Certwatch on Web Browser
Runs in any modern browser — nothing to install, works the same on any machine you log in from.
Setup on Web Browser
Get the code
Clone or download Certwatch from the repository (https://github.com/bensblueprints/ssl-cert-monitor-mvp) — the README documents the setup.
Deploy on your own server
Self-host on your own VPS or server — Docker or the one-command setup from the repo README. Point your domain at it when you're ready.
Keep your data yours
Your data stays on hardware you control — no third-party cloud, no per-seat pricing, no telemetry back to us.
Because Certwatch is self-hosted, "offline" is your call — run it on a LAN or behind a VPN and it never touches the public internet.
Certwatch on Web Browser — honest answers
Is it really free on GitHub?
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.
Where does my monitoring data live?
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.
