DEVRlAN is a privacy-first developer workspace providing practical browser-native tools for common technical tasks. Developers can format and validate JSON, inspect JWTs, encode and decode Base64 and URLs, generate UUIDs, test regular expressions, and use other focused utilities directly in the browser.
DEVRIAN is designed around fast, simple workflows with local processing whenever possible. The goal is to keep everyday developer utilities accessible without unnecessary accounts, installations, or sending sensitive data to third-party services.
WhiteKit brings together 55 developer tools in one place: formatters (JSON, XML, SQL, YAML), converters, security utilities (JWT, hashing, encoding), network calculators, and text tools.
Everything runs 100% client-side. Your data never leaves your device, so you can safely paste API keys, tokens, and production payloads. No sign-up, no upload step, and it keeps working offline once loaded.
Each tool is built to handle real edge cases rather than just the happy path โ the cron parser implements Quartz 6-field semantics correctly, the IPv6 ULA generator follows RFC 4193 Appendix A, and the subnet calculator handles /31 and /32 edge cases.
Devrian.in WhiteKit.devDevrian.in's answer
DEVRlAN combines practical developer utilities with a privacy-first, browser-native approach. Tools such as JSON formatting, JWT debugging, Base64 encoding, UUID generation, regex testing, URL encoding, and hashing can be used directly in the browser, with local processing whenever possible and no account or installation required.
Devrian.in's answer
DEVRlAN is designed for developers who want quick, focused utilities without creating accounts, installing software, or sending sensitive data to unnecessary third-party services. Its browser-native workflow keeps common tasks accessible in one place while prioritizing local processing and simplicity.
Devrian.in's answer
DEVRlAN is primarily built for software developers, engineers, and technical users who regularly need quick utilities for tasks such as JSON formatting, JWT debugging, encoding and decoding, UUID generation, regex testing, URL encoding, and hashing.
Devrian.in's answer
DEVRlAN started as an independent developer project focused on making common technical tasks faster and simpler. The goal is to bring useful browser-native utilities into one focused workspace, while keeping privacy and local processing at the center of the experience. It is being developed based on practical developer needs and feedback.
Devrian.in's answer
DEVRlAN is built with Next.js and React using TypeScript. The interface uses Tailwind CSS with CSS variables for the design system, while Framer Motion handles complex UI motion and lucide-react provides the icon system.
Devrian.in's answer
DEVRlAN is currently an independent developer project and does not have publicly disclosed major customers. The product is available for developers and technical users to use directly.
