Intelloidea presents a one-page, document-style summary of One Developer Tools: a free, privacy-focused suite of online developer utilities built to help you format, validate, test, and generate common artifacts without login.
What you can do with One Developer Tools
One Developer Tools includes a JSON Formatter to repair and prettify broken JSON, plus a SQL Formatter to beautify and indent multi-line queries across PostgreSQL, MySQL, SQLite, and more. You can also format XML, clean up HTML, and minify or beautify CSS for faster workflow. Encoding and decoding features cover Base64, URL encoding, and a JWT Decoder that breaks down token parts clearly.
Validation, generation, and utilities
For testing, One Developer Tools offers a Regex Tester with match listings and capture groups, and an in-browser API Tester for basic HTTP requests. Data tools include UUID generation, hashing (MD5/SHA variants), and a mock data generator exportable for database tests. Utility helpers round it out with QR codes, cron parsing, a Markdown editor with preview, color picking, and an offline image compressor.
