Does Klaxel replace Hudu?

No. Hudu is your IT documentation system of record — knowledge base, passwords and assets — and it's very good at that. Klaxel is a domain-health scorecard that grades each client domain A–F and alerts you when something breaks. On Core MSP ($249/mo) and up, Klaxel can sync domain health back into Hudu; it doesn't replace it.

Doesn't Hudu already monitor domains with Radar?

Hudu Radar, a paid add-on at about $9 per company per month, added SPF/DKIM/DMARC tracking in v2.37.0 — but it tracks the raw records and their change history, not a graded posture. It doesn't check blacklist/DNSBL reputation or DNSSEC health. Klaxel grades all of that A–F across 14 daily checks.

Can I run Klaxel alongside Hudu?

Yes — that's the point. Keep documenting in Hudu; let Klaxel watch email auth, blacklists, TLS, DNS, DNSSEC and expiry across every client domain and alert you the moment one slips.

Can Klaxel open a ticket in my PSA?

Yes — on Core MSP ($249/mo) and up, a domain-health event can auto-open a native ConnectWise ticket, or fire a webhook to any PSA that accepts one (HaloPSA, SuperOps, and more). Autotask is coming. That's the workflow win over a documentation tool: the domain problem lands in the queue your techs already work — not just another email.

Grade any client domain free at klaxel.com/check — no signup required. Full monitoring starts at $99/mo with a 14-day free trial.

Klaxel monitors every domain you own or manage across 14 automated infrastructure checks — TLS, email authentication (SPF/DKIM/DMARC/MX), web security, DNS, DNSSEC and blacklist reputation — distills them into one A–F grade per domain, runs a daily domain-expiry guardian on top, re-checks daily, and emails you the moment anything slips. Built for MSPs and agencies monitoring client domains at scale.

What does Klaxel check?

The A–F grade is built from 14 automated infrastructure checks across 6 categories: Certificates & TLS (cert expiry plus a deep SSL/TLS posture grade), Email auth (SPF, DKIM, DMARC, MX), Web security (HTTPS enforcement, HSTS, redirect integrity, subdomain-takeover detection), Indexability (robots/sitemap presence plus noindex-leak detection), DNS (nameservers, DNSSEC), and Reputation (IP/domain blacklist / DNSBL). On top of the grade it runs a daily domain-expiry guardian and brand-watch / typosquat monitoring.

Which TLDs are supported?

Any TLD with an official RDAP server in the IANA bootstrap registry — including .com, .net, .org, and .app. For ccTLDs not in the RDAP bootstrap (.io, .co, .me) we fall back to commercial WHOIS, so those are supported too (best-effort). The full A–F health grade runs on any well-formed domain regardless of expiry-source.

How do the alerts work?

You get an email the moment a security, deliverability or availability signal regresses (TLS, DMARC/SPF/DKIM, MX and more), a grade-drop email when a domain's overall letter grade slips, and an escalating expiry countdown at 60, 30, 14, 7, and 1 day out. Alerts are best-effort reminders; you remain responsible for renewing your domains.

What does it cost and can I get a refund?

Klaxel has three monthly plans — Starter $99 (100 domains), Core MSP $249 (500 domains), and Enterprise $499 (2,000 domains) — with annual billing at 2 months free. Need more than 2,000 domains? Contact us. Every plan starts with a 14-day free trial, cancels anytime, and has a 30-day money-back guarantee. Email support@klaxel.com within 30 days of your first charge for a full refund.

Klaxel vs Hudu, side by side

Capability	Hudu	Klaxel
IT documentation, passwords & assets	Core product — modern IT documentation: knowledge base, password and asset management.	Not our job — Klaxel monitors your domains and, on Core MSP ($249/mo) and up, syncs their health back into Hudu; it doesn't replace your docs.
Domain expiry	Tracked via the Hudu Radar add-on (about $9 per company per month).	Daily RDAP expiry check on every plan.
SPF / DKIM / DMARC posture, graded A–F	Records only — Hudu Radar (v2.37.0) tracks the SPF/DKIM/DMARC records and their change history, but shows the records, not a graded posture.	Graded A–F.
Blacklist / DNSBL reputation	No blacklist / DNSBL check documented.	Daily blacklist / DNSBL reputation check.
SSL, DNS & DNSSEC health, graded	Record tracking with change history; no DNSSEC health check, and not graded.	SSL/TLS, DNS and DNSSEC checked daily and graded A–F.
Alert the moment it breaks	Lookup on demand.	Break/recover alerts the instant a check regresses, plus a grade-drop alert.
Auto-cut a PSA ticket from a domain-health event	No PSA ticket from a domain-health event.	A native ConnectWise ticket — or a webhook to any PSA that accepts one (HaloPSA, SuperOps, and more) — on Core MSP ($249/mo) and up. Autotask coming.
White-label monthly client report	No white-label domain-health report.	White-label monthly client PDF on Core MSP ($249/mo) and up.

What Hudu does well

Hudu is a genuinely good modern IT documentation platform — a knowledge base, password management and asset tracking that MSP techs actually like using. That's its core product, and Klaxel doesn't try to replace it. If you run Hudu, keep running Hudu. Klaxel's job is narrower and different: grade the health of every client domain and tell you the moment it breaks.

Runs alongside your stack

Klaxel sits next to Hudu, not on top of it. Your team keeps documenting in Hudu; Klaxel runs 14 graded checks a day on every client domain — email authentication (SPF, DKIM and DMARC), blacklist/DNSBL reputation, SSL/TLS, DNS and DNSSEC — and rolls them into a single A–F grade, plus a daily RDAP domain-expiry guardian on top. When a grade drops or a check breaks, Klaxel alerts you — and on Core MSP ($249/mo) and up it can open a native ConnectWise PSA ticket, or fire a webhook to any PSA that accepts one (HaloPSA, SuperOps, and more), automatically.
