This is a completely free open source project that does what ChatGPT Operator does. In other words, it browses the web autonomously based on a goal you set. It's in 0.2 version, but in case somebody is thinking of tinkering with it, go ahead. It's built on NextJS and Playwright, and you can connect to your own local LLM or use OpenAI. Ask it to do anything like book a flight, find the best deals, whatever.
