AutoGPT — Agent Frameworks Platform

AutoGPT is the pioneering autonomous AI agent platform — the project that introduced the world to recursive AI agents in early 2023 and was, for a time, the fastest-growing open-source project in GitHub's history. As of April 2026 it sits at 183,000+ stars, making it one of the four most-starred AI agent frameworks on GitHub.

Following a major 2024 rewrite, AutoGPT has shifted from the original recursive autonomous agent model to a visual workflow builder with composable 'blocks' — agents are built as inputs, outputs, and transformation functions stitched together visually. The 2026 platform offers continuous AI agents that can be triggered by external events, an agent marketplace with templates, and enterprise deployment features.

AutoGPT is open-source under MIT/Polyform Shield and free to self-host. The team raised $12M in October 2023 from GitHub Ventures and Redpoint. Despite the historical importance, multiple 2026 framework comparisons note that newer competitors like AutoGen, CrewAI, and LangGraph have largely eclipsed AutoGPT for production use cases — though the brand recognition and 183K stars keep it firmly in any AI agent conversation.
