As answered by people managing WhosOff and Cert Decoder.
WhosOff's answer
WhosOff is built as a cloud-based Software-as-a-Service (SaaS) platform, utilising a comprehensive web portal and native iOS and Android mobile applications.
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
WhosOff's answer
WhosOff stands out by combining comprehensive holiday booking, TOIL tracking, and automated sick leave management into a single cloud-based system. Unlike many competitors, it features transparent, no-commitment pricing, full-featured mobile apps, and UK-specific HR compliance, all backed by an up to 8-week free trial.
WhosOff's answer
A person or business should choose WhosOff over competitors because it offers a specialised, budget-friendly absence management system tailored to UK HR practices. It features transparent pricing starting from £1.75 per user/month, a generous 8-week free trial, and no lock-in contracts.

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.

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
