What this is

A web toolbox gathering the small operations you reach for every day: structured data (JSON / XML / CSV / YAML conversion), text processing, encoding and security (Base64, URL encoding, hashing, symmetric and asymmetric encryption), dates and timestamps, math and unit conversion, developer tools (regex, UUID, JSONPath), network debugging (HTTP, IP, DNS) and image processing.

It is built for developers, testers and ops people who touch these constantly, so the trade-offs are always: correct results, fast interaction, and no login wall.

How it differs from other online tool sites

Most online tool sites work like this: your input is POSTed to their server, computed there, and sent back. That means the production config, keys and customer data you pasted just travelled through someone else's machine.

Here everything is computed in your browser, and no line of code reports your input anywhere. Unplug the network and — apart from the network tools — everything still works. That is not a promise, it is a consequence of the architecture.

Tech stack

Vue 3 + Vite, deployed as static files: no backend, no database, no user system.

PWA support: install it to your desktop or phone home screen and open it offline afterwards.

Bilingual (Chinese / English); the language follows your system setting or the language segment in the URL.

Privacy

Data never leaves the browser: no accounts, no analytics, no ads. See the privacy policy for the full explanation.

Feedback

If something is awkward, you hit a bug, or you want a new tool — feedback is always welcome. Your use cases are what the next tools get built from.
