There is no AI JavaScript generator on this site.

This URL used to look like a product. It had a text box that could not be typed in, a dark panel showing a snippet of code that a human had typed into the template, and three quotes attributed to job titles instead of people. Those people do not exist; the snippet was not generated by anything.

On 2026-08-27 we deleted the pretence. No model was ever called — not ours, not a third party’s. Anyone who pressed the button would have received nothing, and the structured data on the page was telling search engines and AI assistants that they would get “production-ready code in seconds, 100% free, no registration”.

Why we did not just wire up a model

Because it would cancel the only reason this domain is worth anything. Everything here runs inside your browser: the Wi-Fi password you encode into a QR code, the vCard directory, the invoice figures, the seed you used for a token — none of it goes anywhere, because there is no server call to go to. A prompt-→code box is the opposite transaction, and once you are a wrapper over somebody’s API, the moat is a weekend of somebody else’s work.

If this page ever changes, it changes with those two things stated on the page: what leaves your machine, and what we verify before showing you the result.

What is actually here

Six working tools. They run offline after load, they do not store anything, and where the output can be checked, it is checked by a machine rather than promised by us — the QR payload builder and its round-trip suite, for instance, is the reason this site now says 2,953 bytes and not the 4,296 quoted all over the web.

• QR code generator →

  Wi-Fi, vCard, email, SMS, URL, text — shows the exact encoded string, then PNG or SVG. Payload formats are checked by an encode → decode → byte-compare suite.

• QR code with logo →

  Logo overlay sized in symbol modules, coverage meter against the error-correction budget, print-size check, batch CSV to A4 labels.

• UUID v4 and v7 →

  Single or batch, copy or export, with the browser and Node.js calls next to it.

• Random numbers →

  Ranges, decimals, duplicate control, and `Math.random` against `crypto.getRandomValues`.

• Random strings →

  Passwords, API keys, tokens, fixtures — with the entropy shown.

• Invoice generator →

  Build an invoice and export a PDF, in the browser.

If you came here wanting code written for you

The honest answer is that a coding agent is the right tool and a website text box is not. What we can do is hand you the part that never goes stale: the exact API call, the exact payload format, the escape rules — on the pages above and in the guides, with runnable code you can paste.
