Best AI coding agents for developers who want an agent to write and ship code

Agents that plan, edit, run and ship code across many steps, from a terminal or a cloud sandbox.

Tier S

  1. Claude Code

    Strongest option for deep, multi-file work on a real repo. Supports MCP, hooks and subagents.

  2. OpenAI Codex

    On par with Claude Code at the top. The best pick if you already pay for ChatGPT.

Tier A

  1. Devin

    Good for assign-and-forget tickets. Less hands-on control than terminal agents.

  2. Kiro

    Turning specs into tasks keeps bigger vibe-coded projects on the rails.

  3. OpenCode

    The best open-source pick if you want to choose your own model.

Tier B

  1. Aider

    Mature and transparent, with clean commits. Less autonomous than newer agents.

  2. Google Jules

    Handy free async agent for small tasks. Not a daily driver for most builders.
