01
Daily checks of every client site
Each hostname is inspected every day for TLS certificate expiry and domain registration expiry, so a missed calendar reminder is not your last line of defense.
For web agencies, MSPs, and freelancers
Never let a client's SSL certificate or domain expire again
Daily SSL certificate and domain expiry monitoring for web agencies, managed service providers, and freelancers. Check a site for free, then join the founding-member waitlist to watch every client domain from one place.
Built for shops that hold a lot of client keys — without ever holding the keys.
One missed renewal can take a client site offline. ClientLapse watches the dates that actually matter and tells you early enough to act.
02
Email and Slack alerts before expiry
Get a warning while there is still time to renew — not after the browser warning appears. Alerts are plain, specific, and named by client.
03
Sites grouped by client
Keep a clean inventory: each site sits under the client it belongs to, so a freelancer and a fifty-person agency can both find what they need.
04
Branded monthly client report
Send a short, professional report that shows every certificate and domain you watch for that client. Useful proof of the work you already do.
05
Bulk import
Paste a list of hostnames or upload a CSV. The setup should take minutes, even if you already manage dozens of sites.
06
Public data only
We read the public TLS certificate and public RDAP registration records. We never ask for, store, or handle private keys, DNS secrets, or registrar logins.
How it works
A short path from the free checker to a watched client list.
Check a site
Enter one hostname. You'll see the issuer, dates, days left, subject alternative names, whether the chain is trusted, and the domain's registration expiry when RDAP is available.
Join the waitlist
Founding members lock in the agency plan price. Tell us roughly how many sites you manage so we can size the first release honestly.
Watch the portfolio
When the full product opens, import your client list, group sites, and get alerts plus a branded monthly report — without changing how you renew certificates.
Founding member pricing
A simple agency plan. Annual billing is the better value and helps us keep the monitoring reliable.

Founding Agency
For agencies, MSPs, and freelancers watching client sites.
$19
/ month
or $190 / year — two months free. We recommend annual.
- Up to 50 hostnames
- Daily certificate and domain expiry checks
- Email and Slack alerts
- Sites grouped by client
- Branded monthly client report
- Bulk import
This is the planned founding price for the first agencies to join. It is not a paid subscription until you approve a charge. The free checker stays free.
Why agencies stay
A missed expiry hurts more than the monthly fee. Client lists tend to grow, not shrink, and the product is quiet on the days everything is fine.
Need more than 50 sites? Join the waitlist and tell us how many you manage. We'll follow up with a sensible next tier rather than forcing a surprise overage.
Questions
Do you need private keys, DNS secrets, or registrar logins?
No. ClientLapse only reads public information: the TLS certificate a server already presents to any visitor, and public domain registration data from RDAP. We never ask for or store private keys, CSRs, API tokens, or registrar passwords.
What does the free checker actually look at?
For one hostname it opens a TLS connection on port 443, reads the peer certificate (issuer, validity window, days left, subject alternative names, and whether the chain is trusted), and looks up registration expiry through RDAP using the IANA bootstrap directory. Some TLDs do not publish RDAP; in that case the certificate result still appears and registration expiry is marked unavailable.
Will you scan internal or private hosts?
No. The checker accepts public hostnames only. IP addresses, localhost, and names that resolve to private, loopback, or link-local addresses are rejected.
When does the paid product start?
The agency plan is opening to founding members after this waitlist. You'll get an email before any charge, and nothing is billed without your approval. The planned founding price is $19/month or $190/year for 50 sites.
What if a check or alert is missed?
Reliability comes first. A missed alert is the main risk this product exists to prevent. The free checker is a preview; the paid monitor is being built around daily checks, clear failure visibility, and simple alerts — not around a long feature list.
