Why I built my own browser-based dev tools (and why privacy matters more than I thought)

I've been a developer for years. Like most people, I had a handful of online tools I used daily — JWT decoders, JSON formatters, Base64 encoders. Open a tab, paste, copy, close. Then one day I caught myself pasting a production API token into some random website I'd never heard of. I didn't know who built it. I didn't know where my data went. I just trusted it because it showed up in Google search results. That bothered me enough to build something better. What I built ToolDock is a collection of developer tools that run entirely in your browser. No backend, no accounts, no data sent anywhere. You can verify this yourself — open DevTools Network tab while using any tool and you'll see zero outbound requests with your data. Current tools: JWT Decoder Base64 Encode/Decode JSON Formatter + Validator Regex Tester CRON Expression Parser Color Converter (HEX ↔ RGB ↔ HSL ↔ HSB) UUID Generator, Text Diff, Timestamp Converter and more (19 total) What I learned building it Browser APIs are power
