As answered by people managing CertChime and AppWrite.
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.
