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.

RunRecount
Runs, hikes, and walks from Apple Health, in one iPhone app.
RunRecount reads your runs, hikes, and walks 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.
