About Prettify Code: Free Browser-Based Code Formatting Tools

Our Mission

At Prettify Code, we believe that well-formatted, clean code is essential for development productivity and collaboration. Founded on the principle that quality tools should be accessible to everyone, our mission is to provide free, easy-to-use code beautifiers and formatters that help developers maintain consistent coding standards and improve code readability.

We've created a comprehensive suite of code beautifiers, formatters, and validators that process your code entirely in the browser—ensuring your sensitive data never leaves your computer and allowing you to work efficiently without external dependencies or security concerns.

Why Choose Prettify Code?

Privacy-First Approach

Unlike many online formatters, all processing happens locally in your browser—your code is never transmitted to our servers or stored in any database. This zero-data approach makes our tools ideal for working with sensitive codebases or when compliance regulations limit external tool usage.

Always Free

Our tools are completely free to use with no hidden limitations, premium features, or subscription requirements. We believe essential development tools should be accessible to everyone from students to professional teams.

Our Story

Prettify Code was founded in 2025 by a developer who was tired of struggling with poorly formatted API responses and inconsistent code styling across projects. What began as a simple JSON formatter created during a late-night debugging session evolved into a comprehensive toolkit serving developers worldwide.

The initial formatter gained traction in developer communities when users discovered it actually kept their code private, unlike many alternatives that secretly send data to servers. Now, we had expanded our suite to include HTML, CSS, and JavaScript formatters based on user requests.

Today, our open-source tools help over 50,000 monthly developers across 120+ countries maintain consistent code standards and improve team collaboration—all without requiring accounts or subscriptions. We're particularly proud that our tools are used in coding education, helping the next generation of developers learn the importance of clean, readable code.

Technology Stack

Our platform leverages modern web technologies to ensure exceptional performance and user experience:

  • Next.js for fast, SEO-friendly rendering and optimal performance
  • React for a responsive, component-based user interface
  • Monaco Editor (the engine behind VS Code) for a professional code editing experience
  • JavaScript for dynamic functionality and broad compatibility
  • Industry-standard formatting libraries customized for consistent results
  • Service Workers for offline functionality when needed
  • Local Storage for preserving your settings between sessions

All of our code is optimized for minimal bundle size and maximum browser compatibility, ensuring our tools work even on slower connections or less powerful devices.
