# Runs on any screen with a browser.

- **Desktop, phone, tablet.** Nothing to install for players. Your game declares what it supports on each screen: full, playable or not supported, and the store page says so.
- **Installable.** Every game can be installed from the browser, with its own name, icon and orientation.
- **Isolated.** A game runs in a sandboxed frame on play.cassette.gg, apart from cassette.gg.
- **Cached at the edge.** Builds are cached on Cloudflare’s network and served from the edge.
- **Engines.** Unity WebGL, Godot 4 (single-threaded), Construct, GameMaker, Phaser, PixiJS, three.js and plain JavaScript.
