Hey HN, we’re Wei-Wei and Jeff. We’re building Momentic, QA agents that autonomously plan, explore, and bug-bash controls and user flows in your web, iOS, Android, and (soon) desktop apps to catch bugs. Here’s a demo: https://youtu.be/BFsM-Se1Fh8 We’re both software engineers that spent our careers on dev tooling and infra across companies like Robinhood, Retool, WeWork, and Qualtrics. Testing was always a pain in the ass (esp Playwright and Selenium), so we built agents to do it for us.…

From the discussion
A few top-level comments from Hacker News, shortened. Read the full thread on Hacker News.
Why is this better than running Opus 5.5 directly against my app with a custom Playwright-based harness for in my own subscription?
Questions: - I would always pick an open source tool I can strap to my custom harness over using a service like this. Do you somehow expect that no such competitor will arrive that performs as well? - If you are YC 2024 what have you been doing for 2 years? - The real edge here would be supporting mobile development…
I used this service very briefly, but it's too slow as it relies on the cloud and it's way too expensive since most developers use a subscription service. Even just Claude with basic prompts is better, but even better with skills.. and then even better with maestro scripts.
