About
Hyperuranium is a small library of single-purpose tools that run entirely inside your browser. Nothing uploads. Nothing tracks you. Nothing asks you to sign up or sign in. When you close the tab, it's gone.
Tools live at /tools. They are small — one screen, one purpose — and they all work without a server unless the tool's purpose specifically requires one. When a tool does need a server, it gets a Class II badge and a plain-language note about what leaves your browser and why.
Posts live at /posts. They explain the tools, the techniques behind them, and the occasional digression about why a thing is built this way.
The forum lives at /forum. Anyone can post under any name; no accounts, no captchas, no algorithms deciding what you see. The order is reverse-chronological because that's the only order that doesn't lie to you.
Most utilities you find online are funded by collecting you. A JPEG compressor wants your email. A color picker wants your Google account. A PDF tool wants $9 a month forever. The actual program runs in your browser anyway. The accounts are the product.
There's no good reason for that to be the default. So this is the alternative.
Built and maintained by one person, with help from the people who post on the forum. If you have a tool you wish existed, say so — the forum is the way in.
