OpenAI Codex — #3 in Coding

## Alternatives in Coding

- #1 **Claude Code** — Anthropic · No free plan
   Why it ranks here: The benchmark for long, autonomous tasks in large codebases; the agent that most popularized the terminal-first, delegate-the-work workflow.
   Official site: https://claude.com/product/claude-code

- #2 **Cursor** — Anysphere · Has a free plan
   Why it ranks here: The best AI-native IDE experience, with fast autocomplete and a choice of models; great if you prefer to review every change.
   Official site: https://cursor.com

- #4 **GitHub Copilot** — GitHub / Microsoft · Has a free plan
   Why it ranks here: The most GitHub-integrated option, with a free plan and Pro at US$10/month; less autonomous than the top three.
   Official site: https://github.com/features/copilot

- #5 **Devin Desktop** — Cognition · Has a free plan
   Why it ranks here: Solid Cursor alternative, now folded into Cognition's Devin family (Windsurf became Devin Desktop in Jun/2026); smaller community and ecosystem.
   Official site: https://devin.ai

- #6 **Aider** — Aider · Has a free plan
   Why it ranks here: Free, open source and good at mapping large codebases, but it's command-line only and requires paying separately for the chosen model's API.
   Official site: https://aider.chat

- #7 **Cline** — Cline Bot · Has a free plan
   Why it ranks here: Free and flexible (many models, MCP), but you pay for inference usage separately and it depends on VS Code.
   Official site: https://cline.bot

- #8 **Zed** — Zed Industries · Has a free plan
   Why it ranks here: Free, fast editor with optional AI; hosted-AI features cost US$10/month and it still has less agent autonomy than Claude Code or Cursor.
   Official site: https://zed.dev
