Five tools. Local and free, your code never leaves your machine, no login.

Find it. Fix it. In seconds.

Agent memory

A .vibedrift/ folder your agent reads every session.

Live checks (MCP)

Your agent asks your codebase mid-task, answer in under a second.

Watch mode

Refreshes the memory on every save. Zero network calls.

Open source

Conventions the agent could already infer

≈ 0

No measurable change.

When the model would match your conventions anyway, the signal does nothing, and we're not hiding that.

Conventions it couldn't see or wouldn't pick

Cut by a statistically significant margin.
