Devin
Autonomous AIFully autonomous AI software engineer. Plans, codes, debugs, and deploys entire projects end-to-end.
About Devin
Devin is an autonomous AI software engineer developed by Cognition that can independently handle entire software development tasks. It has its own shell, code editor, and browser.
Unlike AI coding assistants that suggest code, Devin autonomously plans projects, writes code, fixes bugs, and deploys applications. It can handle multi-step tasks from start to finish.
Devin represents a new category of AI tool: the autonomous software engineer. While still early, it demonstrates the potential for AI to handle complex development tasks independently.
Key Features
- ✓Full Autonomy: Completes entire tasks from planning to deployment without human intervention.
- ✓Complex Planning: Breaks down complex tasks into manageable steps and executes them systematically.
- ✓Self-Correction: Debugs its own code and learns from mistakes to improve future performance.

Frequently Asked Questions
What makes Devin different from other AI coding tools?
Devin is fully autonomous, meaning it can complete entire tasks from start to finish without human intervention. Other AI tools are assistants that suggest code or answer questions, but Devin plans, codes, debugs, and deploys entire projects on its own.
How much does Devin cost?
Devin offers a Free plan for getting started. Paid self-serve plans start at $20/mo (Pro), $200/mo (Max), and $80/mo minimum for Teams. Enterprise pricing is custom. See devin.ai/pricing for current details.
Can Devin debug its own code?
Yes, one of Devin's key capabilities is self-correction. When it encounters errors or bugs, it can analyze the issue, identify the root cause, and fix the problem — then test to verify the fix works.
What kind of tasks can Devin handle?
Devin can handle complex multi-step software development tasks: building web applications, creating APIs, data processing pipelines, automation scripts, and more. Essentially, if you can describe it, Devin can potentially build it.
Is there a free version of Devin?
Yes, Devin offers a Free plan with limited usage, including access to Devin Review and DeepWiki. You can upgrade to Pro, Max, or Teams from app.devin.ai when you need more capacity.
