About Devon
Devon is an open-source pair programmer that works inside a project folder to edit multiple files, explore the codebase, write configs and tests, and fix bugs. It runs through a main UI or a terminal interface and requires an Anthropic, OpenAI, or Groq API key.
It is focused on Python, with minimal functionality for other languages, and local model use is described as not mature. Windows support was listed as in progress.
