- lineage
- YC S26 coding agent built by Yale CS grads (ex-AppLovin/Citadel); own router, tools, and agent loop shared between a CLI (npm @trybullet/cli) and a Mac desktop app, positioned around latency: auto-picks model/reasoning tier per prompt, parallelizes searches/reads/commands, and uses targeted code search instead of full-repo embedding
- note
- Works with a user's own Claude Code or Codex subscription, API keys, or an on-device model for the underlying model calls; free to use, no open-source license found; distinct from tracked speed/latency-focused terminal agents (Factory Droid, Warp) on its per-prompt routing pitch
