BrowseThe modern web development workflow involves dozens of repetitive utility tasks - formatting JSON, encoding and decoding strings, generating hashes, testing regular expressions, compressing images, and manipulating files. Developer tools collections have evolved from individual command-line scripts in the 1990s to comprehensive browser-based utility platforms that require no installation. India's software developer population crossed 5.8 million in 2023, making it the second-largest in the world after the United States, creating enormous demand for productivity tools that streamline daily development work.
This dev tools hub provides 78 free utilities covering the complete development workflow. Data tools include a JSON formatter, Base64 encoder/decoder, hash generator (MD5, SHA-1, SHA-256), UUID v4 generator, and regex tester. Web tools include QR code and barcode generators, CSS gradient generators, and code beautifiers and minifiers for HTML, CSS, and JavaScript. AI tools include a token counter for Claude and GPT models. Infrastructure tools include DNS lookup, WHOIS lookup, and SSL certificate checker. All tools run in the browser with no login required.
Indian developers working at product companies, software service firms, and early-stage startups across Bengaluru, Hyderabad, Pune, and Chennai frequently switch between multiple utility websites during their workday. Centralising these tools in one trusted platform reduces context-switching overhead and keeps sensitive data (such as API keys being Base64-encoded or hashed) processed locally rather than sent to unknown third-party servers. The PDF and image tools are particularly valuable for backend engineers integrating document processing pipelines in India's fast-growing fintech, edtech, and logistics technology sectors.
