Cert Decoder
toolmate.io is a free, privacy-friendly suite of browser tools for gamers and PC enthusiasts. Measure your click speed (CPS test), test your reaction time, calculate your eDPI and cm/360 sensitivity, and check your mouse, keyboard, and microphone. No account, nothing to install. Made by dearnode.
Cert Decoder is a free online tool that helps you decode X.509 SSL/TLS certificates in PEM format. It instantly shows important information like the issuer, expiry date, SAN entries, and fingerprint. All data is processed locally in your browser, so nothing is ever sent or stored elsewhere.
Toolmate.ioToolmate.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.
Cert Decoder's answer:
I built certdecoder.com over the weekend for my own needs. Sometimes in my work, I need to verify and check certificate details.
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.
Cert Decoder's answer:
certdecoder.com was built using just JavaScript and HTML—simple, fast, and with all processing happening locally in your browser, so no certificate data is sent to any server
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.
Cert Decoder's answer:
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
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.
Cert Decoder's answer:
Simple, fast, and reliable. Some similar tools can’t even decode basic certificates. I rigorously tested my tool with many real-world certificates and covered several edge cases where competitors fall short.

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.

Why? Because I built certdecoder.com and couldn’t find a decent place to submit it. So I said screw it — I’ll build my own. With blackjack and hookers. - Source: dev.to / over 1 year ago
