About DevTools Pro

Our Mission

DevTools Pro was built with a simple goal: provide developers with fast, free, and private code formatting tools. No sign-ups, no data collection, no limitations.

How It Works

Unlike many online formatters, everything happens in your browser. When you paste code and click Format, the processing is done by JavaScript running locally on your device. Your code never leaves your computer.

• JSON: Native JSON.parse + JSON.stringify
• HTML & CSS: js-beautify library (open-source)
• SQL: Custom built-in SQL formatter
• XML: Custom DOM-based formatter
