Questions
Is EXTREMELY a free Manus 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 Manus and EXTREMELY? Manus works on the tasks you prompt or schedule. EXTREMELY runs a fleet of agents that each have a job and a schedule, pick their own steps, and build the tools they're missing.
Does EXTREMELY need credits? No. Agents run on the AI you bring: a Claude, ChatGPT or Copilot plan, API keys, or a local model via Ollama. No extra cost for the AI you already pay for.
