Renewly: Cert & Domain Watch

An expired TLS certificate breaks trust in your site in an instant. A lapsed domain can lose it entirely. Renewly watches both, on your device, and warns you long before either one runs out. Certificate lifetimes are getting shorter every year. Under the CA/Browser Forum schedule, the maximum TLS certificate validity drops to 200 days in 2026, 100 days in 2027, and just 47 days in 2029. Renewals are becoming too frequent to track in your head. Renewly does the watching for you. WHAT RENEWLY MONITORS Certificate expiry A direct, on-device TLS handshake reads each host's certificate: issuer, expiry date, chain validity, hostname match, TLS version and serial. It reports the expiry even when a certificate is already expired or invalid. Domain registration expiry Renewly looks up your domain's registration expiry through public RDAP and WHOIS registries, so you are warned before a domain itself lapses, not just its certificate. ALERTS THAT REACH YOU IN TIME Renewly schedules local notifications 14, 10, 5, 1 days and 6 hours before each expiry. There is no push server in between, so alerts fire on time even if you never open the app. A background refresh and a re-check on launch keep renewals and changes up to date.

WHO IT IS FOR Solo operators, indie developers, freelancers and small teams who run a handful of sites and cannot afford to discover an outage after it has already happened. Renewly is an auxiliary reminder and should not be your only safeguard. Certificate and domain data depends on registry responses, the network and OS background execution.
