Lapsewatch keeps your client domains in one list with the days left for each, soonest first. Spot the certificate that lapses next before the client calls.
The free checker needs no account. Your domain list stays in your browser.

Nobody noticed until the client called.
Auto-renewal on small-business shared hosting can fail without a sound.
It is easy to forget.
Calendar reminders go stale as you add and drop client sites.
Paste lines like 'example.com, 2026-12-01' into the free checker and get a table sorted by days left.
Read each row at a glance: Expired, Urgent (7 days or less), Soon (30 days or less) or OK.
Add, edit and remove them. Free for up to 5 domains.
Paid plans: keep up to 100 domains in your list.
Paid plans: download a calendar file with reminders at 30, 14 and 7 days before each expiry.
Paid plans: copy ready-made Slack and email reminder text, and import or export your list as CSV.
Simple, no surprises.

The multi-domain expiry checker is free. Paste your lines and get a sorted days-left table. You can also save a list of up to 5 domains. No account is needed for the checker.
A list of up to 100 domains, a calendar file (.ics) with reminders at 30, 14 and 7 days, copy-ready Slack and email reminder text, and CSV import and export.
No. A web page cannot read a site's certificate, so you enter each expiry date yourself. You can find it in your browser's certificate viewer or with the openssl command. The checker accepts dates like 2026-12-01 and openssl 'notAfter' lines.
No to both. Lapsewatch does not send email or Slack messages on its own, and it never renews certificates. It shows what is close to expiring, gives you a calendar file, and writes reminder text you can paste into Slack or email.
Your domain list is saved in your own browser (local storage). The checker stores nothing. Lapsewatch makes no network calls with your domains.
All paid plans unlock the same Pro features. Agency Annual is the Agency plan billed yearly at about 20% off, roughly two months free.
