Questions
Is EXTREMELY a free Gumloop alternative? Yes. Open source (AGPL-3.0), runs on your own computer, on the AI you already have. Optional hosting is US$399 a year.
What's the difference between Gumloop and EXTREMELY? Both run AI agents. Gumloop runs them on its platform and bills credits plus an orchestration fee. EXTREMELY runs on your computer and your own AI, and its Agency Engineer builds the tools agents are missing.
Can I use the AI I already pay for? Yes. Bring a Claude, ChatGPT or Copilot plan, API keys (Anthropic, OpenAI, Google, OpenRouter...) or a local model through Ollama. No extra cost on top.
