Why some tools have no Save button

Tools handling credentials deliberately cannot write to storage.

Most tools let you save output to the workspace. A few do not, and that is deliberate.

Which ones

  • JWT Decoder and JWT Expiration Checker — tokens are credentials.
  • HMAC Generator — the key you type is a secret.
  • Password Generator and Password Strength — values that should not outlive the tab.
  • API Key Generator — shaped like a credential even though it is not a real one.

What that means in practice

There is no Save button, nothing is written to localStorage or IndexedDB, and the value is not placed in the URL or the page title. Navigating away or closing the tab loses it. Copy what you need before you leave.

The Not stored badge

These tools show a Not stored marker in the status rail so the behaviour is visible rather than assumed. The JWT tool goes further and clears any stray token-like keys it finds in localStorage when it loads.
