About DevDesk App

We created DevDesk App to solve a simple frustration: online developer tools should be fast, clean, and 100% private.

The problem we experienced every day

As software engineers, we use quick online utilities dozens of times a day — JSON formatters, Base64 decoders, hash generators, and timestamp converters. But almost every existing tool site is cluttered with intrusive video popups, ad banners, and security risks from uploading sensitive text to unknown backend servers.

The security problem is the one that actually mattered to us. Pasting a production connection string into a formatter, or a customer CSV into a converter, means handing that data to a server you know nothing about. Most people do it anyway, because the alternative is writing a throwaway script.

Why we built DevDesk App

We built DevDesk App to create the toolsuite we always wished existed — 300+ utilities executing 100% client-side inside your browser with zero paywalls, zero accounts required, and native hardware speed.

How it works

DevDeskApp is a static site. There is no application server, no database and no user account system, because there is nothing to store. When you open a tool, its code is downloaded once and then runs entirely on your machine — the same way a desktop utility would. Your input stays in browser memory and is discarded when you close the tab. Preferences such as theme and favourites are kept in local storage on your own device.

A practical side effect: the whole site works offline. Install it as a PWA and your tools keep working on a plane, on a locked-down network, or inside an air-gapped environment.

Who it is for

  • Developers and DevOps engineers — encoding, hashing, JWTs, cron expressions, Docker and subnetting.
  • Civil engineers and planners — concrete and rebar quantities, earned value, critical path and productivity.
  • HR and recruitment teams — salary and CTC breakdowns, onboarding checklists and offer letters.
  • Students and everyday users — unit conversion, percentages, dates, image compression and OCR.

How it is funded

A static site is cheap to run, and advertising covers it. That is the whole business model — which is why there is no premium tier, no sign-up wall and no limit on how often you use anything. What we collect and why is set out plainly in our Privacy Policy.

Credits and licence

DevDeskApp began as a fork of the open source IT-Tools project and is distributed under the GNU GPLv3. It is built with Vue 3, Naive UI and UnoCSS, and it stands on a long list of open source libraries.
