About
Built by a developer,
for developers.
Hey, I'm Sean — a software developer at Reedster LLC. I build full-stack web applications with a focus on clean, efficient code.
Xpiry started from a real problem: I was managing SSL certificates and domain renewals across multiple projects and kept getting surprised by expirations. The existing tools were either overpriced enterprise platforms or unreliable free checkers. I wanted something fast, simple, and built for developers who just need to know when things are about to expire.
When I'm not writing code, you'll find me skiing, rock climbing, or trail running.
What is Xpiry?
Xpiry monitors your SSL certificates and domain registrations around the clock. It checks expiry dates on a schedule, validates certificate chains, and sends you alerts before anything expires — via email, Slack, or webhooks.
The goal is simple: never let a certificate or domain expire again. Whether you're a solo developer with a handful of side projects or an agency managing dozens of client domains, Xpiry keeps everything in check.
Dog-fooding
I use Xpiry to monitor my own production services. If it's not good enough for my own domains, it's not good enough for yours.
