About UUIDly
Last updated: May 9, 2026
UUIDly is a free, browser-based tool for generating cryptographically secure UUID v4 identifiers. It exists because every developer eventually needs a quick UUID — for a database row, a file name, a session token, a test fixture — and most online generators are slow, ad-cluttered, or worryingly opaque about where the random bits come from.
What we do differently
- Client-side only. UUIDs are generated in your browser using the Web Crypto API (
crypto.randomUUID()). Nothing is transmitted to our servers — there are no UUIDs on our servers. - Fast. The page is a single static HTML file. No tracking pixels, no slow analytics blocking the render.
- Open about how it works. Right-click → View Source. The entire generator is a few lines of JavaScript.
- Educational. The FAQ and code examples are there to help you understand UUIDs, not just consume them.
Who runs this site
UUIDly is built and maintained by Binay Kumar Gupta, a software engineer and graduate of IIIT Allahabad. The site started as a small weekend project to scratch a personal itch — needing a clean, ad-free UUID generator — and grew into something other developers could rely on.

How we keep the lights on
The site may display advertisements (via Google AdSense or similar networks) to cover hosting costs. Ads — when present — are clearly labeled as "Advertisement" and are kept away from the generator itself so they never interfere with your workflow. We do not sell user data and we do not collect personal information beyond standard server logs.
Tech stack
Pure HTML, CSS, and vanilla JavaScript. No frameworks. No build step. The whole site weighs less than a single screenshot.
