- The feature catalogue and weights come from Can I Use and MDN browser-compatibility data, refreshed as browsers ship.
- Scores separate stable features from experimental ones, with the raw percentage available alongside the weighted score.
- The maker’s build-week post says the core app was created and deployed with Claude Code in about a day.
