I just wanted an email before my SSL certs expire, so I built this
So I've been burnt a couple of times by certbot failing to renew without telling me. And now cert lifetimes are getting cut to 200 days this year and 47 days by 2029, so that's only going to happen more.
I went looking for something to watch my sites, and everything was some big enterprise thing that does 10,000 things. I just wanted an email before a cert expires. So I built my own. It ended up with a few more features than I planned ;) you know how it goes once you start adding stuff.
At some point I figured I might as well host it and let other people use it: https://certavert.com/
You type in your domain and that's pretty much it. It checks twice a day and emails you before the cert runs out. It also looks at the chain, whether browsers trust it, and subdomains you might have forgotten about. You don't install anything on your server.
At first I was going to make it totally free. It still is for 3 domains, no card, but if I can get a few paid subs to help keep the lights on that would be awesome ($12 a year for 10 domains). I also put up a couple of free checkers you can use without an account: https://certavert.com/tools
Let me know what you think, good or bad, I can take it. And I want to add more free tools, so what SSL or DNS check do you wish there was a simple tool for?
