PoopRusteek vs Claude Code
Claude Code is Anthropic’s agentic coding tool. PoopRusteek is a free, open-source terminal agent in Rust. Here’s what’s the same, what isn’t, and when each one is the right call.
- Claude Code needs a paid Claude plan (Pro from $20 a month) or Anthropic API credits. PoopRusteek runs on a free DeepSeek web session with no key.
- Claude Code runs Claude, from the company that trains it. PoopRusteek defaults to DeepSeek and can add OpenAI-compatible, Anthropic or Gemini endpoints.
- Your CLAUDE.md, .claude/skills and the MCP servers configured for Claude Desktop or Claude CLI are picked up by PoopRusteek as they are.

── what carries over
Your setup comes with you
- ⇄An agent loop that reads code, runs shell commands, edits files and asks before anything with side effects
- ⇄Slash commands, CLAUDE.md project instructions and markdown skills in .claude/skills
- ⇄MCP servers — PoopRusteek even discovers the ones you configured for Claude Desktop and Claude CLI
- ⇄Sub-agents that take a task away and bring back only the answer
── what’s different
Where they part ways
- The bill
- Claude Code is a paid product. PoopRusteek’s default backend costs nothing, because it drives the DeepSeek web chat that is free to use.
- The model
- Claude Code talks to Claude; PoopRusteek talks to DeepSeek unless you add another provider. On long, difficult tasks the model matters more than the harness — that is the real reason to pay for Claude.
- The surfaces
- Claude Code also lives in IDEs, a desktop app and the browser. PoopRusteek is a terminal program, plus a local OpenAI-compatible server and an ACP mode for editors.
- The extras
- PoopRusteek adds a GOAL loop with a separate evaluator agent, offline RAG over skills, MCP tools and chat history, and ten colour themes.
- The fine print
- DeepSeek’s web API is unofficial and can change without notice. Claude Code is a supported product with a vendor behind it.

── switching
Moving over in three steps
01
Install PoopRusteek: one file on Windows, one line on macOS and Linux.
02
Start it in your project. CLAUDE.md and .claude/skills load automatically; MCP servers from your Claude Desktop and Claude CLI configs are discovered.
03
Paste your DeepSeek session token when onboarding asks — or add an Anthropic endpoint with /providers and your API key to keep using Claude models.
