Collection

Solve the quick payload job without opening a full IDE tab.

These utilities are for fast technical checks: decoding payloads, generating hashes, creating UUIDs, and cleaning up web-facing strings locally in the browser.

Best for debugging, support triage, QA, and quick launch checks.

What this solves

Choose the right route before you start clicking.

Use the decoder tools when you need to inspect an existing payload.
Use the generators when you need a fresh UUID or password rather than a transform.
Use the URL or Base64 tools when the task is a quick encode/decode rather than a deep debug session.
