Devin

Devin is the fully autonomous AI software engineer built by Cognition. Where tools like Cursor and GitHub Copilot augment a developer in real time, Devin operates independently. Assign it a task from Slack, 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. 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 rebranded it as Devin Desktop. All paid Devin plans now include Devin Desktop IDE usage alongside cloud agent sessions, so the two products share one subscription and one pricing page. Other surfaces include Devin CLI, Devin Review for automated pull request analysis, Devin Windows VM and DeepWiki for codebase documentation. Ask Devin and Devin Review moved from free to paid tiers in April 2026. SWE 1.7 is available across all tiers. Integration depth covers the core developer workflow. Slack handles task assignment and status, Linear and Jira trigger issue-based work, and GitHub, GitLab and Bitbucket handle pull requests and review. Microsoft Teams is supported alongside Slack. 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 with centralized admin controls. 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 Vimeo, Hippo, AHEAD, AngelList, Evinova, RV Tech, FE fundinfo, Litera, Bilt, Gumroad, Crossmint, Ramp and Nubank. 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 migrate a multi-million line ETL monolith. Verified 2026-08-07. 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. Devin Review and DeepWiki are not on the free plan. Pro at $20 per month adds increased quotas, access to OpenAI, Anthropic and Google frontier models, free use of SWE 1.7, Devin Cloud access and pay-as-you-go billing past the included quota. Max at $200 per month raises quotas substantially. Teams is $80 per month plus $40 per month per full developer seat, adding unlimited members, shared collaboration, 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. Devin is not the right fit for developers who want real-time collaborative coding in the editor. Cursor at $16/mo billed annually and Claude Code at $17/mo billed annually give immediate interactive responses. Devin runs asynchronously, with tasks taking minutes to hours, which rules it out for tight iteration loops and pair programming. It performs best on bounded, testable work with clear success criteria such as bug fixes with reproduction steps, test coverage, library migrations and documentation. Current state Q3 2026: Cognition raised over $1 billion at a $26 billion valuation on 27 May 2026, led by Lux Capital, General Catalyst and 8VC, with Founders Fund and Elad Gil among existing investors. It reported run-rate revenue of $492 million and enterprise usage up more than tenfold since the start of the year. Cognition also states that 89% of code committed by its own engineers is committed by Devin. Windsurf has been fully rebranded as Devin Desktop.
