Devin

Key facts: Devin, from Cognition, is an autonomous AI software engineer: give it a task in a repository and it plans the work, writes and tests code, fixes its own errors and opens a pull request, working in its own cloud workspace while you review progress.

Plans: Devin is a paid product with usage-based pricing and team plans; check the official pricing page, as autonomous agent runs are billed by usage rather than a flat seat price.

Best for: engineering teams with well-specified backlogs, migrations and bug-fixing work. Watch out: autonomous does not mean unsupervised — review its pull requests like any junior engineer’s, especially on security-sensitive code. Who should skip it: teams with vague, unscoped tasks and no reviewer available to check pull requests.
