Built differently

Less friction. More work done.

No dashboards, no onboarding, no upsell. Just small tools that open fast and keep your data where it belongs.

Private by construction

Every operation runs in your browser. Inputs never touch a server, because there is no server to touch.

Keyboard first, mouse friendly

Press ⌘K or Ctrl K anywhere to jump between tools. Copy buttons, samples and clear states are always one key away.

Static, fast, offline

Prerendered HTML, hand-written JavaScript, self-hosted fonts and an offline cache. No framework hydration and no layout shift before you start typing.

FAQ

Good to know

How privacy works

Are the tools really free?

Yes. No account, no trial, no credit card. The site is a static project and costs almost nothing to run.

Do you collect or store my data?

No. Tool inputs are processed in the browser and never sent anywhere. There is no analytics script. Theme and recent-tool preferences stay in localStorage on your device.

Can I use the generated output commercially?

Yes. UUIDs, hashes, formatted JSON, code and text you produce are yours. There is no license attached to the output.

Do the tools work offline?

Yes, after the first visit. The app shell and pages you have opened are cached locally, so they reopen offline. A tool you have never opened still needs a connection the first time.

How is this different from other online toolboxes?

Most tool directories are ad-supported, send inputs to a server, or are English-only. This one is static, bilingual and keeps inputs in the browser, and it keeps working offline after the first visit. The trade-off is 40 focused tools instead of hundreds.
