All projects →agentcam
A dashcam for your coding agents.
agentcam reads the session logs Claude Code and Codex already write and shows what your agents did: step-by-step replays, full-text search, which agent-written lines are still in the code, and a risk audit. One local Rust binary with an embedded React UI. Nothing leaves your machine.

Orion
A running app for iOS, built on Apple Health.
Orion reads your runs straight from HealthKit and turns them into routes, splits, streaks, records, and training analytics — VO₂max trends, training load, heart rate zones, cadence, and a map that renders where you run as a heat corridor. Everything is computed and stored on the device.
