π€ AI Coding Agents
181 articles. Compare AI coding agents. Reviews, setup guides, one-week reviews, and honest comparisons.
AI coding agents changed how a lot of us write software day to day, and this is where we track the ones worth using: Claude Code, Cursor, Aider, Codex CLI, Gemini CLI, OpenCode, and newer entrants worth watching. If you're deciding which agent fits your workflow β terminal-first, IDE-integrated, or more autonomous β the comparisons below draw on hands-on use where we've run a tool ourselves, alongside official documentation and published benchmarks. Coverage includes setup guides for pairing a specific agent with a specific model, one-week reviews after real daily use, and direct comparisons when two tools compete for the same job.
Quick guide to picking an agent
- Want autonomous, long-running workflows β look at Claude Code or the multi-agent tools in Other Agents.
- Prefer a full IDE experience β Cursor is built around that; Aider and the terminal agents are not.
- Terminal-first, model-agnostic β Aider, Codex CLI, and OpenCode all let you swap the underlying model freely.
- Want an open-source alternative you can inspect or self-host β OpenCode and Aider are both open source.
