Devin

The first 'fully autonomous software engineer' marketed at scale. Browser + shell + planning loop, fully cloud-hosted.

By C.W. Jameson · Published 19 May 2026 · Last reviewed 19 May 2026

Devin is the agent that put autonomous coding into mainstream investor conversation. Whether it actually does the job depends heavily on task framing — short bug fixes go well, long architecture tasks go badly. It remains the most-discussed and the most-controversial of the autonomous agents.
