As answered by people managing Toolmate.io and Eloquent JavaScript.
Toolmate.io's answer
toolmate is a fast, ad-light collection of browser tools focused on gamers — a click speed test (CPS), reaction time test, and eDPI/sensitivity calculators in one place. Everything runs locally in the browser with no signup and no install, unlike the ad-heavy single-purpose sites these tools usually live on.
Toolmate.io's answer
Most CPS or sensitivity tools are single-purpose pages buried in ads. toolmate bundles the tools gamers actually use side by side, keeps the interface clean and ad-light, and runs entirely in the browser — no account, nothing to install. You can also embed the tools on your own site for free.
Toolmate.io's answer
Gamers and PC enthusiasts — especially FPS players tuning their mouse sensitivity (eDPI, cm/360) and click speed, plus anyone who wants a quick way to test their mouse, keyboard, mic, or webcam in the browser.
Toolmate.io's answer
toolmate is built by dearnode. The idea was simple: the small tools gamers reach for — click speed tests, sensitivity calculators, device checks — are almost always slow, ad-cluttered, single-purpose pages. toolmate puts the good ones together in one clean, fast, ad-light place that runs entirely in the browser.
Toolmate.io's answer
toolmate is a static site built with Astro, runs entirely client-side in the browser (no backend for the tools themselves), and is hosted on Cloudflare. It uses standard web APIs so everything works without installs or accounts.

Seconded. I won't recommend it and no one I know has recommended it for a decade. It's hard for someone who doesn't know JS to know which parts has changed and is no longer the way to do things. https://github.com/getify/You-Dont-Know-JS... - Source: Hacker News / about 2 years ago
