Six agents, side by side
Every tool here reads your code, runs commands and edits files from a terminal. The differences are in the bill, the models and the licence.
| tool | licence | what you pay / need | models | where it runs |
|---|---|---|---|---|
| PoopRusteek | MIT | Nothing: a free chat.deepseek.com session, no API key | DeepSeek web; plus OpenAI-compatible, Anthropic and Gemini endpoints | Terminal — Windows, macOS (Apple Silicon), Linux |
| Claude Code | Proprietary | Claude Pro ($20/mo), Max (from $100/mo), Team, Enterprise, or Anthropic API usage. Not in the Free plan | Claude; third-party providers in the CLI and IDE plugins | Terminal, VS Code, JetBrains, desktop app, web |
| Codex CLI | Apache-2.0 | A ChatGPT plan (Free through Enterprise, within its usage limits) or OpenAI API billing | OpenAI | Terminal — macOS, Linux, Windows |
| Gemini CLI | Apache-2.0 | Free with a Google account: 60 requests/min, 1,000/day. Paid via Gemini API key or Vertex AI | Gemini, 1M-token context | Terminal (Node.js) |
| aider | Apache-2.0 | The tool is free; you pay whichever model provider you connect, or run local models | Almost any LLM, including local ones | Terminal (Python) |
| OpenCode | MIT | The tool is free; bring your own provider and API key, or local models | Many providers, including local ones | Terminal TUI |
── where it fits
Choose PoopRusteek if…
No tool wins every column. This is the honest version.
it’s a good fit when
- ✓you want an agentic workflow without a subscription or an API bill
- ✓you want to try working with an agent before paying for one
- ✓you want parallel chats, sub-agents and a GOAL loop that iterates until an evaluator agrees
- ✓you want one interface over several providers, or a free OpenAI-compatible endpoint on localhost
- ✓your project already has CLAUDE.md, AGENTS.md or GEMINI.md and you want it to keep working
look elsewhere when
- ✗you need the strongest frontier model on large, hard codebases — that’s what a Claude or ChatGPT plan buys
- ✗your team needs vendor support, admin controls or compliance guarantees
- ✗your policy rules out unofficial APIs — PoopRusteek’s default DeepSeek backend is one
- ✗you’re on an Intel Mac, which has no build
