Essential tools for developers
Developers need fast and reliable tools for daily tasks. Minifying code for production, formatting malformed code, testing regular expressions, generating harmonious color palettes, and creating visual CSS are common activities that our tools make more efficient.
Code minification and optimization
Minifying CSS and JavaScript removes whitespace, comments, and optimizes code to reduce file size. This results in faster page loading and better performance. Minified files can be up to 60% smaller than their original versions.
Regular expressions (Regex)
Regex is a powerful tool for text search and manipulation, but can be complex to debug. Our regex tester shows matches in real time, capture groups, and includes a library of common patterns (email, URL, CPF, phone) to facilitate your work.
Accessible design with colors
Choosing colors with adequate contrast is not just a matter of aesthetics, but accessibility. WCAG guidelines establish minimum contrast ratios to ensure that people with visual impairments can read content. Our contrast calculator checks if your colors meet WCAG AA and AAA standards.
