Essential developer utilities and code tools: hash generator (MD5, SHA-1, SHA-256, SHA-512), UUID/GUID generator, SQL formatter and beautifier, cron expression builder with visual interface, HTML minifier, CSS minifier, JavaScript minifier, code beautifier (HTML, CSS, JS), regex tester with real-time matching, Lorem Pixel generator for placeholder images, and typing speed test for developers.
Developer tools are specialized utilities designed for software engineers, web developers, system administrators, and IT professionals to write, test, debug, and optimize code and infrastructure. Our developer tools collection includes JSON formatters with syntax validation and error detection, SQL formatters with query beautification and dialect support, regex testers with real-time pattern matching and capture groups, JWT decoders for token inspection, hash generators for secure password hashing, UUID generators for unique identifiers, barcode generators for product labeling, cron expression builders for job scheduling, and URL shorteners for link management. Whether you're debugging API responses, formatting configuration files, testing regular expressions, analyzing JWT tokens, generating secure hashes, creating scheduled tasks, or managing URLs, our browser-based developer tools provide instant results with privacy-first client-side processing ensuring your code, tokens, and sensitive data never leave your browser. Unlike online IDEs or code playgrounds that require account registration or store your code, our tools are completely anonymous and work entirely offline after the initial page load.

Works seamlessly on Windows, Mac, Linux, iOS, and Android. Any modern browser works perfectly. Consistent experience across all your devices.
Format and validate JSON responses from REST APIs, debug complex nested structures, pretty-print minified code, and test regex patterns against sample text for API integration and data validation.
Format SQL queries for readability, validate syntax before execution, generate hash values for database records, create UUIDs for unique identifiers, and schedule automated database jobs with cron expressions.
Decode and inspect JWT tokens for debugging authentication, generate secure password hashes with MD5 and other algorithms, encode sensitive data in Base64 for safe transmission, and analyze webhook payloads.
Generate unique IDs for database records, create barcodes for inventory management, shorten long URLs for documentation and sharing, and format code examples for technical documentation.
Build cron expressions for automated jobs, validate configuration files, format data transformations between formats, and test patterns for log analysis and data extraction.
Generate unique identifiers for products and users, create scannable barcodes for packaging, manage product URLs for marketing campaigns, and format technical specifications for documentation.
Yes! All developer tools process your code entirely in your browser. No code is sent to servers, stored, or analyzed. Your proprietary algorithms, API keys, and sensitive data remain completely private.
Our tools are language-agnostic. JSON, YAML, XML, SQL, and regex work across all programming languages. Formatters support various dialects and formats commonly used in development.
Yes! All developer tools are 100% free for commercial use with no restrictions. Use them for personal projects, client work, or enterprise applications without licensing concerns.
Enter your regular expression pattern, test against sample text, and see real-time match highlighting with capture group extraction. Perfect for debugging complex patterns without trial and error in your code.
Hash generators create one-way hashes suitable for password storage. However, for production password authentication, use bcrypt, Argon2, or scrypt with proper salting for enhanced security against brute force attacks.
