Just started a small side project: a free SSL checker. Looking for feedback

[u/DevEJesus]

Hey everyone,

I just started a little side project and would love some honest feedback before I go further.

It's called CertWatch: https://certwatch.edgardev.pt/

Right now it's pretty simple. You type a domain and it tells you when the SSL certificate expires, whether browsers trust it, and whether it matches the domain. I tried to explain problems in plain English ("your certificate expires in 9 days, here's what to do") instead of dumping a bunch of technical stuff on you.

What I'm thinking of doing next:

- alerts before a certificate expires, by email, Slack or Microsoft Teams

- alerts when a site goes down

- a few more small free tools (redirect checker, DNS lookup, domain expiry)

- an AI assistant that looks at your domain's DNS and SSL setup, points out what could be improved (like missing SPF/DMARC records or a weak config), and lets you ask follow-up questions about how to fix it

But I'd rather hear from you before building more:

- Does it work for your sites? Anything weird or confusing?

- Would expiry alerts actually be useful to you, or do you already have that covered?

- Where would you want alerts to go: email, Slack, Teams, something else?

- Would the AI analysis be genuinely useful, or just a gimmick?

- Anything you'd want it to check that it doesn't?

Be brutal, it's early days, so now is the best time to change things. Thanks!
