AgentGPT
Free browser-based autonomous agent demo — archived in 2026 and no longer maintained
What AgentGPT is
AgentGPT is a browser-based tool from Reworkd where you name a goal and an autonomous AI agent plans and executes tasks toward it. The open-source repo was archived in January 2026 with its last release in November 2023, and Reworkd has pivoted to web-scraping AI agents, so the hosted site still loads but receives no updates, fixes, or new model support. Useful as a free sandbox to understand autonomous-agent behavior — not something to build a client service on.
Key features
- Goal-driven autonomous agents: enter a name and objective, the agent decomposes and executes tasks
- Runs entirely in the browser with no setup
- Prebuilt example agents and templates (research, planning, study guides)
- Open-source codebase (archived) you can still self-host from GitHub
- Free to try with limited runs on the hosted version
💰 Sell it as a service
The offer
Not a sellable platform — use it as a free demo prop in sales conversations to show prospects what autonomous agents do, then close the actual build on a maintained platform like Lindy or Relevance AI.
What to charge
Charge $0 against this tool directly. Fold it into a paid AI-opportunity audit ($500-$1,500) where you demo agent concepts, then quote the real implementation at $2,000-$5,000 on maintained tooling.
How it gets delivered
Run a live AgentGPT session in the discovery call to make 'AI agent' concrete for the client, then map their use case onto a supported platform. Do not deploy client work on an archived, unpatched codebase.
This is one offer. AI Operator Academy is where operators build the full stack — packaging, pricing, fulfillment, and a peer group selling the same services. $999/yr.
