Case 09 / 10Privacy-first developer workbench

devdock.dev.

Useful tools. Private by default. Built for flow.

A fast, privacy-first workbench of 90+ utilities for JSON, encoding, text, design, databases, APIs and documents. Everything runs client-side, works offline as a PWA, and is grouped into workflow collections.

01The problem

Pasting a JWT or a customer CSV into a random online tool sends it to someone else’s server.

My roleEverything: tool engine, design system and themes, PWA.

02What I built

  1. 0190+ tools: JSON formatter, cURL builder, hash and JWT tools, colour palettes, CSV ↔ JSON and more.
  2. 02100% client-side computation — nothing is uploaded, nothing is tracked.
  3. 03Workflow collections, favourites and recents; multi-theme architecture including Gruvbox.
  4. 04Offline-capable PWA with a ⌘K command palette.
