Webflow runs the site. We run the boring checks.
Webflow's hosting and SSL provisioning are excellent. They're not enough on their own to bill a client for monthly monitoring. Pleenx covers the gap — daily probes on every failure mode Webflow doesn't surface in its dashboard.

WordPress agencies have ManageWP. Shopify agencies have a dozen monitoring options. Webflow agencies have nothing built specifically for them — until now. Pleenx is the external-probe layer that gives Webflow agencies the same monitoring story Webflow itself doesn't try to provide: DNS drift, SSL renewal validity, plan-limit visibility, form delivery confirmation, SEO health, email auth.
What actually breaks on Webflow sites.
Custom domain SSL silently broke
Webflow auto-provisions Let's Encrypt, but renewal can fail if DNS records change or the client's DNS provider rate-limits ACME challenges. UI may say 'enabled' while the live cert is expired.
Webflow plan limits hit without warning
Site hits its CMS items, form submissions, or bandwidth cap. New content can't publish. Daily API poll catches it before the client tries to add content and gets blocked.
Contact form silently stopped delivering
Zapier integration deauthenticated. Form submissions land in Webflow's submission list but nobody gets notified. Synthetic form-submit test confirms end-to-end delivery weekly.
DNS dropped Webflow's required records
Client migrated DNS provider; the A on apex and CNAME on www didn't transfer. Site goes dark. Daily DNS probe catches the change pre-migration completion.
Third-party embed broke
Calendly widget URL rotated. The embed silently 404s on the contact page. External probe fetches the page and notices the broken resource.
Page launched with noindex set
CMS template had robots meta set to noindex, never noticed. Page invisible to Google for months. Daily SEO probe surfaces it within 24h of going live.
What we run daily, in priority order for Webflow.
- /01/sslTLS handshake validation on custom domain
Webflow's UI lies about cert state more often than you'd think
- /02/whoisDomain WHOIS / RDAP expiry
Webflow doesn't register the domain — that's at the client's registrar
- /03/dnsDNS A on apex, CNAME on www, TXT records
Webflow requires exact records; drift breaks everything
- /04/httpHTTP uptime + page load + embed health
Catches broken third-party scripts and 4xx on linked resources
- /05/syntheticContact form / lead form synthetic
Highest-impact monitor for a Webflow lead-gen site
- /06/seoMeta · canonical · robots · sitemap.xml
Catches noindex shipped to prod by mistake
- /07/email-authSPF · DKIM · DMARC for sending domain
Webflow doesn't manage email — that's still on the client's domain
