Built by gamers, for every gamer.
Zarynx exists because free, fast, no-nonsense gaming tools shouldn't be hard to find. No sign-ups, no paywalls — just the tools you actually need.
Our mission
Gaming tools that respect your time.
We started Zarynx after getting fed up with bloated gaming sites that hide tools behind paywalls or drown you in ads. Every tool we build is free, loads instantly, and requires zero account creation.
Always free
Core tools will never go behind a paywall. We may add optional extras, but the essentials stay free forever.
Privacy first
Tool inputs run entirely in your browser. We don't collect what you type, and we never sell data.
Accurate data
Results are based on real benchmark data and community-sourced hardware info, updated regularly.
No clutter
Fast pages, clean UI. We cut the noise so you can get your answer and get back to gaming.
How we got here
A short timeline.
Early 2024
The idea
Frustrated by inaccurate bottleneck checkers hidden behind ads, we built our own PC Bottleneck Calculator over a weekend.
Mid 2024
First tools launched
Sensitivity Converter and Reaction Speed Test followed. Word spread on Reddit and Discord — we realised there was real demand.
Late 2024
Zarynx goes live
We packaged everything under one roof — tools, tier lists, and blog guides. The site launched publicly with 10 tools.
Today
22+ tools and growing
New tools ship regularly based on community requests. The goal hasn't changed — the fastest free gaming tools on the web.
