# Fair comparisons for choosing how you build with AI

> No invented benchmarks, no winners declared. These comparisons explain the trade-offs so you can decide — and show how to test options on your own repo.

- [ADE vs IDE: what changes when agents do the typing](https://runtallos.com/compare/ade-vs-ide.md): ADE vs IDE: an IDE is built for a person editing files; an ADE is built for AI agents running tasks in parallel. Differences, tradeoffs, when to use each.
- [Tallos vs AI code editors: built for multi-agent development, not added as an AI sidebar](https://runtallos.com/compare/tallos-vs-ai-code-editors.md): Tallos vs AI code editors: editors add AI to hands-on coding; Tallos runs many coding agents in parallel, each in its own workspace. What each does best.
- [Claude Code vs Codex: a neutral comparison, and why you can run both](https://runtallos.com/compare/claude-code-vs-codex.md): Claude Code vs Codex: both are AI coding agents that run as CLIs in your terminal. See how they compare, and how to test both on your own repo in parallel.
- [One AI agent vs many: when parallel agents are worth it](https://runtallos.com/compare/one-agent-vs-many.md): One AI coding agent or many? Compare sequential and parallel agent work, the real cost of coordination, and four patterns that make many agents pay off.
- [Claude Code vs Codex vs Gemini CLI: three agent CLIs, compared fairly](https://runtallos.com/compare/claude-code-vs-codex-vs-gemini-cli.md): Claude Code vs Codex vs Gemini CLI: three AI coding agents that run in your terminal. Vendors, install, sign-in, and how to test all three on your repo.
