Frequently asked questions
Which is better, react or svelte?
Today the two are essentially tied on PopScore (0 vs 0). Both react and svelte are healthy, actively maintained, and worth evaluating on fit rather than headline score.
How is PopScore calculated?
PopScore is a 0-100 score that combines star velocity (35%), fork engagement (20%), activity (25%), mentions (10%), and a noise penalty (10%). See the full formula. The score refreshes several times per day.
How fresh is this comparison?
All numbers are from the most recent sync run (within the last 6 hours). Project metadata (license, language, created date) is from GitHub directly. The verdict is a snapshot — check the live page for the latest.
Can I add a third project to this comparison?
Yes. From any project page, click "Add to compare" to build a 2-5 project list (saved in your browser, no signup). Once you have 2+, the /compare page renders a custom table + radar.
