RadarKnow what expires next
Expiry tracking for people who look after other people's IT.
Every TLS certificate, domain and license across your clients in one list, sorted by due date. Radar checks every host daily and pings your team at 30, 14, 7, 3 and 1 days out.
Finds what you forgot
Type a domain, get every hostname with a live certificate from public CT logs.
No agents, no access
Only public data: the served certificate, CT logs and registry RDAP.
Alerts where you work
Email, Slack, Discord, Telegram or any webhook.
Certificates are getting shorter. A lot shorter.
The CA/Browser Forum is cutting public certificate lifetimes in steps until 2029, and Let's Encrypt stopped sending expiry emails in 2025. Anything renewed by hand, by a fixed cron job or by a vendor nobody remembers will start to fail.
The old maximum.
All public CAs. In force today.
Let's Encrypt default. Fixed 60-day renewal jobs break.
All public CAs.
Final step. About eight renewals a year per host.
Three kinds of expiry. One list.
Radar reads what is public and you type in the rest.
TLSCertificates
- Found automatically from Certificate Transparency logs
- Checked daily against what the server actually serves
- Broken chains and name mismatches flagged
- Mail, VPN and any custom port
REGDomains
- Expiry read from the registry over RDAP
- Registrar shown next to the date
- Catches the lapsed card on a forgotten registrar account
RENRenewals
- Microsoft 365 and Google Workspace seats
- Firewall and antivirus licenses
- Hardware warranties and support contracts
- Anything else with a date
Told in time. Every time.
One alert at each step, then a daily reminder in the final week until someone snoozes it. Snoozes follow the expiry date, so the next renewal is watched again automatically.
Flat price. No seats.

Good to know
- Do you need access to my servers or DNS?
- No. Radar reads the certificate a server presents, public Certificate Transparency logs and registry RDAP records. Licenses and warranties are dates you type in.
- Who is it for?
- Managed service providers, small IT teams and web agencies who look after many sites and renewals for many clients.
- Can it check mail servers or custom ports?
- Yes. Add any host:port that speaks TLS directly, for example mail.example.com:465 or vpn.example.com:8443.
- What is the 2027 readiness check?
- Radar looks at each host's renewal history. If it renews on a fixed ~60-day schedule it will break on 64-day Let's Encrypt certificates, and Radar flags it first.
- What if I cancel?
- You keep access until the end of the billing period, then drop to the free plan. Your first payment is refundable for 14 days.
- Who runs Radar?
- An independent software developer based in Indonesia. Payments are handled by our merchant of record. Questions go to hello@radardue.com.
