline you'll need around isolation, restarts, and resource contention.

• Best at: JavaScript-native streaming prototypes and custom logic
• Watch out for: Less battle-tested for demanding high-scale media workloads
• Website: Node-Media-Server on GitHub

9. Nimble Streamer (Softvelum)

Nimble Streamer is the option I think of as “free to start, professional in temperament.” The core server is free, but the broader experience often points you toward paid control and transcoding components if you want a smoother operational life.

That doesn't make it a bad free RTMP server. It makes it honest about where the free layer ends and where commercial convenience begins.

Quickstart

A common pattern is to install Nimble, create an application in the management layer you're using, then publish RTMP to the configured app path.

ffmpeg -re -i input.mp4 -c:v libx264 -c:a aac -f flv rtmp://SERVER:1935/live/stream

Viewer playback is usually exposed through HLS, DASH, or other enabled protocols depending on the setup.

Recommended use case

Choose Nimble when you want a production-minded engine with a free entry point, especially if you're comfortable with the idea that management, transcoding, or richer operations may eventually move into paid modules. It's a good fit for teams that want something more polished than community-only tooling without going all-in on a closed commercial stack on day one.

Performance and security notes

Nimble has a strong reputation among operators who care about efficiency and reliability. The catch is that the “best version” of the workflow often involves surrounding products like WMSPanel or the transcoder.

That's fine if you plan for it. It's frustrating if you thought the free core alone would cover every production need forever.

• Best at: Efficient production deployments with room to extend commercially
• Watch out for: Key workflow improvements may sit in paid add-ons
• Website: Nimble Streamer official site

10. Owncast

A common real-world problem looks like this. The stream itself is easy to publish from OBS, but the viewer page, chat, and basic broadcast workflow still need to be built around it. Owncast solves that packaging problem. You send it RTMP, and it gives you a self-hosted viewing destination with chat and an admin layer that is already wired together.

That changes the buying criteria. Owncast is less about serving as a general media plumbing tool and more about getting a small live operation on air quickly with fewer moving parts.

Quickstart

The fastest path is Docker. Start the container, open the admin area, set your stream key, and publish from OBS or FFmpeg to the RTMP ingest endpoint.

docker run -d --name owncast \
  -p 8080:8080 -p 1935:1935 \
  owncast/owncast:latest

After that, you already have a player page and chat. No separate frontend assembly required.

Recommended use case

Pick Owncast for creator-led channels, community streams, internal town halls, classes, and small events where the destination experience matters as much as the ingest server. It is a good fit for teams that want one box to handle publishing and audience viewing without stitching together a player, auth flow, and chat stack from scratch.

Performance and security notes

Owncast works best inside a straightforward workflow. RTMP comes in from OBS or another encoder. Viewers watch through browser-friendly delivery handled by the platform. That keeps setup simple, but it also means Owncast is not the right tool if your main requirement is protocol conversion, edge relay design, or a larger multi-service media fabric.

In practice, this is a good server to choose when the stream site is the product. It is a weaker choice when the server needs to act like infrastructure for many downstream systems.

Plan capacity carefully. Viewer delivery can become the bottleneck before RTMP ingest does, especially on a single VM with limited CPU and outbound bandwidth. For security, treat the admin interface like any other public control plane. Put it behind HTTPS, use a strong stream key, keep the container updated, and avoid exposing management endpoints more broadly than necessary.

• Best at: Self-hosted live streaming with built-in viewer page and chat
• Watch out for: Less suited to custom protocol workflows or large routing topologies
• Website: Owncast official site

Your Stream Is Live. What's Next?

Once your free RTMP server is running, the hardest part is usually over. You've established ingest, validated your encoder settings, opened the right ports, and proved that video can move from source to viewers without relying on a hosted platform for every layer. That's a meaningful milestone, especially if you're building your own product or internal streaming capability.

The next decision is less about “which server is best” and more about whether your current stack matches the specific task. If your priority is simple RTMP ingest with HLS playback, Nginx with nginx-rtmp-module still makes sense. If you need room for WebRTC, SRT, or protocol expansion, SRS or MediaMTX usually age better. If low-latency browser delivery is the actual requirement, OvenMediaEngine is closer to the target. If you want a GUI and easier onboarding, Ant Media Community Edition is more approachable. If you want an all-in-one destination instead of media plumbing, Owncast is the easiest recommendation.

A lot of teams learn the same lesson after launch. Free software doesn't mean free operations. RTMP servers usually run on general-purpose cloud or data center infrastructure, so the cost and stability conversation quickly shifts toward compute, storage, bandwidth, and transcoding headroom. That's especially true if you ingest RTMP and then repackage into HLS, WebRTC, or CMAF for playback. Independent server market forecasts place the global server market at USD 111.60 billion in 2023 and project it to reach USD 224.90 billion by 2032 at an 8.14% CAGR, while another forecast projects USD 1,027.83 billion by 2033 with a 14.8% CAGR, according to this server market forecast from SNS Insider. You don't need those projections to run a stream, but they reinforce the operational reality. Infrastructure choice matters.

Security also stops being optional as soon as the server is public. Use auth for publish, restrict unnecessary protocols, protect admin endpoints, and decide early whether you need RTMPS, reverse proxy termination, or private network ingress. In small setups, people often postpone this work because the stream is “just temporary.” Temporary systems have a habit of becoming production.

After that, focus on packaging your work into something people can use. If this RTMP stack supports a SaaS product, creator tool, internal platform, or media workflow service, the technical backend is only half the job. You still need distribution, discovery, and early users who can validate whether the product solves a real problem.

That's the part many builders underestimate. Launching the infrastructure is satisfying. Launching the product around it is what creates momentum.
