Side-by-side comparison of two listed Dev Tools — real listing data only, no paid placement.
On record, they differ in: pricing (Astro Free vs CodeSandbox Freemium); unique tags (Astro 3: #framework #static-sites #open-source vs CodeSandbox 3: #sandbox #prototyping #code-review); category rank (Astro #4 vs CodeSandbox #8). Same category (Dev Tools). Listing facts only — not a recommendation.
Web framework for content-driven sites that ship zero JS by default
Astro renders pages to static HTML and hydrates only the interactive islands, so content sites stay fast. It supports React, Vue, Svelte and friends side-by-side, plus a content layer and view transitions. Free and open source.
