Devin is Cognition's autonomous AI software engineer, a cloud-based coding agent that plans, writes, tests, and ships code end to end rather than just autocompleting it inside an editor. Cognition (formerly Cognition Labs), a San Francisco-based AI company, builds and operates Devin as its flagship agentic product, alongside the related Devin Desktop IDE and the Devin Review code-review tool.
Who builds it
- Built and operated by Cognition, an AI research and product company.
- Devin is marketed as "the AI software engineer" rather than a copilot: it is designed to take a task end to end, from planning through pull request, with a human reviewing the result rather than co-piloting line by line.
Core features
- Autonomous task execution — code migrations, large refactors, bug fixes, CI-failure resolution, and documentation of legacy systems — run largely unattended inside "Devin Cloud" sandboxes.
- Learns a team's codebase and conventions over repeated tasks, and can be assigned work directly from Slack, Linear, Jira, GitHub, and other connected tools.
- Devin Review: AI-assisted pull-request review that groups related diff hunks, explains changes, flags bugs by severity, and scans for security issues (CWE-classified) on GitHub and GitLab.
- Access to frontier models from OpenAI, Anthropic, and Google, plus Cognition's own SWE-1.6 model, included at no extra cost on paid plans.
- Desktop and CLI clients (Devin Desktop, Devin CLI) for steering and monitoring agents locally alongside the cloud agent.
Pricing
Devin combines flat subscription fees with usage-based "ACUs" (Agent Compute Units, each roughly 15 minutes of active agent work):
- Free — $0/month: limited quota, restricted model selection, unlimited inline edits and Tab completions.
- Pro — $20/month: larger quotas, full access to OpenAI/Claude/Gemini models plus free SWE-1.6 and open-source models, Devin Cloud access, pay-as-you-go extra usage.
- Max — $200/month: everything in Pro with significantly higher quotas.
- Teams — $80/month base plus $40/month per full developer seat: unlimited members, shared billing, an admin dashboard, and priority support.
- Enterprise — custom pricing: dedicated account management, SAML/OIDC SSO, centralized admin controls, and an optional dedicated VPC deployment.
Devin is not open source. Cognition instead runs a "Devin Open Source Initiative" that gives selected open-source maintainers free Teams-plan usage to work down their project backlogs, while Devin's own code and models stay proprietary.
Who it's for
Devin targets engineering teams that want to delegate well-scoped, end-to-end tasks — migrations, bug triage, PR review, legacy documentation — to an agent rather than pairing with a copilot line by line. Cognition cites Nubank's use of Devin for ETL migration work, reporting an 8-12x efficiency gain, as an example of the enterprise use case. Enterprise buyers needing SSO, VPC isolation, or centralized admin controls are pointed to the custom Enterprise tier, while smaller teams and individuals can start on the Free or Pro plans.
