I created a Labor Calculation Portal (CLT 2025) that is 100% Client-Side (No Backend) and Open Source.

I wanted to share a project I launched this week: Calculy.online. The idea stemmed from a real pain point: most payroll calculators today are slow, full of intrusive ads, and often ask for email/registration just to show a simple result. The Technical Solution: I decided to go against the grain and create a PWA focused on performance and privacy. Zero Backend: All calculation logic (progressive income tax, social security, vacation pay) runs in the user's browser via pure JavaScript. Privacy: Since there's no server-side, salary data never leaves the user's device. Stack: Semantic HTML5 + CSS3 (Grid/Flexbox) + Vanilla JS. The site already has 10 tools (Termination, Net Pay, Vacation, etc.). I would greatly appreciate any feedback on the mobile UX or any bugs in the logic!
