Questions
Is EXTREMELY a free Lindy 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 Lindy and EXTREMELY? Lindy is an AI assistant you ask in Slack, email or meetings, paid in credits. EXTREMELY runs a fleet of agents with jobs and schedules that build the tools they're missing, on your own AI.
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.
