What is it?

Monibuca is a streaming server framework written in Go, designed so that functionality is loaded as plugins on demand. It handles ingest and distribution of live streams across protocols including RTMP, RTSP, HTTP-FLV, WS-FLV, HLS, WebRTC, SRT, GB28181 and ONVIF.

Beyond live forwarding, it provides recording to MP4, HLS and FLV, time-shift playback through a dynamic cache, screenshots, transcoding, stream aliases, and stream authentication. Cluster features include cascade relaying and room management, and a gRPC interface allows integration from other languages. WebHook callbacks report stream lifecycle events to business systems.

The project includes a Web UI served from an admin.zip file, Prometheus metrics at /api/metrics, and a build-tag system for choosing database backends such as SQLite, MySQL, PostgreSQL or DuckDB. Plugins can be developed to extend it, and the project is licensed under AGPL-3.0.

Key features

  • 01Plugin-based architecture where features are loaded on demand

  • 04Live time-shift playback through a dynamic cache
  • 05Built-in gRPC interface, WebHook events and Prometheus metrics

Use cases

  • Building a custom live streaming platform or video surveillance backend
  • Relaying and distributing RTSP or RTMP camera streams to browsers over HLS or WebRTC
  • Recording live streams to MP4 or HLS for later playback
