A Tour of Frabs' Small Everyday Developer Utilities

Not every task needs a full application. Plenty of everyday development work is a five second detour: generate an ID, sanity check a password, confirm a regular expression actually matches what it should. Keeping a set of small, single-purpose tools on hand for exactly these moments saves reaching for a script, a REPL, or a half-remembered command every time one comes up.

UUID Generator produces random version 4 UUIDs for database records, temporary file names or request IDs, entirely in your browser using its cryptographically secure random number generator. Password Generator uses the same underlying randomness to build a password from whichever character types you choose, for the moments a password manager's own generator isn't within reach.

Password Strength Checker estimates the entropy of a password you type, checked locally and never sent anywhere. JWT Decoder splits a JSON Web Token into its header and payload and renders both as formatted JSON, useful for inspecting a token from an API you're integrating with without writing a single line of code to do it.

Regex Tester runs a pattern against a block of text and highlights every match, letting a regular expression be built up and checked in small steps rather than guessed at blind. Cron Expression Explainer takes the five field syntax used to schedule recurring jobs and describes in plain English exactly when it will run, worth pasting a schedule into before it ships to production.

Color Converter takes a color in HEX or RGB and shows it in all three common formats with a live preview, handy when a design tool and a codebase disagree on which one to use. Lorem Ipsum Generator fills a layout with placeholder text before real copy exists, so a mockup can be judged on its own structure rather than on whatever text happens to be sitting in it.

QR Code Generator turns a URL or block of text into a scannable code for printed material or signage. Favicon Checker looks for a site's declared icon and confirms it actually loads, a small detail that's easy to miss after a redesign but noticeable the moment it's wrong.
