Fast tools and focused guides that do one job well.
NeonStack is a small library of private, lightweight calculators, comparison guides, and game helpers built to run directly in your browser.
Private by default
Every tool on NeonStack runs entirely in your browser. Nothing you type into a calculator, converter or text utility is uploaded anywhere — there is no account step, no sign-up wall, and no tracking behind the form. Open the page, paste your text, get the answer.
Reviews that answer one question
The review pages compare specific purchases: which tier is worth paying for, what the free plan quietly limits, and where a tool breaks down once you use it every day. Each guide ends with a short recommendation instead of a ten-way tie.
Second-screen helpers for games
The game helpers cover the quick lookups you need mid-match — build orders, map references, calculators and checklists — built to load fast on a phone and stay out of the way.
