Hi HN, we were in the YC W26 batch and made Approxima, a web agent that could follow user journeys and verify them. Today, we made it open source (MIT) and its fully self-hostable.Here are some of the cool features of our platform:Explore Mode: instead of specifying the steps of a user journey yourself just give an agent a sentence or two describing what it looks like and the agent figures out the steps itself so it can follow them in the future.A/B Testing: You can tweak system prompts for the web agent and A/B test it within the platform itself.Self-healing: the steps for a journey update over time to align with your product s evolution. So ideally over time the amount of time and the number of tokens the agent takes trend down as it needs to make fewer decisions and think less.
