Boring monitoring,
run on a cron,
not a vibe.
SSL, domains, DNS, uptime, headers, SEO, deliverability — every probe an agency sells, run on every client domain, every morning. One inbox, one dashboard, one PDF the client actually reads.

Find out from us, not your client.
Without Pleenx
- Client calls Monday morning — site has been down since Friday
- TLS expired silently overnight; their checkout returns a browser warning
- DNS quietly flipped during a migration; mail bounces for a week
- You pull a one-shot screenshot for the monthly invoice; client doesn't care
With Pleenx
- Slack ping at 08:01 UTC — TLS expires in 14 days, here's the cert
- Daily probe catches the DNS drift the same morning it happens
- Branded PDF report ships to the client on the 1st, your logo, our data
- Client renews on inertia; you charge $79/mo, we charge $0.79/domain
Three steps. Thirty seconds. No agents.

Paste hostnames
Add client domains one at a time, paste a CSV, or import from a spreadsheet. We figure out the rest.
status.client.com - /02
We probe externally
No agents on client servers. We hit each domain from outside, exactly like a visitor would.

Alerts go where you live
Email, Slack, Discord, Telegram, signed webhooks. The first probe runs in 30 seconds.
→ #monitoring
Twelve probes. One pipeline. Every alert routed.
TLS handshake
Chain validation, hostname match, expiry windows. 30 / 14 / 7-day alerts before the cert dies.
Uptime + latency
Real fetch from outside. Status code, redirect chain, final URL, response time. Not a ping.
Core Web Vitals
LCP / INP / CLS via PageSpeed Insights. Trend over 30 days, not a one-shot Lighthouse run.
WHOIS / RDAP. Catches the card-on-file decline a week before the site dies.
Drift detection on every record. JR-dev-friendly diff format.
Catches the deploy that ships noindex to prod. Yes, it happens.
Policy parsing, not just present/absent. The audit your client's bank asks for.
Mozilla-style scoring with deltas over time.
SHA-256 of normalised body. Notices when the homepage suddenly says "hacked by zer0".
Asserts page contains expected text. Catches broken pricing pages.
Ship status to status.youragency.com. DNS challenge auto-verified.
GET /v1/domains, POST /alerts. Plug into your own stack.

Pleenx vs UptimeRobot
Free tier is unbeatable for solo uptime. But monitoring is more than 'is it up?' for agencies.
Pleenx vs Better Stack
Beautiful product for SaaS teams. We're the white-label-first alternative for client portfolios.
Pleenx vs PerkyDash
Same agency niche, different angle: they sell 'become a reseller,' we sell 'catch failures first.'
Built for the platforms agencies actually live on.
Pleenx for WordPress agencies
External probes that catch what ManageWP can't see — SSL handshake, WHOIS expiry, DNS drift, email auth.
Pleenx for Shopify agencies
Shopify hosts the store. We watch the custom domain, the checkout funnel, the sending domain, the SEO.
Pleenx for Webflow agencies
Webflow runs the site. We run daily checks on every failure mode Webflow doesn't surface.

“We built Pleenx because every agency we know was reactive. Their client called first, then the agency scrambled. Pleenx flips that — the alert is in your inbox before the client even refreshes the page.”
