Stop Pasting Sensitive Data Into Random Online Tools

If you've ever pasted sensitive data into an online tool…

  • pasted a JWT into a random decoder
  • formatted JSON with API keys inside
  • tested regex on production data

…you’ve probably thought:

“this is probably fine”

But is it?


The uncomfortable truth

Most online tools still work like this:

  1. You paste your data
  2. It gets sent to a server
  3. It gets processed there

And you're just… trusting it.

No idea where it goes.
No idea if it’s logged.
No idea who can access it.


The moment it hit me

I was debugging a JWT with user data inside.

Pasted it into a tool.

Then realized:

I have no idea where this just went.

That was enough.


So I built my own tools

I ended up building a set of dev tools that:

  • run entirely in the browser
  • don’t upload anything
  • don’t track anything

👉 https://tooldock.org/


Why this actually matters

This isn’t paranoia.

This is everyday dev stuff:

  • tokens
  • logs
  • internal payloads
  • user data

You don’t always control what ends up in your clipboard.


Example

Let’s say you’re:

  • decoding a JWT
  • formatting JSON
  • testing regex

With most tools:
→ your data leaves your device

With ToolDock:
→ everything stays local


Unexpected benefit

It’s not just privacy.

It’s speed.

  • no network
  • no waiting
  • instant feedback

Once you use client-side tools, everything else feels slow.


What’s inside

Right now there are ~90 tools:

  • JSON Formatter
  • Regex Tester (real-time)
  • UUID Generator
  • Base64 Encode / Decode
  • JWT Decoder
  • Timestamp Converter
  • Hash Generator

Curious

Do you actually care if tools upload your data?

Or is it “meh as long as it works”?

Built this after realizing I had no idea where my data was going 😅

Curious — do you guys actually trust online tools with tokens / logs / JSON?
