# What is Devon?

Devon (not to be confused with Devin) is an open-source autonomous AI software engineer that can handle multi-step engineering tasks in a sandboxed environment. It runs commands, edits files, and validates its own output with a test loop.

Who is it for? Developers and teams who want to delegate multi-step coding tasks to an autonomous agent.
