Show HN: Open-Sourced Approxima, Our Agentic QA Tool to Catch Breakages Faster

https://github.com/Approxima-AI/Approxima-OSS
1•Intragalactic•1h ago
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.
