owncast

Owncast is an open-source, self-hosted streaming platform that lets individuals run their own live video broadcasts and chat servers without relying on third-party platforms. It supports RTMP ingestion from standard broadcasting software like OBS and Streamlabs, with built-in moderation, federation via ActivityPub, and complete content ownership.

What owncast is

Owncast is a Go backend service with a React frontend that ingests RTMP streams, transcodes via ffmpeg, and serves HLS output to viewers. It includes built-in chat, ActivityPub federation for decentralized social features, and runs on Linux/WSL with no native Windows server support. Requires Go 1.24+, C compiler, and ffmpeg.

Quickstart

Get the owncast source

Clone the repository and explore it locally.

terminalbash

1git clone https://github.com/owncast/owncast.git2cd owncast3# follow the project's README for install & configuration

Best use cases

Independent Content Creator Broadcasting

Individuals, podcasters, or small media organizations seeking full control over stream infrastructure, branding, and audience data without platform censorship or algorithmic dependency.

Private/Internal Organization Streaming

Companies or communities wanting to host internal webinars, town halls, or training sessions on their own infrastructure with customizable chat and moderation policies.

Federated Social Video Communities

Projects building decentralized video networks where multiple Owncast instances can interact via ActivityPub, enabling distributed content sharing without central platform control.

Implementation considerations

Requires Linux server with Go 1.24+, C compiler (GCC/Musl), and ffmpeg. WSL2 is an option for Windows users but adds complexity.
RTMP ingestion is standard; ensure broadcaster software compatibility (OBS, Streamlabs, Restream tested) and firewall/port configuration for RTMP (default 1935) and HTTP (default 8080).
ActivityPub federation support enables cross-instance communication; verify federation requirements align with deployment goals if decentralization is a priority.
No documented horizontal scaling or clustering; single instance architecture means capacity planning must account for concurrent viewer limits and transcoding CPU demand.
Develop branch is unstable; production deployments should use released tags (e.g., v0.2.5) and plan upgrade testing to avoid stream disruptions.

When to avoid it — and what to weigh

Requires Windows Native Server Support — If production deployment requires native Windows Server, Owncast is not suitable. WSL2 is available but adds operational complexity and is not production-grade Windows support.
Multi-Tenant SaaS Service — Owncast is designed for single-user, self-hosted instances. It is not architected for multi-tenant SaaS platforms where you manage multiple users' streams and billing.
Minimal Operational Experience — Deployment requires managing Go services, ffmpeg, networking, and Linux administration. Organizations lacking DevOps capability should expect significant setup and maintenance burden.
Enterprise High-Availability Streaming — Owncast lacks documented redundancy, failover, or clustering for mission-critical, high-concurrency streaming. Not suitable for broadcast operations requiring SLAs or automatic recovery.

License & commercial use

Security considerations

No security audit, CVE history, or threat model documented in provided data. RTMP stream ingestion and chat moderation are core features; review authentication, authorization, and input validation for moderation rules. Self-hosted model shifts responsibility to operator for network hardening, SSL/TLS setup, access control, and data privacy. ActivityPub federation may expose instance metadata; verify federation privacy requirements. ffmpeg processing of untrusted streams poses transcode-related risks; keep ffmpeg and dependencies patched.

Alternatives to consider

Nextcloud Talk / Spreed

Self-hosted video platform with built-in federation; more mature for conferencing but less optimized for single-direction live streaming and audience chat at scale.

Vimeo Live (on-premise) / Wowza Streaming Engine

Enterprise-grade, closed-source streaming platforms with professional support, clustering, and SLA; higher cost and proprietary, but production-ready HA and monitoring.

PeerTube

Federated video platform similar philosophy; focuses on VOD and archival over live streaming, and higher storage/indexing overhead; strong federation but less optimized for real-time live broadcast.

owncast FAQ

Can I run Owncast on Windows?

Not natively. Windows users can use Windows Subsystem for Linux 2 (WSL2) to run Owncast, but this is not production-grade Windows Server support and adds operational complexity.

Does Owncast support multi-user or multi-stream?

No. Owncast is designed as a single-user, single-instance service. Each instance runs one stream; to host multiple users, you must run separate Owncast instances.

What broadcasting software is compatible?

Any software supporting RTMP ingestion, including OBS, Streamlabs, Restream, and others. Point your RTMP output to your Owncast instance (default RTMP port 1935).

Is there commercial support or a managed hosting option?

No vendor-managed hosting or commercial support contracts documented. Project is community-driven and funded by OpenCollective donations. Commercial customization or support requires private arrangement.
