Build Guide

Not a coder? You can still make your own fidgit using AI — this guide hands you a ready-to-paste prompt.

Fidgit parameters

Fully self-contained — no external network requests. Games run in a locked-down sandbox that blocks them, so anything trying to phone home just won't work.
Includes an index.html as the entry file.
Runs inside a sandboxed iframe (sandbox="allow-scripts") — no cookies, logins, top-level navigation, or pop-ups.
Allowed files: html, css, js, json, png, jpg, webp, mp3, ogg, wav.
Up to 20 files, 20 MB total, 5 MB per file.

Fill this in and we'll build a custom prompt tuned to your idea. The more detail, the easier the build.

What sort of fidgit is this? — pick any that fit

Does it need any of these features?

Describe your fidgit idea — the more detail, the better

Paste it into Claude Code (recommended) or any AI coder.

Paste the copied prompt into your AI coder (we recommend Claude Code for best results) and let it build.
Iterate! Fidgits rarely come out perfect on the first try — finding problems, adding features, and honing the experience is how you and the AI make it great.
Test, test, test! Make sure everything works before you upload — this is the best way to catch bugs or spot ways to improve it.
Export. Have your AI export all the files your fidgit needs (see the accepted file types and size limits above).

Make a thumbnail. At least 1200×675 px, 16:9 landscape. Skip this and your fidgit's listing will just show its name instead — much less likely to get clicked.
Head to the submit page, fill out the form (name, tagline, description), and tick any features you built in.
Submit for review. This checks your fidgit against the parameters and scans for security threats. If it passes, it's automatically posted to the front page.
