Developer Tools
Every developer needs a reliable toolkit for the tasks that interrupt your flow: formatting messy JSON, encoding strings for URLs, debugging regex patterns, or converting between data formats. Our collection of 50+ developer tools handles the routine operations that would otherwise require installing dependencies, writing throwaway scripts, or searching through documentation. From code formatters that beautify or minify your JavaScript, CSS, and SQL to encoding utilities for Base64, URL encoding, and hash generation, these browser-based tools work instantly without setup. Network utilities help diagnose connectivity issues, decode SSL certificates, and generate configuration files. Whether you're debugging an API response, preparing data for transmission, or configuring server settings, these tools eliminate friction from your development workflow.

Working with API responses? The JSON Formatter beautifies and validates JSON data. Convert responses to other formats with the Data Converters or decode JWT tokens with the JWT Decoder.
Preparing data for transmission? Use the Base64 Encoder for binary data, the URL Encoder for query parameters, or the HTML Entity Encoder for web content.
Debugging or optimizing code? The Diff Checker compares code versions, the Regex Tester validates patterns, and minifiers compress your JavaScript and CSS for production.
Configuring servers? Generate scheduled tasks with the Cron Expression Generator, create access rules with the .htaccess Generator, or verify SSL certificates with the SSL Certificate Decoder.
