io.unom.Punktfunk CC0-1.0 MIT OR Apache-2.0 Punktfunk

Low-latency desktop and game streaming client

Punktfunk is the native Linux client for the punktfunk low-latency desktop and game streaming stack. It discovers hosts on the LAN over mDNS, trusts them via certificate pinning with a SPAKE2 PIN pairing ceremony, and streams HEVC video (GF(2^16) Leopard FEC plus AES-GCM over UDP, with a QUIC control plane) at exactly the requested resolution and refresh rate — no scaling.

Features:

Hardware-accelerated HEVC decode (VAAPI zero-copy on AMD and Intel, software fallback)
PipeWire audio playback and microphone uplink
Full gamepad support including DualSense touchpad, motion, adaptive triggers and lightbar (SDL3)
LAN host discovery, TOFU fingerprint pinning and PIN pairing
