SSL certificate and domain expiry monitoring you own forever.
Developers rent API docs, monitoring, secrets and webhook plumbing by the month for side projects that earn nothing yet. Self-hosted pay-once utilities cost less than one month of the SaaS they replace.
The tool this job usually means renting is SSLMate-style SSL monitors, at $10–20/mo — roughly $180 a year, every year. Certwatch does the job for a one-time $24 — running on infrastructure you control.
Green over 30 days, yellow at 30 or under, red under 7 days, or for expired, invalid or unreachable hosts.
For developers, traffic-light dashboard pays off while you're shipping, not managing vendor accounts — and it's covered by the same one-time $24, not metered per month.
Node tls checks expiry, issuer, SAN list, chain validity, self-signed certs and weak keys (RSA under 2048, EC under 224).
For developers, real TLS handshake checks pays off while you're shipping, not managing vendor accounts — and it's covered by the same one-time $24, not metered per month.
Best-effort registry lookups so the domain registration itself does not lapse either.
For developers, domain WHOIS expiry pays off while you're shipping, not managing vendor accounts — and it's covered by the same one-time $24, not metered per month.
One payment of $24 gets you the packaged 1-click installer, or clone the MIT source at github.com/bensblueprints/ssl-cert-monitor-mvp and run it yourself for free.
docker compose up on a $5 VPS that can reach your hosts, or run the Electron desktop build, adding SMTP credentials to .env if you want email alerts.
Point it at the sites you care about; it runs real TLS handshakes on a schedule and pages you before anything expires.
Certwatch is $24, once. SSLMate-style SSL monitors at $10–20/mo — roughly $180 a year, every year. Two months of a paid SSL monitor covers Certwatch, and one cert it saves from expiring covers the 2am page it would have cost you.
Two months of a paid SSL monitor covers Certwatch, and one cert it saves from expiring covers the 2am page it would have cost you. Certwatch costs $24 once; SSLMate-style SSL monitors charges $10–20/mo — about $180 a year. For developers, that fixed cost is the whole point: the tool is a one-time line item, not a monthly one.
Yes. Certwatch is MIT-licensed at github.com/bensblueprints/ssl-cert-monitor-mvp and always will be. The $24 buys the packaged 1-click installer; building from source is free.
In a SQLite database on your own server. The checker connects directly to your hosts, so run it from a box that can reach them, and nothing goes to any third-party API.
