# PlayApp

> PlayApp is a marketplace of mini web utilities — small, single-page tools (calculators, generators, games, converters, design tools and more) that anyone can publish with one shareable link and anyone can use for free.

PlayApp lets creators upload a ZIP containing an index.html, or a single HTML file, and instantly get a permanent, shareable URL. Listed utilities appear in a public, categorized catalog. It is aimed at indie makers, no-code enthusiasts, students learning HTML and JavaScript, designers, and people building little tools with AI. It is intentionally not a general hosting platform: every app is static, client-side code with no server-side runtime.
