πŸ€– AI Coding Agents

172 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.
