SRS (Simple Realtime Server) is an open-source, high-performance real-time media server designed for building live streaming and real-time communication (RTC) services. It acts as a streaming gateway that ingests and delivers media across multiple protocols with an emphasis on low latency and efficiency.

Key Features

• Multi-protocol streaming support including RTMP, WebRTC, HLS, HTTP-FLV, SRT, MPEG-DASH, and GB28181
• Broad codec compatibility, including H.264, H.265/HEVC, AV1, VP9, AAC, Opus, and G.711
• Designed for high throughput and low-latency delivery for live streaming and RTC scenarios
• Docker-friendly deployments and support for cloud-native workflows
• Built-in observability support (commonly used with Prometheus exporters)

Use Cases

• Live streaming platforms that need RTMP ingest with HLS/HTTP-FLV/WebRTC playback
• Low-latency streaming for interactive events, gaming, and real-time broadcasts
• Video gateway services bridging traditional streaming protocols with WebRTC

Limitations and Considerations

• Primarily focused on media transport/gateway capabilities; a complete video platform typically requires additional components (players, authentication, recording/transcoding pipelines)

SRS is a strong fit when you need a reliable, efficient media server with broad protocol support and production-oriented performance characteristics. It is commonly used as a core building block in custom live streaming and WebRTC solutions.

Owncast is a free and open source live video streaming and web chat server that you run on your own infrastructure. It is designed for single-channel creators and works with common broadcasting tools by ingesting RTMP and delivering streams to viewers via the web.

Key Features

• RTMP ingest compatibility with popular broadcasters (for example, OBS and similar tools)
• HLS-based web playback with an integrated viewer page
• Built-in live chat, including support for custom emotes and community interaction
• Admin interface for stream configuration, moderation, and managing the viewer experience
• Optional Fediverse integration via ActivityPub so people can follow and share streams across compatible networks
• Embeddable player and chat components for integrating into other sites

Use Cases

• Run an independent live stream for a community, club, or small organization
• Host creator live streams without relying on centralized streaming platforms
• Add live video and chat to an existing website using embeds

Limitations and Considerations

• Primarily designed for a single streamer/channel rather than multi-tenant streaming platforms
• Does not natively support running as a Windows server (typically run on Linux; WSL2 may be used on Windows)

Owncast provides a straightforward way to control your live content, audience experience, and chat community from a server you manage. It is well-suited for creators who want a lightweight, independent alternative with familiar broadcasting workflows.

Janus WebRTC Server is a general-purpose WebRTC server (gateway) designed to establish and manage real-time media sessions with browsers and other WebRTC endpoints. It focuses on handling WebRTC signaling and media transport, while application logic is provided through a modular plugin architecture.

Key Features

• Pluggable server-side modules to implement features like echo tests, conferencing, recording, streaming, and SIP gatewaying
• JSON-based signaling and control API for interacting with plugins
• WebRTC media relay handling RTP/RTCP between peers and server-side components
• Optional API transports such as HTTP REST and WebSockets (build-time optional)
• Designed for a small footprint and deployment flexibility on Linux (and can be compiled on macOS)

Use Cases

• Building custom WebRTC conferencing, audio-bridge, or streaming applications
• Adding WebRTC access to SIP/VoIP infrastructures via gateway plugins
• Implementing media relays, recorders, and test utilities for real-time communications

Limitations and Considerations

• Functionality depends on plugins; the core server does not provide a full application by itself
• Windows is not officially supported (commonly run via Linux environments such as WSL)

Janus is best suited for developers and operators who need a high-performance WebRTC gateway with flexible, modular capabilities. Its plugin-based design makes it adaptable to many RTC architectures while keeping the core lightweight.

datarhei Restreamer is a self-hosted live streaming server that ingests video from sources like OBS or IP cameras, processes streams via FFmpeg, and publishes them to your website and/or external platforms. It combines a browser-based UI with streaming protocols and a documented API to manage inputs, outputs, and monitoring.

Key Features

• Ingest and publish using common streaming protocols (including RTMP, SRT, and HLS)
• Restream a single input to multiple outputs (e.g., social platforms or other streaming servers)
• Web-based setup wizard and streamlined administration interface
• Built-in embeddable web player and optional publication page
• FFmpeg-based transcoding and processing, including muxing separate audio
• Hardware-accelerated encoding support (e.g., NVIDIA CUDA), depending on deployment
• Bandwidth/viewer monitoring and optional limiting
• REST API with OpenAPI/Swagger documentation
• TLS automation with Let’s Encrypt for HTTPS (deployment-dependent)

Use Cases

• Publish a live stream to your own website while simultaneously restreaming to major platforms
• Centralize ingest from OBS and distribute to multiple RTMP/SRT endpoints
• Create a lightweight streaming gateway for events using commodity hardware (including SBCs)

Limitations and Considerations

• Reliable transcoding and multi-output restreaming can require significant CPU/GPU resources
• External publishing depends on the capabilities and limits of the destination platforms

Restreamer is a practical choice for organizations and creators that want to control their streaming stack while keeping setup approachable. Its UI-driven configuration, multi-protocol support, and API make it suitable for both simple live embeds and more advanced distribution workflows.

FreeSWITCH is an open-source, software-defined telecom stack used to build and run voice, video, and real-time communications infrastructure on commodity hardware. It is commonly used as a softswitch and media server for SIP-based telephony and can also provide browser-based calling via WebRTC.
