Oh Dear!'s answer
Cert Decoder's answer:
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
Oh Dear!'s answer
Oh Dear monitors the health of the entire website, not only whether a single URL responds. Oh Dear monitors uptime, SSL certificates, DNS records, domain expiration, scheduled tasks, broken links, mixed content, Lighthouse performance, APIs and application health. Oh Dear also gives teams one dashboard for every website they manage.
Oh Dear!'s answer
Oh Dear is a strong fit for teams that manage multiple websites and want to find problems before clients or visitors report them. Every plan includes every monitoring feature, so teams can monitor website availability, technical health and content quality without assembling several separate tools. Broader observability platforms remain better suited to infrastructure telemetry, logs, traces and application performance monitoring.
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.
Oh Dear!'s answer
Oh Dear is built for developers, technical leads, DevOps teams and CTOs responsible for one or more websites. Oh Dear is especially useful for teams managing client websites, website portfolios, recurring reports and incident communication.

For web-application monitoring, we’ve [1] gone the approach of outside-in monitoring. There’s many approaches to monitoring and depending on your role in a team, you might care more about the individual health of each server, or the application as a whole, independent of its underlying (virtual) hardware. For web applications for instance, we care about uptime & performance, tls certificates, dns changes, crawled... - Source: Hacker News / about 2 years ago
