Developer Tools

Data, formatted

The JSON formatter pretty-prints minified JSON into readable, indented structure — and validates it, pointing at exactly where a missing comma or bracket broke things. One click minifies it back down for shipping. If you work with APIs, this is the tool you'll open ten times a day: paste the response, read it like a human, copy the fixed version.

The Base64 encoder/decoder converts text to Base64 and back. Base64 shows up everywhere — data URIs, API tokens, email attachments, config blobs — and when you need to see what's inside one (or produce one), this does it without a terminal. The binary/hex converter translates between binary, octal, decimal, and hexadecimal live as you type, which is handy for low-level debugging, subnet math, color values, and coursework.

IDs on demand

The UUID generator produces random UUID v4 identifiers — one at a time or a whole batch. UUIDs are the standard way to create unique IDs without a central authority: database keys, request IDs, test fixtures, filenames that must never collide. Version 4 UUIDs use cryptographic randomness, so the chance of a duplicate is effectively zero.

One caution that applies to this whole category: these tools run locally in your browser, which is great for privacy — but don't paste live production secrets, private keys, or real user data into any web tool, ours included. For routine development work, though, everything here is fast, free, and forgetful: nothing is logged.
