Plinkr is a free collection of small online tools you can use directly in your browser. No accounts, no signups, no friction — open the tool, use it, close the tab.
Why we built it
The web is full of utility sites that ask too much. They want your email to flip a coin. They want your account to count words. They want cookies just to run a stopwatch. We thought there should be a place where the basics are just there, instantly, with no setup. So we built one.
How it works
Every Plinkr tool runs entirely in your browser. The text you paste, the numbers you type, the dates you enter — none of it leaves your device. There is no server processing because there is no server doing anything beyond serving the static page that loads the tool.
That means: tools work the same way on a phone, tablet, or laptop. Once a tool is loaded, it can keep working even with a flaky connection. And we genuinely cannot see what you do — your data stays where it started.
What's here today
A growing set of small utilities — random pickers, timers, text helpers, decision tools. More are coming as we hear what people search for and what gets used. If a tool you want isn't here, drop us a line at [email protected] — we read every message.
Privacy and ads
We use Cloudflare Web Analytics for anonymous, cookieless visit metrics — no personal data, no tracking. To keep the tools free, we may show ads via Google AdSense, which uses cookies for ad relevance. You can opt out at any time. Full details in our Privacy Policy.
How it's built
Plinkr is built with Next.js, Tailwind CSS, and TypeScript. The whole site is statically generated and served from Cloudflare's global edge network — fast everywhere, no server lag, indistinguishable from a static HTML site even though it's a real React application underneath.
