JWT Decoder & Generator

JSON Web Tokens are widely utilized for stateless session authentication across microservice meshes. However, developers frequently treat them as encrypted objects when they are merely encoded string payloads. Anyone who intercepts a JWT can read your claims array. This utility allows you to instantly inspect claims (like expiration dates (`exp`), issuers (`iss`), and subject attributes (`sub`)) locally without exposing internal authorization keys to the open internet.

Regex Tester & Explainer

Regular expressions are powerful but notorious for introducing invisible runtime traps like catastrophic backtracking, which occurs when nested quantifiers cause an exponential evaluation path that freezes browser tabs. Using a visual, responsive tester allows you to safely construct complex regex constraints, evaluate boundary matches, and inspect capture group indexing side-by-side before committing patterns to production codebases.

Offline Password Entropy & Strength Tester

CSS Generators Toolkit

The CSS Generators Toolkit is a comprehensive visual sandbox for front-end designers and developers aiming to craft modern UI elements without writing complex syntax by hand. Crafting smooth multi-layered box shadows, responsive linear gradients, and buttery keyframe animations requires tedious trial and error in a code editor. This toolkit replaces that manual labor with an intuitive, slide-controlled graphical interface. Adjust blur radius, color opacity, and spread values for shadows, or dictate the exact degree angle for CSS gradients, and instantly watch the preview element update in real-time. Once your design is perfected, the tool automatically compiles the optimized, cross-browser compatible CSS rules—including necessary vendor prefixes—ready to be copied and pasted directly into your project.
