What is Astro?

Astro ships zero JS by default. But fixing island styles is still manual.

Astro's islands architecture delivers exceptional performance, but debugging styles across framework islands, scoped CSS, and content collections means constantly switching between templates and browser DevTools.

PulseDev vs. the old way

How Astro developers fix UI issues — before and after PulseDev.

~30min

Legacy island fix

~2min

With PulseDev

Click any element — even inside a React or Vue island. PulseDev resolves the source file and writes the fix.

15x
