Monitoring for Web Agencies

Monitoring a portfolio of client sites is a different job than monitoring one product. Each client has different infrastructure, different failure modes, and a different threshold for how long they'll wait before calling you. WatchCron handles the external checks that catch problems before clients notice them: uptime, SSL, domains, ports, cron jobs, and blocklists, with alerts and reports scoped per client.

Monitoring for an agency pays for itself on the day nothing breaks

That sounds backwards, but it's true. Clients don't call to say “thanks for keeping the site up.” They call when it's down. The value of monitoring for an agency isn't the incident you caught. It's that you responded before the client noticed, every time, until they stop worrying. That's what they're actually paying for in a retainer, but it's impossible to demonstrate without numbers.

WatchCron gives you those numbers. 99.97% uptime, two incidents caught and resolved four minutes before they affected users, average response time steady at 340ms. One line in a monthly uptime report that justifies a retainer more concretely than any task list.

Someone else's business, your responsibility

Monitoring your own product is one thing. Monitoring 15 client sites, each with its own stack, its own hosting, and its own expectations for how fast you should respond, is a different problem entirely. One client runs WordPress with WooCommerce and a wp-cron that quietly died after a hosting update. Another has a React SPA with a separate API server and an SSL certificate that Let's Encrypt failed to renew. A third sends transactional email through an IP that landed on a spam blocklist.

None of these failures look alike. But each one ends the same way: a call asking “Why did I find out before you did?” External monitoring — uptime, SSL, domains, ports, cron jobs, blocklists — covers these blind spots before the client discovers them.

One notification to the wrong person at 2 AM, and the whole team starts muting the channel

Monitoring that works for one project falls apart at fifteen. Every alert in one Slack channel is the first step toward a team that stops responding. Client A's staging site fires overnight, the developer responsible for Client B mutes the channel, and two weeks later Client B's production site goes down with the alert buried in noise.

In WatchCron, each client lives in a separate project. Checks, notification channels, and team members are all scoped per project. The person managing a WooCommerce store gets alerts for that store. When something breaks, the notification reaches the person who can actually fix it, not everyone at once.

SSL certificates don't break when they expire — they break when auto-renewal quietly stops working

Agencies used to renew certificates manually once a year, and the process was painful enough that people tracked it. Let's Encrypt removed the pain and the visibility along with it. A DNS change, a server migration, a broken webroot validation path. The renewal fails silently, nobody checks, and two months later the browser starts showing warnings.

With 20 client sites, that's statistics, not bad luck. SSL monitoring checks each certificate and alerts before expiry. Auto-renewal worked? Silence. It didn't? You have time to fix it before the client sees the crossed-out padlock.

“Is it fixed yet?” is the worst question a client can ask

When something goes down, a client can't sit in your Slack workspace waiting for updates. They need a page they can open themselves and see: status “investigating,” timestamp of the last update, incident history. Something they can forward to their own management.

WatchCron's status pages work per project. Create an incident, post updates as your team works through it, and the page reflects the current state. When the incident closes, the timeline stays. The chaotic “is it fixed yet?” thread becomes a professional response that strengthens the client relationship.

What this costs with 15 clients

A typical client site needs 3-4 monitors: uptime, SSL, domain, maybe a cron job. Fifteen clients is about 50-60 checks. The free plan covers 20 (enough for 5-6 clients). Starter gives you 75 checks at $7/month with Slack and Telegram alerts. Pro covers 250 checks and 10 team members — enough for a portfolio of 40-50 sites.

Port and domain monitors are unlimited on every plan. Pricing is flat — no per-domain surcharges or per-site licenses.
