Developer tools

Format, parse, encode, decode, and generate common dev assets.

Developer tools workflow

Use these tools when you need to inspect data, transform text, or create small dev assets during debugging. They are built for quick checks inside the browser, so you can move from a log, ticket, API response, or config snippet to a clean result without setting up a new project.

Most developer tools run fully on this device. That makes them a good fit for draft payloads, test tokens, sample data, and other snippets that should not be pasted into a random hosted utility.

  • Format JSON before sharing a clear bug report.
  • Decode Base64, URLs, and JWT payloads for inspection.
  • Generate UUIDs, hashes, colors, and passwords without an account.
