Know before your client does.
White-label website monitoring for agencies managing 10–100 client sites. Every stack in one dashboard, alerts before the phone rings, and client-branded status pages that prove your retainer's value — without a Sunday spent on screenshots.
Your monitoring stack shouldn't need its own project manager.
Most agencies watch client sites with a free uptime pinger, a WordPress maintenance dashboard, a certificate spreadsheet, and a monthly report assembled by hand. It works — right up until the gap between those tools is exactly where a client's site breaks.
- UptimeRobot pings the homepage — but misses the expired cert, the dead checkout link, and the cron job that stopped backing up.
- ManageWP covers the WordPress sites. The Shopify stores, custom apps, and client APIs? A second and third tool.
- The monthly client report means screenshots, spreadsheets, and a Sunday evening you never bill for.
- A client calls at 9:02 AM about their site being down. You didn’t know. That call costs more than any tool ever will.
- Free-tier tools now ban commercial use — running client monitoring on them puts your agency one ToS email from dark.
Why website monitoring for agencies is a different problem
Monitoring one product is easy. Monitoring a portfolio of client websites is a different job: every site has a different stack, a different hosting provider, a different point of contact, and a different tolerance for downtime. A single missed outage doesn't just cost uptime — it costs the trust that your retainer is built on. The agency that finds out about downtime from the client has already lost the argument about what the retainer is for.
That's why generic uptime checkers fall short for agency work. A homepage ping won't catch the SSL certificate expiring on a client's booking subdomain, the domain registration lapsing because the renewal email went to a departed employee, the nightly backup cron that's been silently failing for three weeks, or the broken link sitting on a checkout page. Relen runs all 13 check types against every client site — from 5 global regions, with multi-region confirmation so a single network blip never pages you at 3 AM.
And because agency monitoring is client-facing, presentation matters as much as detection: white-label status pages on client domains, per-client grouping, and uptime history you can put in front of a client without apology. Monitoring stops being an internal chore and becomes part of the service you sell.

Invite your whole team — free
Unlimited seats with role-based access on every plan. Your PM sees dashboards, your devs get alerts, your clients get status pages. Nobody gets an invoice per head.
Publish client-branded status pages
status.yourclient.com with their logo, on their domain, password-protected if internal. When something breaks, clients check the page instead of calling you.
Proof of value your clients can see — under your brand, not ours.
The hardest part of retainer work isn't doing the work — it's making the work visible. Relen turns invisible vigilance into artifacts your client sees with their own name on them.

Powered by your agency — no third-party branding
Monitoring isn't a cost. It's your highest-margin line item.
Agencies typically bill proactive monitoring inside a care plan at $20–50 per site per month. On the Business plan, your cost is about $2.45 per site. The margin funds the ten minutes a month you actually spend — and the peace of mind is what the client is really buying.
- Pay per site monitored — never per teammate
- One subscription covers uptime, SSL, DNS, domains, cron, links & performance
- Plans from 5 to 100 sites — upgrade as you win clients
- Price locked at signup. No legacy-plan surprises.

Agencies that stopped finding out from clients
“We manage 47 client sites across WordPress, Shopify, and two custom apps. Relen replaced three tools, and the per-client status pages alone justified the switch — clients stopped emailing us "is my site down?"”
“A client’s SSL cert would have expired on a Saturday. Relen warned us 14 days out. That one catch — one renewal email instead of a dead site — paid for the year.”
Agency monitoring — common questions
- Can I white-label status pages for my clients?
- Yes. Every Relen status page can live on a custom domain like status.yourclient.com, carries no Relen branding on paid plans, and supports password protection for internal pages. Your clients see a professional status page under their own name — not a third-party tool.
- Does Relen only work with WordPress sites?
- No. Relen monitors any website or service: WordPress, Shopify, Webflow, custom applications, REST APIs, TCP services, and cron jobs. If your portfolio mixes platforms — as most agency portfolios do — everything lives in one dashboard instead of one tool per stack.
- How do I organize monitors by client?
- Group every site by client name and add tags for hosting provider, plan tier, or SLA level. Filter the dashboard to a single client in one click, publish a per-client status page, and route that client’s alerts to a dedicated Slack channel or email.
- Do you charge per team seat?
- No. Every Relen plan includes unlimited team members with role-based access (owner, admin, member, viewer). You pay for the number of sites you monitor — never for the people who help you watch them.
- Can I bill monitoring on to my clients?
- Most agencies do. A typical care plan bills $20–50 per site per month for proactive monitoring and maintenance. On the Relen Business plan, 20 client sites cost $49/mo — roughly $2.45 per site — so monitoring becomes one of the highest-margin line items on your invoice.
- How fast will I know when a client site goes down?
- Checks run as often as every 30–60 seconds from 5 global regions. An alert only fires after failures are confirmed — consecutive-fail thresholds and multi-region verification prevent the false-positive noise agencies suffer with single-location tools.
- What check types are included for each client site?
- All 13 on every plan: HTTP uptime, SSL certificate expiry, domain registration expiry, DNS record changes, TCP ports, ping, cron/heartbeat, broken links, sitemap health, Lighthouse/Core Web Vitals, JSON app-health, mixed content, and DNS blocklist checks.
