A developer's day is full of small jobs that do not deserve a project: make an id, tidy a blob of JSON, check whether a string is really a UUID, turn a config file into another format. Each one takes a minute if you have the right tool open and ten if you have to find one. mybittools.com is an attempt to be the drawer you reach for, with every tool built the same way so you never have to think about which one is safe to paste into.
The rules every tool follows
- One job each. The UUID generator generates UUIDs. The JSON formatter formats JSON. A page that tries to do everything is slow to load and hard to trust. A page that does one thing can be fast, obvious and finished.
- It runs in your browser. Nothing you type or paste is sent to our server, logged or stored. Every tool uses the browser's own capabilities or a small open source library bundled into the page. You can verify it in the network tab, and we say so on each page because it is the single most important property of a tool you paste real data into.
- No account, no limits that matter. No sign up, no email, no paywall, no "upgrade to copy more". The site is paid for by a small number of ads.
- It loads before you finish reaching for the mouse. Plain HTML, CSS and JavaScript, no framework, no fonts to download, no tracking beyond basic analytics. Pages are tens of kilobytes.
- It explains the concept. Under every tool is a guide to the thing it deals with, written for the person who landed there with a question. The generator page explains what a UUID is and which version to pick. The formatter explains why JSON breaks. If you only wanted the tool, scroll past. If you wanted to understand, it is there.
What is in the box today
- UUID generator. Every version from v1 to v7, up to 1000 at a time, with uppercase, braces, no hyphen, quotes and Base64 formats and download as text, JSON or CSV. Plus a validator and decoder, a page for each version and a page for each of ten languages and databases. The full story is in Inside our UUID generator.
- JSON formatter and validator. Format with your indent, validate with line and column, minify, sort keys. The details are in Inside our JSON formatter.
- The blog. Guides to UUIDs and JSON that go deeper than the tool pages, an AI basics course that builds up from zero, and hands on posts about the AI tools developers use now. Every post links to the tool it relates to, and every tool links to the posts behind it.
How the tools connect
A toolbox is more useful than a pile of tools because things sit next to each other. Format a JSON response, then paste the id you found into the UUID validator to see when it was created. Read why v7 is better for primary keys, then generate a batch on the v7 page. Learn how tokens work in the AI series, then minify a document in the formatter and see how much shorter it gets. The pages are built to hand off to each other, and the guides are written to point at the tool that answers the question.
What is coming
- JSON visualizer. Draws a document as a diagram you can pan and zoom, with a Mermaid export for docs and pull requests. The VS Code extension comes first, then the web version. Here is the plan.
- JSON converters. To CSV, to YAML, to TypeScript types. Same rules: one job, in your browser, free.
- UUID extras. A collision calculator and larger bulk exports.
Ask for a tool
The tools here exist because someone needed them during a working day. If there is a small utility you keep looking for, describe what it should take in and what it should give back on the contact page. Simple, focused ideas are the ones most likely to get built.
