About Devin

Devin by Cognition is the first fully autonomous AI software engineer. It can plan, write code, debug, deploy, and handle entire development tasks from start to finish using its own code editor, terminal, and browser. Devin works alongside human engineers on real-world codebases, handling tasks like bug fixes, feature implementations, and codebase migrations with minimal human intervention.

About OpenAI Codex

OpenAI Codex is a cloud-based autonomous coding agent that runs in a sandboxed environment. It can read codebases, write and edit code across multiple files, run tests, and submit pull requests—all from a natural language task description. Codex operates asynchronously, handling tasks in parallel while developers focus on other work. Built on OpenAI's reasoning models, it excels at feature implementation, bug fixes, and refactoring on real-world repositories.

Frequently Asked Questions

What is a coding agent?

A coding agent is an AI tool that helps write, debug, review, and refactor code. They range from autocomplete tools to fully autonomous agents that can implement entire features, run tests, and submit pull requests.

Will coding agents replace developers?

No, but they significantly increase developer productivity. Coding agents handle routine implementation and debugging, freeing developers to focus on architecture, design decisions, and complex problem-solving.

How do I choose between GitHub Copilot, Cursor, and Claude Code?

GitHub Copilot is best for inline autocomplete and broad IDE support. Cursor provides the deepest codebase-aware chat experience. Claude Code excels at autonomous multi-file tasks from the terminal. Many developers use multiple tools.
