What is Devin?
Devin is an AI software engineering agent made by Cognition. It can take on development tasks such as planning features, fixing bugs, upgrading dependencies, investigating incidents, reviewing code, and preparing pull requests. Devin can operate through cloud agents or on a developer's machine, and larger assignments can be divided among multiple agents running in parallel.
The agent explores repositories to understand their architecture, writes and changes code, and tests its work using its own computing environment. It can use Windows, macOS, and Linux virtual machines, open a browser for end-to-end testing, and record test sessions for review. Teams can also invoke Devin from development workflows and collaboration tools.
Key Features
- Autonomous coding sessions: Devin can plan an assigned task, inspect relevant repositories, implement changes, run checks, and produce a pull request for human review.
- Cloud and local operation: Teams can delegate work to persistent cloud agents or use Devin through its desktop and command-line experiences.
- Independent testing environments: The agent can create Windows, macOS, or Linux virtual machines, test applications in a browser, and record its interactions.
- Parallel task execution: Large engineering assignments can be split across multiple cloud agents, with Devin coordinating the work and reporting progress.
- Code review and security checks: Devin Review is designed to identify bugs and vulnerabilities before production and can assign discovered issues back to Devin for fixes.
- Workflow integrations and automations: Devin can respond when tagged in Slack or Teams and can handle incoming bugs, failed CI runs, and alerts through configured automations.
Use Cases
- Implement product features and verify user flows with end-to-end browser tests.
- Diagnose bugs, failed builds, API errors, and production incidents, then prepare fixes.
- Perform dependency upgrades, architecture changes, and other extended engineering tasks.
- Review pull requests for defects or security vulnerabilities and propose corrections.
- Build and maintain codebase documentation, diagrams, and architecture maps.
Pricing
Devin uses a freemium model. The Free plan costs $0 and includes a light agent quota, limited model access, inline edits, and Tab completions. Pro costs $20 per month, while Max costs $200 per month and provides higher quotas. The Teams plan costs $80 per month plus $40 per month for each full developer seat. Enterprise pricing is customized through the sales team. Paid usage allowances refresh daily and weekly, with additional usage available at API pricing.
Who Is It For?
Devin is intended for individual developers, engineering teams, and enterprises that want an AI agent to complete defined software tasks. It is particularly relevant to teams managing multiple repositories, recurring maintenance, code review, CI failures, security work, and production alerts.
