Devin AI

Devin is an autonomous AI software engineering platform from Cognition designed for developers, engineering teams, and organizations that want to delegate software development tasks to an AI agent. It can work across repositories, understand existing codebases, write and modify code, execute commands, browse the web, run tests, debug problems, and create pull requests. Devin provides an embedded IDE, terminal, and interactive browser so developers can monitor its work and take control when needed.

The platform includes Ask Devin, which lets users explore a repository, ask questions about architecture and dependencies, and plan implementation before making code changes. Once a task is scoped, users can hand it to Agent mode for autonomous execution. Devin can work on bug fixes, feature development, refactoring, migrations, test creation, CI issues, dependency updates, and other engineering tasks.

Devin automatically indexes connected repositories and generates DeepWiki documentation containing architecture diagrams, summaries, and links to source material. It also supports integrations with tools such as GitHub, Slack, Jira, Linear, and MCP-compatible systems. The Devin MCP server enables external AI applications and IDEs to interact programmatically with Devin sessions, knowledge, playbooks, and scheduling.

For larger projects, teams can run multiple Devins in parallel, while the Devin API enables programmatic session creation and workflow automation. Devin supports hundreds of integrations and can work with tools including GitHub, Slack, Asana, AWS, Datadog, Linear, PostgreSQL, Snowflake, and others.

A Free plan is available for individuals with limited usage. Pro costs $20/month, Max costs $200/month, and Teams starts at $80/month with unlimited members. Paid plans combine included usage quotas with prepaid on-demand credits. Enterprise customers use Agent Compute Units (ACUs) under custom pricing.
