In their own words
Devin
Devin is a coding tool that Cognition describes as an autonomous software engineer: it can plan, write, test and ship production code. Its workflows include migrations, refactors, documentation, scheduled chores, issue triage, bug fixes, testing and performance optimization. Devin runs in the cloud or on a user's machine, tests in its own browser and works toward a pull request ready to merge; larger tasks can be divided among parallel cloud agents. For local work, Devin CLI runs in the terminal on macOS, Linux and Windows, while Devin Desktop provides an IDE with syntax highlighting, autocomplete, debugging tools, agent fleet management and shared context. Listed capabilities also include code completion, chat assistance, codebase indexing and terminal access. Integrations and workflows involve tools including GitHub, Linear, Slack, Teams, Datadog, Sentry, Jira, Confluence, AWS, Google Drive and PostgreSQL. The free plan has limited usage; Pro costs $20 a month and Max costs $200 a month. Paid-plan allowances refresh daily and weekly, with extra usage available at API pricing.
