AutoGPT

Useful work is rarely one prompt; it is a chain of steps, and AutoGPT is an open-source platform for handing that whole chain to an agent. Describe the outcome in plain English through AutoPilot and the conversation turns into a working agent, or open the Build canvas and wire the blocks yourself when a step needs exact control. Finished agents run on demand, on a schedule or from a trigger, and an Agents dashboard collects every run, its cost, and whatever is waiting on a human. A Marketplace carries ready-made community agents you can pull into your own library and adapt.

Running it splits two ways. The paid hosted platform manages infrastructure, model access and credentials, bills by agent run, and per the project offers hundreds of models plus 45+ connected apps such as Gmail, Slack, Notion, GitHub and Linear. Self-hosting charges no license fee but leaves Docker and your own model API keys to you. The platform code sits under Polyform Shield while the classic standalone agent and the rest stay MIT.
