The Complete Developer Utility Suite - Free and Private
DailyUtil is a comprehensive collection of free, browser-based developer utilities designed for speed, privacy, and everyday productivity. Every tool in the suite runs entirely in your browser - no data is sent to any server, no account is required, and there are no usage limits. Whether you are a front-end developer formatting JSON responses, a DevOps engineer validating YAML configurations, a security professional inspecting JWT tokens, or a designer picking accessible colour palettes, DailyUtil provides the right tool instantly with zero setup.
Data Format Tools
Working with structured data is a daily reality for every developer. Our JSON Viewer formats, validates, and syntax-highlights JSON payloads from APIs and configuration files. The YAML Viewer handles Kubernetes manifests, Docker Compose files, and CI/CD pipeline configurations with multi-document support. The XML Viewer covers enterprise SOAP services, RSS feeds, and legacy configurations. For comparing any two text blocks, the Diff Checker highlights changes in a clean side-by-side view.
Encoding, Security, and Authentication
Security-sensitive operations deserve tools that never transmit your data. The JWT Decoder parses authentication tokens to inspect claims, verify expiry, and debug OAuth flows - all client-side. The Base64 Encoder handles standard and URL-safe encoding for API headers and data URIs. Generate cryptographically secure credentials with the Password Generator and globally unique identifiers with the UUID Generator. Encode URL parameters safely using the URL Encoder.
Web, Networking, and Content Tools
Debug network infrastructure with the DNS Lookup tool, identify hosting providers with Who's Hosting This, and check your public IP with the IP Address Lookup. Test API endpoints directly in the browser with the API Request Builder. Write and preview documentation with the Markdown Viewer, convert it to professional PDFs using Markdown to PDF, and preview HTML with the HTML Viewer.
