Tài liệu
Know your website.Know what to do next.
Uptime, certificates and security signals in one place. Clear explanations when something needs attention.
One website free. No card. Nothing to install.
Just need certificate expiry checks? Get the free GitHub Action.
OrionCmd reports what it can observe from the outside. It doesn't make changes to your site and can't promise a problem is solved — when the evidence isn't there, it says so plainly instead of guessing.
Free & open source
Free certificate expiry checker.
Know when a website's certificate needs renewing. Run the OrionCmd GitHub Action after each deployment, or add a daily check—even when nothing has changed.
No OrionCmd account or API key. GitHub runner allowances apply.
A renewal warning, not automatic renewal.
- Checks certificate trust, hostname, expiry, and the HTTP response.
- Fails at 21 days or fewer remaining. You can change the threshold.
- Daily scheduling and GitHub failure notifications are opt-in. Daily setup & notifications
For AI agents
Agents can run OrionCMD checks on any domain and pay per call, with no signup. A TLS, DNS, email-auth, security-header or expiry check costs 1 cent. The site-health bundle and the new A to F domain grade cost 3 cents each, paid in USDC over x402.
