devbench is a set of small developer tools, each paired with a short reference — the kind of notes you would keep in a manual next to your keyboard.
Ground rules
- Everything runs in your browser. JSON, SQL, tokens and text you paste are not sent to a server.
- Where a tool follows a standard (RFC 8259 for JSON, RFC 4648 for Base64, RFC 7519 for JWT, RFC 9562 for UUIDs), we link it.
- No sign-up, no paywall.
