""Autonomously, an Antigravity Agent writes code for a new frontend feature, uses the terminal to launch localhost, and actuates the browser to test that the new feature works."

very interesting times; i'm glad to see browser automation becoming more mainstream as part of the ai-assisted dev loop for testing. (disclosure: started the selenium project, now working on something similar for a vibe coding context)

Most people are missing the point here. Testing the GUI/feature more reliable is something that Gemini 3 could unlock (looking at the ScreenSpot-Pro benchmark and its general improvement on visual understanding). At least for the (hobby-)projects I attempted this was really a bottleneck having to always test the GUI after each change as its quite often breaking something.

is that "vibium" ? as someone who tried setting up selenium in a workflow im definitely interested.
