Questions & Answers

As answered by people managing SQLZOO and CertChime.

How would you describe the primary audience of your product?

CertChime's answer:

Independent developers, small teams, and web agencies managing multiple client sites who want simple SSL certificate expiry monitoring without the overhead of enterprise tools.

What makes your product unique?

CertChime's answer:

No sign-up required to check a certificate or set up reminders. Most tools require creating an account before you can do anything useful. CertChime gets out of your way.

Why should a person choose your product over its competitors?

CertChime's answer:

CertChime is built for developers who just want certificate monitoring โ€” not a full infrastructure observability platform. It's lighter, faster to set up, and includes a public status page you can share with clients.

What's the story behind your product?

CertChime's answer:

A certificate expired on one of my services because the cron job monitoring it was running on a server I'd since migrated away from. A user noticed before I did. I looked for a simple tool to prevent this โ€” everything I found required sign-up and came bundled with features I didn't need. So I built CertChime.

Which are the primary technologies used for building your product?

CertChime's answer:

Next.js, React, AWS Lambda, Cloudflare.
