What is Roversia?
Roversia is a free, ad-free platform of 39+ browser-based tools — calculators, converters, PDF and image utilities, productivity apps — built with vanilla JavaScript, no frameworks. Everything runs client-side where possible: no forced accounts, no ads, no tracking beyond anonymized analytics. Built and maintained solo. Includes a technical blog with real implementation notes on Firebase, PWA architecture, and browser-based AI (ONNX/Transformers.js).
