Is Scratch Tabs free to use?

Yes, Scratch Tabs is completely free. There are no paid plans, subscriptions, or hidden costs.

Is my data private and secure?

Absolutely. Scratch Tabs is a 100% client-side application. All your data, including tab content, API requests, and JWT secrets, is stored exclusively in your browser's local database (IndexedDB). No data is ever sent to our servers. It's completely private.

Does Scratch Tabs work offline?

Yes, Scratch Tabs is designed to be fully functional offline. Once the application is loaded, all core features—from the text editor to the JWT verifier—work without an internet connection. AI features require a one-time model download but also work offline after that.

A workspace for everything.

The perfect temporary home for JSON, code snippets, cURL commands, stack traces, logs, and more. Instantly recognized, beautifully formatted.

An arsenal of developer tools.

Go beyond text with a suite of 50+ integrated tools. Decode JWTs, test regex, convert JSON, generate passwords, sketch diagrams and more without leaving the application.

Your data, never ours, never theirs.

Everything runs 100% in your browser. Zero tracking. Zero accounts. Zero servers. Just pure, private utility.

The Perfect Companion to Your IDE.

Code snippets, API responses, log files, random JSON blobs—they don't belong in your project files, but you need a place to work with them.

Transform Your Data with Instant Power.

Scratch Tabs allows you to instantly compare, clean, transform, and validate that data before it moves to its final destination.

Setup Steps

Stop Juggling Untitled Tabs

Your daily workflow is filled with temporary data that doesn't belong in your IDE. Stop the context-switching and give that data a proper home.

Without Scratch Tabs...

✗ Polluting your IDE with `Untitled-1.json`, `Untitled-2.json`...
✗ Manually formatting and cleaning messy JSON.
✗ Searching for that one-off script you wrote last week.
✗ Losing focus and productivity with constant app switching.

With Scratch Tabs...

✓ A dedicated space for your temporary data, instantly formatted.
✓ One-click tools to compare, transform, and validate.
✓ Everything is saved locally and searchable.
✓ Stay in the flow with an all-in-one toolkit.

From Chaos to Clarity in One Paste

Your Clipboard

A messy, unformatted JSON string copied from a log file.

"{\"name\":\"John Doe\",\"age\":30,\"isStudent\":false,\"courses\":[{\"id\":1,\"name\":\"History\"},{\"id\":2,\"name\":\"Math\"}]}"

You can't work with this.

Pasted into Scratch Tabs

Automatically unescaped, formatted, and color-coded.

{
  "name": "John Doe",
  "age": 30,
  "isStudent": false,
  "courses": [
    { "id": 1, "name": "History" },
    { "id": 2, "name": "Math" }
  ]
}

Now it's ready for inspection, editing, or transformation.
