Devin

Devin by Cognition is the world's first fully autonomous AI software engineer. Unlike code assistants that help you write code, Devin independently plans, codes, debugs, and deploys software given a task description in natural language. It operates in its own sandboxed environment with a code editor, terminal, and web browser — essentially working like a remote junior developer.

• End-to-end task execution — takes a ticket or task description and works through it autonomously: planning the approach, writing code, running tests, debugging failures, and submitting a PR
• Environment management — sets up its own development environment, installs dependencies, and configures tooling as needed
• Web research — browses documentation, Stack Overflow, and API references to solve problems it encounters
• CI/CD integration — runs in the background and submits pull requests when work is complete
• Long-running tasks — handles tasks that take hours, reporting progress and asking clarifying questions when needed

Engineering teams use Devin to handle backlog items, write migrations, set up boilerplate, and tackle well-defined tasks that don't require deep product intuition. It frees up senior developers to focus on architecture and complex problem-solving while Devin handles implementation work.

Devin represents a new paradigm in AI coding — not a tool you use inside your editor, but an autonomous agent you assign work to and review results from, much like managing a remote contractor.

1. Visit cognition.ai and request access or sign up for the available plan.
2. Devin is accessed through a web-based interface — there is nothing to install locally. You interact with it by typing task descriptions in natural language.
3. Pricing:
   • Team ($500/mo): Includes a pool of Agent Compute Units (ACUs), integration with GitHub, Slack notifications
   • Additional ACUs available as needed for larger workloads
4. Assign a task by describing it clearly — e.g., “Set up a REST API endpoint for user registration with email verification using our existing Express + PostgreSQL stack.”
5. Devin works in the background. Monitor progress in real time through the session view, which shows its editor, terminal, and browser activity. Review and merge the PR it submits when complete.
