Been following this maker across two launches now (the original disposable-environments version and now this PR-testing follow-up). What I like about this second version is that it's actually solving the exact bottleneck the maker described in the first launch's comments - reviewing a PR still means clicking through the app yourself to see if it actually works. Getting a video walkthrough and verdict posted right on GitHub means you don't have to context-switch into a separate environment to check. It's still early beta (first 100 users, waitlist invite code), so I'm rating it for the idea and execution I've seen in the thread rather than months of daily use.
