Five fast-rising GitHub projects focus on agent infrastructure:

niubigeo: open-source, self-hosted GEO tool that shows how AI models describe your product, competitors, and sources per domain; 1,307 stars in a day (10.2k total), pitched as a free alternative to $5k/year black-box services.
vercel-labs/agent-browser: Rust-native browser CLI that compresses pages into numbered accessibility-tree text; agents click refs and re-read to verify, erroring when elements are occluded instead of guessing from screenshots; 812 stars/day.
Concat: free, local-first cross-platform video editor with auto-subtitles, TTS, background removal, multi-track and 4K export, scriptable via JSON-RPC and MCP; 491 stars/day.
billion-context: context-compression plugin for coding agents claiming 5x token savings, month-long sessions at billions of cumulative tokens, 95–97% prefix-cache hit rate, backed by a paper from 4.5 months and 170k production calls.
