Show HN: I worked on a new browser for 2 years, today it passed Acid 3

A lone developer just walked into one of tech’s most intimidating arenas and declared: I built a whole new web browser from scratch in two years, and it now hits a perfect 100/100 on Acid3 — an old but famous browser test once used as a bragging-rights scoreboard. He says it’s tiny, speedy, and even about twice as fast as Chrome in early tests. For browser nerds, that’s a mic-drop moment. For the comment section? It was blood in the water.

The biggest split was classic internet energy: “huge achievement” vs “show me the receipts.” One supportive commenter called it a massive win for a solo creator and said they’d love to see a fully open alternative take on the giant corporate browsers. But skeptics were already circling. One immediately side-eyed the project’s polished writing and other products on the site, basically asking: was this really “hand-written,” or was AI doing some of the work? Another cut right to the numbers and demanded a Speedometer 3.1 score — because in tech comments, if you claim you’re faster than Chrome, people want a stopwatch, a spreadsheet, and maybe a courtroom exhibit.

Then came the nitpick heard round the thread: does scoring 100 on Acid3 even matter in 2026? One commenter pointed out that modern major browsers don’t necessarily pass it anymore because the web has moved on. Translation: the celebration was real, but the crowd still turned it into a debate club. Bonus wildcard? Someone didn’t care about the standards drama at all — they just wanted the browser to be “agent friendly,” which is such a 2026 comment it practically came pre-memed.
