Devin

Devin is the fully autonomous AI software engineer built by Cognition, which has raised over $1 billion at a $26 billion valuation from investors including Lux Capital, General Catalyst, 8VC, Founders Fund, and Elad Gil. Where tools like Cursor and GitHub Copilot augment human developers in real time, Devin operates independently: assign it a task via Slack, a GitHub issue, or the Devin web interface, and it plans, codes, tests, debugs, and submits a pull request without supervision. Devin runs in a persistent sandboxed cloud environment with its own terminal, code editor, and browser. It reads documentation, searches for relevant information, installs dependencies, runs tests, interprets error logs, and iterates autonomously. The knowledge base feature learns codebase conventions and architectural patterns, improving output quality on repeat tasks. Cognition reports Devin successfully completes approximately 75% of assigned tasks, with the remaining 25% requiring human intervention. Cognition acquired Windsurf in 2025 and has since rebranded it as Devin Desktop, unifying both products under the Devin brand. All paid Devin plans now include Devin Desktop (formerly Windsurf) IDE usage alongside cloud-based autonomous engineering sessions. This bundling has no equivalent among competitors: Cursor, Claude Code, and GitHub Copilot are all single-surface tools with no autonomous background agent included. Additional product surfaces include Devin CLI for terminal-based agent access, Devin Review for automated pull request analysis, Devin Windows VM for Windows development environments, and DeepWiki for AI-powered codebase documentation. As of April 2026, Ask Devin and Devin Review are now paid features included with subscription plans, having previously been available for free. The latest model, SWE 1.6, is available across all tiers. Integration depth covers the core developer workflow: Slack for task assignment and status updates, Linear for issue-based task triggering, GitHub for PR creation and code review, VS Code via the Devin extension, Jira for project management, and MCP for connecting external tools and data sources. All integrations are included on the Pro plan. Enterprise adds SAML/OIDC SSO and centralized admin controls. Named customers include Goldman Sachs, Microsoft, Anduril, Ramp, MongoDB, Santander, Zillow, the U.S. Army, Intact Insurance, and Nubank. Nubank used Devin to migrate a multi-million line ETL monolith, achieving 8 to 12x engineering efficiency gains and over 20x cost savings versus manual migration. Missing from the current integration set: no native Confluence, Notion, or documentation platform connections beyond DeepWiki. Pricing is fully public across all tiers. Free at $0 includes limited Devin usage, Devin Review, DeepWiki, limited model availability, and unlimited inline edits and tab completions. Pro at $20/month adds increased quotas with access to OpenAI, Claude, and Gemini frontier models, full model availability, free use of SWE 1.6, access to Devin Cloud, and pay-as-you-go billing for usage past included quota. Max at $200/month provides significantly higher quotas for developers running heavy autonomous workflows. Teams at $80/month base plus $40/month per full developer seat adds unlimited team members, shared collaboration, centralized billing, and an admin dashboard with analytics. Enterprise pricing is custom with SAML/OIDC SSO, dedicated account management, Agent Compute Unit billing, and custom contract terms. Devin is not the right fit for developers who want real-time collaborative coding in their IDE. Cursor at $20/month and Claude Code at $20/month both provide immediate, interactive agentic responses within the editor. Devin operates asynchronously: tasks take minutes to hours, making it unsuitable for tight iteration loops or pair programming workflows. Developers should also be realistic about task scope: Devin performs best on well-bounded, testable tasks with clear success criteria such as bug fixes with reproduction steps, test coverage expansion, library migrations, and documentation updates. Open-ended feature development with ambiguous requirements produces significantly lower completion rates. Current state Q2 2026: Cognition raised over $1 billion at a $26 billion valuation in May 2026, led by Lux Capital, General Catalyst, and 8VC. Windsurf has been fully rebranded as Devin Desktop, integrating the IDE experience under the Devin product umbrella. SWE 1.6, Cognition's latest model, is now available across all tiers. The Max tier at $200/month is a new addition for high-volume autonomous workflows. Teams pricing has been restructured to $80/month base plus $40/month per full developer seat, a significant reduction from the prior $500/month Team plan. Ask Devin and Devin Review, previously free, are now paid features included with subscription plans as of April 2026. Devin CLI and Devin Windows VM have launched as additional product surfaces. Cognition holds SOC 2 Type II, ISO 27001, and CCPA certifications confirmed via the Cognition Trust Center.
