Plain-English website monitoring
Best product for this task
DomainDash
dev-tools
DomainDash watches the client websites you maintain, covering uptime, SSL, DNS, and domain registration, and tells you when something breaks in plain English (Healthy / Slow / Down) before the client notices. Built for freelancers and small agencies tired of finding out about expired SSL certs from the people who pay them. Free tier covers 1 site, paid plans scale by site count rather than per-seat. Free public check tool at domaindash.io/check works without signup.

What to expect from an ideal product
- DomainDash automatically checks your SSL certificates every day and sends you alerts weeks before they expire, so you never get caught off guard again
- Get plain English notifications that say "SSL expires in 14 days" instead of confusing technical error messages that waste your time
- Monitor all your client websites from one dashboard rather than manually checking each certificate or setting up complicated scripts
- Receive alerts before your clients notice problems, protecting your reputation and avoiding those awkward phone calls about broken sites
- Start tracking SSL expiration for free with one website, then add more sites as your business grows without paying per user
