Games

Playable browser toys built from your own files and pages. 1 tools

Games here are not the point in themselves — they are what happens when a browser API is pushed past its usual job. A DOM parser meant for reading markup becomes a level generator; a canvas meant for charts becomes a tile renderer; oscillators meant for alerts become a chiptune score.

They run the same way every other tool on this site does: entirely in your tab, with no account, no server-side state, and no telemetry on what you play. Progress and saves live in your own browser storage, and anything you feed them — a page, a file, some pasted markup — is parsed locally and never uploaded.

DOM-Walker

Turn any web page into a playable pixel-art dungeon crawler. DOM-Walker reads a page's HTML structure and converts headings, lists, links and paragraphs into rooms, treasure, portals and enemies — parsed entirely in your browser, with nothing uploaded.

All 1 games, free and without an account

Every tool listed above runs entirely inside your browser. Nothing you open is uploaded, there is no sign-up, no file-size limit, and no watermark on anything you export. Pick a tool to get started, or use the search box at the top of the page to jump straight to one.

Each tool page includes a written guide explaining what the tool does, why it works the way it does, and the mistakes that most often catch people out. Longer walkthroughs live on the blog, and you can read more about who builds these and exactly what data we handle in the privacy policy.
