As answered by people managing JavaScript and CertChime.
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.
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.
CertChime's answer:
CertChime is built for developers who just want certificate monitoring — not a full infrastructure observability platform. It's lighter, faster to set up, and includes a public status page you can share with clients.
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 — everything I found required sign-up and came bundled with features I didn't need. So I built CertChime.
CertChime's answer:
Next.js, React, AWS Lambda, Cloudflare.
