Who's behind Radardue

Radardue is built and run by me, Syahid, a solo developer in Indonesia. No investors, no sales team, just one person who reads every email.

Why it exists

Expired certificates and lapsed domains are some of the most avoidable outages there are, and they're getting easier to miss. Public certificates drop to 100 days in March 2027 and 47 days by 2029, Let's Encrypt moves to 64 days in February 2027, and the people who feel it most look after dozens of clients at once. I wanted one list with every client's certificates, domains and renewals, and alerts that reach the whole team before anything lapses.

I use it myself

I also run Nyebar, an event ticketing platform for communities. Radardue watches Nyebar's certificates, its domain and its servers every day, and its alerts land in the Nyebar team's Telegram.

How it's run

• Hosted on a server in Singapore, with encrypted off-site backups every night.
• Payments are handled by Creem, our merchant of record; Radardue never sees your card.
• No tracking cookies and no ad pixels. See the privacy policy.
• Your data is yours: export everything to CSV or subscribe to your renewals in any calendar via iCal, anytime. No lock-in.
• Free for 25 items, with a 14-day refund on any paid plan. See refunds.
