libpeer is a portable WebRTC implementation written in C using BSD sockets, designed for IoT and embedded devices such as ESP32 and Raspberry Pi. It supports H264 and G.711/OPUS codecs, DataChannel, STUN/TURN, IPv4/IPv6, and WHIP or MQTT signaling.

Use cases

• stream video from an ESP32 camera to a browser via WebRTC
• add two-way audio and video streaming to a Raspberry Pi project
• send MJPEG frames over a WebRTC datachannel from a microcontroller
• implement peer-to-peer media streaming on embedded Linux devices
• use WHIP signaling to publish media from an IoT device
• run WebRTC datachannel ping-pong on a Raspberry Pi Pico

When to choose

• you need WebRTC on resource-constrained embedded hardware like ESP32
• you want a lightweight C library without a full browser stack
• you need H264 or G.711/OPUS streaming from IoT devices to browsers
• you prefer MQTT or WHIP signaling on embedded platforms

When to avoid

• you need a full-featured WebRTC stack with broad codec and browser compatibility
• you are building a desktop or server application where libwebrtc or aiortc fits better
• you need extensive documentation and enterprise support
• your project requires JavaScript or Python rather than C integration
