Devin
The first AI software engineer — autonomous end-to-end task completion.
7.6/10
Effortball score
Weighted across capability, reliability, ease of use, value and integrations.
What it does
Devin by Cognition is the most autonomous coding agent available. It has its own browser, shell, and code editor. Given a task, it plans, codes, tests, debugs, and iterates — largely without human intervention. Best for well-scoped feature requests.
Devin delivers on the "AI software engineer" promise for the right tasks. The autonomy is real but so is the price. Reliability still has rough edges — it can spiral on complex ambiguous tasks. Best used as a task-delegation layer for clear specs.
