# Browser-Based Developer Tools

Modern developers need **fast, private tools** that run entirely in the browser — no sign-up, no server round-trips, no data leaks.

## Why browser-based tools?

-   Your data never leaves your device
-   Works offline after first load
-   Instant results — no API latency

## Common use cases

Developers use browser tools for [formatting JSON](https://tooldock.org), decoding JWTs, generating UUIDs, and converting between data formats like CSV and JSON.

```js

  const hash = await crypto.subtle.digest('SHA-256', data);
  
```
