Introduction - High-Performance Rust Streaming Server Monibuca

What is Monibuca?

Monibuca (abbreviated as m7s) is a high-performance streaming media server engine. Version 6 has been completely rewritten from scratch in Rust, pushing performance to the extreme while maintaining a flexible plugin-based architecture.

Monibuca is a commercial, closed-source product: deploy via official pre-built downloads or Docker images. Public source code and building the engine yourself are not offered. The Free edition runs without a time limit (Editions & Licensing); Professional and Enterprise tiers require a license.

Monibuca is not just a streaming server — it is an engine. It provides comprehensive streaming media processing capabilities, allowing developers to rapidly build streaming applications tailored to various business requirements through its plugin system.

Core Features

Multi-Protocol Support

Monibuca natively supports mainstream streaming protocols, ready to use out of the box:

Protocol	Publish	Subscribe	Description
RTMP	✅	✅	Classic low-latency publishing protocol
RTSP	✅	✅	Commonly used for surveillance devices
HTTP-FLV	-	✅	HTTP long-connection streaming
HLS	-	✅	Widely compatible segmented protocol
WebRTC	✅	✅	Based on WHIP/WHEP standards, ultra-low latency
SRT	✅	✅	Secure Reliable Transport protocol
GB28181	✅	✅	Chinese national standard for video surveillance networking
WebTransport	✅	✅	Next-generation transport protocol based on QUIC

Zero-Copy RingBuffer

Featuring a proprietary zero-copy ring buffer design, audio and video data written by publishers is read directly by all subscribers through references without memory copying. This design results in extremely low memory overhead when a single stream serves a large number of concurrent subscribers.

Dispatcher Architecture

An event-driven architecture based on the Dispatcher enables efficient stream management and distribution. Each stream has its own Dispatcher instance responsible for coordinating data flow between publishers and subscribers.

Plugin System

All protocols and features are implemented as plugins. Official pre-built binaries include every built-in plugin; enable or disable them in configuration. Dynamic loading of third-party .so / .dylib plugins is also supported at runtime.

Cluster Support

Built-in cluster plugin supporting multi-node deployment and cross-node stream distribution, easily handling large-scale concurrent scenarios.

Full-Stack Monitoring & Operations Dashboard

V6 includes a complete monitoring system spanning from stream-level to site-wide, with no third-party tools required:

• Stream-level real-time monitoring: Per-frame waveforms + bitrate/framerate/GOP trend charts with live SSE push
• Room-level quality analysis: Sender-receiver pair analysis with bitrate, freeze, packet loss, and resolution comparison
• Live operations dashboard: Site-wide real-time overview, 7-day trends, popularity ranking, risk detection
• Three-tier reporting: Heartbeat (real-time quality) + Leave (session snapshot) + KV (event counters)

Through the Admin dashboard, operations teams can monitor site-wide live streaming status in real time, while developers can quickly diagnose audio/video quality issues through bitrate and framerate analysis. See Monitoring & Operations for details.

V6: Complete Rust Rewrite

V6 is a milestone release for Monibuca, fully migrated from Go to Rust, bringing a quantum leap in capabilities:

• Extreme performance: Rust’s zero-cost abstractions and memory safety guarantees deliver significantly higher throughput
• Memory safety: Data races and memory leaks are eliminated at compile time, ensuring stable server operation
• Lower latency: No GC pauses, making audio/video processing latency more predictable
• Full-stack monitoring: Built-in three-tier reporting + three dashboards, real-time observability for bitrate/framerate/freeze
• Full-stack ecosystem: Engine + Admin dashboard + monitoring dashboards + Web player + Web SDK, all developed in-house
