Best AI coding agents
These are the coding tools listed on AgentAtlas. Most of them edit a repository you already have. A smaller group starts a new web app from a prompt. CodeRabbit is separate: it reviews a pull request and does not write the feature.
Names are alphabetical inside each group. This is not a scored ranking. A paid placement is labeled Sponsored on that tool's page, and none of these listings are sponsored.
How to choose
Pick from where the code lives. Cursor and GitHub Copilot sit in the editor. Claude Code, Codex, Aider, Cline, and OpenCode can work from a terminal or an IDE, and the open source ones expect a model you connect. Continue was acquired by Cursor; its open-source code remains available. Jules, Codex, and Devin can also keep working in the cloud and return a pull request. Bolt, v0, Lovable, and Replit are the wrong list when you already have a large repository to change.
Agents and editors for a repository
These read a project and change it. Aider, Cline, OpenCode, and OpenHands are open source. Continue was acquired by Cursor, and its open-source code remains available. The others are hosted products.
