The company behind Klaxel.
Crescera Systems builds and operates Klaxel — automated domain, DNS, deliverability, and web-security monitoring for the MSPs and agencies who manage domains for their clients.
“To make sure no domain an MSP or agency is responsible for ever breaks silently — and to run the product that guarantees it like we mean it.”
Why Klaxel exists
Agencies and MSPs manage domains their clients never think about — until a certificate expires, DMARC breaks deliverability, or a domain lapses and a site goes dark. Registrars email the client, who ignores it. By the time anyone notices, the agency looks responsible.
We built Klaxel to close that gap: monitor every client domain automatically, grade its health from A to F across fourteen checks, and raise the alarm the moment something slips — so the team responsible hears about it first. That single, well-defined job is the whole product.
A modern, AI-assisted toolchain lets us ship quickly and safely — every change goes through automated testing and a security scan before it reaches you.
What we believe
Focus over features
We'd rather solve one problem completely than ten partially. Klaxel does domain monitoring — thoroughly — and nothing it doesn't need to.
Reliability first
Klaxel runs in the background and has to earn trust. Every change ships with automated tests and a security review before it merges.
Honest and simple
Clear pricing, no dark patterns, and software you can adopt without a consultant. If it isn't a fit, we'll say so.
Built to last
We operate Klaxel for the long haul — maintained and improved, not shipped once and forgotten.
