Maintained by plandex-ai, an independent project by Dane Schneider.

A terminal coding agent that plans and applies changes across large multi-file projects with diff review.

Runs as a CLI against a local or self-hosted server; changes stage in a sandbox before applying.

Reach for it when tasks span many files and you want reviewable, staged edits.

A version-controlled sandbox and cumulative diffs make big AI-driven changes safer to review.

An LLM API key (OpenAI, Anthropic, and others) and the Plandex server.

Small team, open-source; the agent writes files and runs commands behind an explicit apply step. MIT licensed, actively developed.
