If you've ever needed a quick JSON formatter, regex tester, or password generator and didn't want to install anything or sign up for yet another account — I built something for that.
UniversalTools.org is a free collection of 59+ browser-based tools for developers and everyday users. No signup, no paywall, no ads blocking the actual tool. It also works in 7 languages (English, Thai, Indonesian, Vietnamese, Spanish, Portuguese, Japanese).
A few tools developers use most:
- JSON Formatter — validate and beautify JSON instantly
- Regex Tester — test patterns against sample text with live highlighting
- JWT Decoder — decode tokens without pasting them into a random site
- Base64 Encoder/Decoder — quick encode/decode in the browser
- Hash Generator — MD5, SHA256, and more
- Cron Job Scheduler — build and validate cron expressions
- HTTP Status Codes Reference — searchable list with meanings
There are also everyday utilities like a BMI calculator, loan calculator, currency converter, and unit converter for people who just need a quick answer without the SEO-stuffed blog post that usually comes with it.
Everything runs client-side where possible, so it's fast and there's nothing to install.
