Devin

Devin, developed by Cognition (cognition.ai), is the world's first autonomous AI software engineer. Unlike traditional AI coding assistants that require constant human guidance, Devin operates independently to plan, write, test, and ship production-quality code. It works directly inside your codebase, integrates with the tools your engineering team already uses, and learns from past sessions to improve over time. Deployed at some of the largest and most complex institutions globally, Devin represents a paradigm shift in how software is built.

Core Capabilities

Devin handles the full software development lifecycle autonomously. It can plan and execute complex engineering tasks such as code migrations, legacy system modernizations, and large-scale refactors. For pull request workflows, Devin Review automatically identifies and resolves bugs, performs visual QA using full browser and desktop access, and intelligently organizes code diffs for human review. Devin also auto-generates documentation and system diagrams for legacy codebases via DeepWiki, providing comprehensive visibility into unfamiliar systems.

Key use cases include code migration and refactoring (assigning a fleet of agents to migrate all repos in parallel), issue triage and bug fixing (investigating Datadog incidents, routing Slack bug reports, fixing CI failures), scheduled chores (daily QA, release notes, maintaining documentation), automated ticket resolution, unit and E2E testing, performance optimization, web research and scraping, and repetitive browser task automation.

Product Suite

Devin offers multiple form factors to suit different workflows. Devin Cloud provides cloud-hosted autonomous agents accessible via a web interface. Devin Desktop (formerly Windsurf) is a full-featured IDE with built-in AI agent capabilities, unlimited inline edits, and Tab completions. Devin CLI brings Devin's power directly to the terminal. Devin Windows VM extends support to Windows-based development environments. All products leverage Cognition's latest SWE 1.6 model, which delivers improved task completion and speed over previous versions.

Enterprise-Grade Integration

Devin integrates with hundreds of tools in the modern engineering stack: GitHub, GitLab, Bitbucket for version control; Linear and Jira for issue tracking; Slack and Microsoft Teams for communication; Datadog and Sentry for observability; and Confluence, Notion, and Google Drive for knowledge management. It ships PRs the way your team does, picking up review feedback and CI results to get each PR approved and merged. Devin can be assigned tickets directly in Linear, tagged in Slack conversations to surface context or turn discussions into PRs, and automated entirely via the Devin API and Devin Automations.

Proven Results at Scale

In production at major enterprises, Devin has demonstrated transformative results. A prominent case study involves Nubank, the Brazilian fintech giant: Devin handled a core ETL migration of over 6 million lines of code and approximately 100,000 data class implementations. The result was an 8–12x efficiency gain in engineering hours and over 20x cost savings compared to manual execution by a team of over 1,000 engineers. Devin completed in weeks what was projected to take 18 months. Other customers include Goldman Sachs, Mercedes-Benz, Ramp, Anduril, Infosys, Cognizant, Itaú, and RV Tech.

Pricing and Plans

Devin offers a tiered pricing model to accommodate individuals and teams of all sizes. A Free plan provides a light quota including unlimited inline edits and Tab completions. The Pro plan at $20/month adds increased quotas, access to frontier models (OpenAI, Claude, Gemini), SWE 1.6 access, and Devin Cloud agents. The Max plan at $200/month offers significantly higher quotas for power users. Teams start at $80/month for the base plan plus $40/month per full developer seat, adding unlimited team members, sharing and collaboration, centralized billing, and admin analytics. Enterprise plans include custom pricing with SAML/OIDC SSO, dedicated deployment, SLAs, and dedicated account management. All paid plans come with a free trial to evaluate the platform.
