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.
AppErgo is an independent project covering text, codes and puzzles, conversion, dates and time, audio, games, random generators and everyday utilities. Each tool is designed for quick use on desktop and mobile, with a clear interface and a responsive layout.
Available in English and French, AppErgo is built primarily with static HTML, CSS and vanilla JavaScript. Its name combines App with Ergo, reflecting a focus on practical applications, ergonomics and ease of use.
