I Caught a Dev Tool Stealing My Data — So I Built 7 Alternatives That Make Zero Network Calls

DevToolBox — 7 developer utilities, zero network requests

Last month I was debugging an API integration and pasted a response containing auth tokens into a popular online JSON formatter.

Out of habit, I had DevTools open. I watched it fire off a POST request to some analytics endpoint — with my pasted content in the body.

That was my wake-up call. These "free tools" aren't free. You're paying with your data.

So I Built My Own

DevToolBox — 7 developer utilities where the processing is verifiably client-side.

Not "trust us, we don't store it." Actually zero network calls. Open your Network tab while using any tool. Nothing fires.

Live:

Open DevTools → Network tab → use any tool → verify zero requests yourself.

What dev tool do you use where you've wondered "where does my data go?" I'll build a zero-trust version of whatever gets the most engagement here.
