Devin

Also known as: Cognition Devin, Cognition AI Devin

The first widely-publicized commercial AI software engineer, from Cognition AI. Devin can handle end-to-end software tasks: reading requirements, writing code, running tests, debugging, and deploying, with minimal human intervention.

Devin created a category when it launched in 2024. It wasn't just a code completion tool: Cognition positioned it as an AI colleague who could own an entire engineering task from spec to deployment. Devin has its own shell, browser, and code editor, and can work through multi-hour engineering jobs autonomously, checking in with humans when it's stuck.

Devin's release preceded a wave of competing products: OpenHands (the open-source alternative), Claude Code, Jules from Google, and Codex from OpenAI all followed. The comparison benchmark is SWE-bench, and Devin's scores have been surpassed by multiple open-source alternatives. But Devin remains relevant as the commercial product that defined what the category could look like.

The main critique of Devin has been cost and reliability: fully autonomous software engineering on complex codebases fails more than it succeeds, and the token costs can be high. The more common deployment pattern in 2025 is using Devin-like agents for bounded, well-specified tasks rather than open-ended development.
