Devin

Devin is the autonomous AI software engineer built by Cognition. Where tools like Cursor and GitHub Copilot augment a developer in real time, Devin takes a task and works on it independently. Assign it a task from Slack, Microsoft Teams, a GitHub issue or the Devin web interface and it plans, codes, tests, debugs and submits a pull request. Devin runs in a persistent sandboxed cloud environment with its own terminal, editor and browser, and can spin up Windows, Mac and Linux virtual machines to build and test what it writes. It reads documentation, installs dependencies, runs tests, interprets error logs and iterates. A knowledge base learns codebase conventions and architectural patterns, improving output on repeat tasks. Cognition acquired Windsurf in 2025 and relaunched it as Devin Desktop in June 2026. All paid Devin plans include Devin Desktop IDE usage alongside cloud agent sessions, so the two products share one subscription and one pricing page. Other surfaces include the Devin CLI, Devin Review for automated pull request analysis, Automations for scheduled and event-triggered work, and DeepWiki for codebase documentation. Ask Devin and Devin Review moved from free to paid usage in April 2026. Cognition's own SWE-2 model, released in September 2026, runs in a slower mode on the free plan and is free to use on paid plans during its launch period. Integration depth covers the core developer workflow. Slack and Microsoft Teams handle task assignment and status, Linear and Jira trigger issue-based work, and GitHub, GitLab and Bitbucket handle pull requests and review, with Azure DevOps documented for Enterprise. On MCP Devin works both ways. It publishes an MCP server at mcp.devin.ai that external agents and IDEs connect into to manage sessions, playbooks, knowledge and schedules, and it acts as a client through its MCP marketplace. Enterprise adds SAML and OIDC single sign-on, SCIM, custom roles and a dedicated deployment option. Cognition names Citi, Mercedes-Benz, Goldman Sachs, Elevance, Dell, Santander, the U.S. Army and the U.S. Navy among its customers, alongside systems integrators Infosys and Cognizant and startups including Exa, Modal, Eight Sleep and OpenRouter. Its customers page adds GE Aerospace, RV Tech, AngelList, Itau, Nubank, Ripple Treasury, EBANX, Hippo, AHEAD, FE fundinfo, Litera, Bilt, Gumroad, Crossmint and Ramp. Cognition reports that Mercedes-Benz cut an eight-month legacy modernization project to eight days, and that Itau, described as Latin America's largest bank, fixes 70% of security vulnerabilities automatically. Nubank used Devin to refactor millions of lines of code. Pricing is public across all self-serve tiers, in USD. Free at $0 includes a light agent quota, limited model availability and unlimited inline edits and tab completions. The pricing page marks Devin Cloud, DeepWiki, Ask Devin and the Devin API as paid features. Pro at $20 per month adds increased quotas, frontier models from OpenAI, Anthropic, Google and SpaceXAI plus open-source models, Devin Cloud access and extra usage at API pricing past the included quota. Max at $200 per month raises quotas substantially. Teams carries an $80 monthly minimum, with full developer seats at $40 per month each, free flex seats that draw on shared credits, up to 200 members, centralized billing and an admin dashboard. Enterprise is quote-only with Agent Compute Unit billing and custom terms. No annual rate is published on any surface and the pricing page carries no billing toggle. What the entry price does not buy is worth stating. Usage past the included quota bills at API rates, so monthly spend is hard to predict for teams running concurrent sessions. Cognition's platform terms allow customer data to be used for model training by default, and the contractual opt-out is available only on paid tiers, so free users cannot exercise it. On the Teams tier only an administrator can. Cognition publishes a Trust Center whose compliance strip shows CCPA, SOC 2 Type 2 and ISO/IEC 27001:2022, each marked compliant, though the underlying reports sit behind an access request and an NDA. FedRAMP High covers Devin Desktop only. Cognition states that the cloud platform is FedRAMP High In-Process, with authorization slated for the second half of 2026. Devin Cloud sessions run asynchronously, with tasks taking minutes to hours, so interactive work happens in Devin Desktop or the Devin CLI instead. Developers who want an editor-first tool can also compare Cursor at $16/mo billed annually, and terminal-first developers Claude Code at $17/mo billed annually. Cloud sessions perform best on bounded, testable work with clear success criteria such as bug fixes with reproduction steps, test coverage, library migrations and documentation. Current state Q4 2026: Cognition raised over $2 billion at a $48 billion valuation in its Series E on 8 September 2026, led by Andreessen Horowitz and Accel, after raising over $1 billion at a $26 billion valuation in May. It reported run-rate revenue of almost $900 million at the Series E and said on 25 September that it had crossed $1 billion. September releases added the SWE-2 model, Microsoft Teams and Microsoft 365 support, sign-in with a ChatGPT plan and a MongoDB modernization partnership. Cognition also states that 89% of code committed by its own engineers is committed by Devin.
