Good work. But what makes this different than just another feature in Gemini Code assist or Github copilot?

Thanks! To execute these tests reliably you would need custom browser fleets, ephemeral environments, data seeding and device farms

what kinds of tests does it generate and how's this different from the tens of code review startups out there?

The system focuses on going beyond the happy path and generating edge case tests that try to break the application. For example, a Grafana PR added visual drag feedback to query cards. The system came up with an edge case like - does drag feedback still work when there's only one card in the list, with nothing to reorder against?

The market timing on this is perfect - it fills a major current gap I've seen emerging.

I've heard a few stories of QA departments being near-burnout due to the increased rate developers are shipping at these days. Even we're looking for any available QA resources we can pull in here.

No harm meant with the question - but what's the advantage over Claude Code + the GitHub integrations?

We evaluated test generation using Claude code and our purpose built harness and measured the quality of tests in catching the unknown unknowns. We noticed Claude Code misses the second order effects that actually break applications. You also need infrastructure to execute the tests - browser fleets, ephemeral environments, data seeding need to be handled

I really want automated QA to work better! It's a great thing to work on. Some feedback: - I definitely don't want three long new messages on every PR. Max 1, ideally none? Codex does a great job just using emoji. - The replay is cool. I don't make a website, so maybe I'm not the target market, but I'd like QA for our backend. - Honestly, I'd rather just run a massive QA run every day, and then have any failures bise…

Agree on your last point and it's going to be a very bitter lesson. In any case, you probably wanna shift alot of the code verification as left as possible so doing review at PR time isnt the right strat imo. And claude/codex are well positioned to do the local review.

The interesting question to me is not whether the system can generate a plausible PR-time test, but whether the useful ones survive after the PR is gone. If Canary catches a real regression, how often can that check be promoted into a stable long-lived regression test without turning into a flaky, environment-coupled browser script? That conversion rate feels closer to the real moat than the generation demo.

If that's what you guys are bringing, you should put that more up front; focus on making it clear you're providing ingredients that Claude et al will not be providing on their own without Real Actual Software to do it.

Isn’t the last point the case with every AI startup? Nobody has a moat and it’s tough to build one because the playing field is so level.
