AutoGPT began as an open-source experiment in autonomous AI agents and its "Classic" version remains MIT-licensed, but the actively developed product today is a hosted platform (agpt.co) with a visual agent builder, credit-based execution billing, and a commercial marketplace — the parts most people now interact with sit behind that paid hosted layer.

Multica is the closer match if you want a broad, open-source agent framework with wide service integrations. Letta is the better pick if persistent memory and stateful agents that improve over time matter more to you than task automation breadth, and Suna is worth a look if you want an agent focused on handling real-world tasks autonomously out of the box.
