Last reviewed: 2026-07-18

When you have a keyboard

Left/right rotate, up thrusts, space fires. Pause with P, mute with M. Touch-only phones are not the target.

When you want a short arcade run

Waves grow from 2 rocks up to 12. Two spare ships. Closing the tab ends the score - there is no localStorage save.

When a tiny download is enough

About 245 KB total, cached after the first load. No network calls after load, no accounts inside the game frame.

When to pick something else

Want a WebGL Underrun run at ~120 KB? Try Retro Arcade Shooter. Want a 3D marble tilt at ~1.7 MB? Use Marble Maze.

Why trust these tools

Ten-plus years of web tooling. The freetoolonline editorial team has shipped browser-based utilities since 2015. The goal has never changed: get you to a working output fast, without an install.
No install, no sign-up. Open a tool and get a working output in seconds - nothing to download and no account to create. Tools that need heavy processing run it on our service, so even a low-powered machine gets the job done.
Analytics stops at the page view. We measure which pages get visited, not what you type or upload inside a tool. There is nothing to sign in to and no profile is attached to your input.
Open-source core components. The processing engines underneath (libheif, libde265, pdf-lib, terser, clean-css, ffmpeg.wasm, and others) are public and audit-able. We link to each one in its tool page's footer.
Free, with or without ads. All tools are fully functional without sign-up. The Disable Ads button in the header is always available if you need a distraction-free run.
