Devin

Devin is an autonomous AI coding agent built by Cognition, designed to plan, write, test, and ship code with significantly less hand-holding than traditional AI coding assistants. Rather than operating purely as an in-editor autocomplete tool, Devin runs in a sandboxed environment with its own shell, code editor, and web browser, letting it investigate a codebase, execute multi-step engineering workflows, run tests, recover from errors, and open pull requests largely on its own while a human reviews and approves the results.

Cognition introduced Devin in March 2024, branding it as one of the first AI software engineers, which generated enormous attention alongside notable scrutiny of its early benchmark claims and demo methodology. Since then, the product has gone through several major revisions, including Devin 2.0, and matured into a more scoped, supervised coding agent used for tasks like large-scale code migrations, PR review and visual QA, documentation generation via DeepWiki, issue triage, and scheduled maintenance chores. Devin integrates with GitHub, GitLab, Bitbucket, Linear, Jira, Slack, and Microsoft Teams, and supports fine-tuning on a team's own past migrations to speed up repetitive, high-volume engineering work.

Devin is used by engineering teams at companies including Nubank, Ramp, Goldman Sachs, and Microsoft, with Nubank reporting 8-12x efficiency gains and over 20x cost savings on a multi-year ETL migration project delegated to fleets of parallel Devin agents. Cognition also owns Windsurf, an AI-native code editor now marketed as Devin Desktop, extending Devin's agent capabilities into a full IDE experience. Plans range from a free tier through Pro, Max, Teams, and Enterprise, with VPC deployment and SSO available for organizations with strict security requirements.

Devin's Free plan costs $0/month with a light quota to code with agents, limited model availability, and unlimited inline edits and Tab completions. Pro costs $20/month and adds increased quotas, access to OpenAI, Claude, and Gemini frontier models, free use of SWE 1.7 and leading open-source models, Devin Cloud access, and the ability to purchase extra usage at API pricing. Max costs $200/month with everything in Pro plus significantly higher usage quotas for power users. Teams costs $80/month as a base team fee plus $40/month per full developer seat, and includes unlimited team members via flex seats, sharing and collaboration, centralized billing, an admin dashboard with analytics, and priority support. Enterprise is custom-priced ("let's talk") and adds highest-priority support, dedicated account management, SAML/OIDC SSO, centralized enterprise admin controls, and dedicated VPC deployment options. Usage allowances refresh daily and weekly, and extra usage beyond included quotas is billed at API pricing.
