Roversia
39+ free browser tools. No ads, no tracking, no signup.
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).
Hey Product Hunt 👋
I built Roversia solo over the past few months — it's a collection of 39+ free tools I kept needing myself (PDF editing, percentage calculators, timezone converters, image compression, background removal running fully in-browser via ONNX) plus a few PWA apps and card games.
No ads, no paywalls, no accounts forced on you. Everything client-side where technically possible.
Would love feedback on which tools are most useful and what's missing. Happy to answer anything about the stack (vanilla JS, Firebase, Netlify Functions) too.
