Which one should I pick for a new project?

I can only help you understand the technical details of grvydev/project-lightspeed and ruvnet/ruview—the choice depends on your actual requirements.

Based on the repository data:

grvydev/project-lightspeed is a live streaming server that accepts streams from OBS via FTL protocol and delivers them to browsers via WebRTC, achieving sub-second latency. It has three main components: ingest, webrtc server, and frontend.

ruvnet/ruview is a WiFi-based spatial sensing system for detecting people, measuring vitals (breathing, heart rate), and tracking movement through walls—with smart-home integrations (Home Assistant, Apple Home, Google Home, Alexa).

These solve completely different problems:

• Lightspeed: Use if you need ultra-low-latency live video streaming
• RuView: Use if you need WiFi-based presence/health sensing and smart-home integration

Important caveat: According to RepoPilot analysis, grvydev/project-lightspeed shows a "WAIT — Stale" verdict with the last commit 3 years ago. This may indicate maintenance concerns; verify current viability before committing to it.

To give better guidance, describe what your project needs to accomplish.
