About Plandex
Plandex is a terminal-based AI coding agent for planning and executing large coding tasks across dozens of files. It loads relevant files, implements changes, runs terminal commands, and debugs builds and tests, keeping generated edits in a separate diff review sandbox until approved. It combines models from Anthropic, OpenAI, Google and open source providers using the user's own API keys. On Windows it runs only in WSL, not CMD or PowerShell, and Plandex Cloud was winding down as of 10/3/2025.
