Reef vs UptimeRobot and Datadog: more than uptime, simpler than enterprise.
UptimeRobot is a popular tool for checking your website is up. Datadog is a large monitoring platform built for engineering teams. Reef sits in between: it watches far more than whether you're up, explains everything in plain English, and comes at one flat price.
What sets Reef apart
What you get with Reef
- Everything in one system. Your website, hosting, settings, storage and backups, logs and code, all watched by one tool, with one sign-in and one dashboard. No extra products to add on.
- Checks every 5 minutes, with deeper checks every hour. Your website from the outside every 5 minutes, your hosting every 15, and security and code every hour.
- The exact problem, the fix, and why. Reef reads the error logs and the code together, points to the cause with evidence, and tells you how to fix it, in plain English, not graphs.
- No alert overload. Problems are ranked high, medium or low, several problems go out as one alert, and each channel can be set to urgent only.
- The right person sees the right level. Everything for your IT person, urgent only for your CTO, just the monthly savings report for your finance director.
- Security and GDPR health checks. Exposed files, open admin pages, passwords in code, software with known holes, trackers without consent, a missing privacy policy, and data with no backups. Plus a map of where personal data sits across your database, code and logs.
- Finds money you're wasting. Idle servers, forgotten projects and paid services nobody uses, with what you'd save.
- Shows what it saved you. Every alert shows what catching it early saved, worked out from your own numbers, with a monthly total.
- A built-in safety net. Every change is logged, the owner is alerted if anyone switches Reef off or mutes an alert, and daily snapshots mean Reef's records can be restored for 14 days.
- Into your own tools, under your own brand. Alerts by email, Slack or signed webhooks into your developer's own tools, and IT partners can run Reef with their own name, logo and colours.
- Part of one platform. What Reef protected shows in your Exec dashboard next to the rest of your AI team, and IT partners run Reef for many clients, each with their own dashboard.
- Add more agents with a switch. Turn on more of our agents in your account, with no new system to set up: the Guest suite (Pearl, Marina and Wave), the Business suite (Rock: Pearl, Marina, Coral, Manta and Horizon), Reef for IT, or all of them. Same sign-in, same dashboards.
- Licence it or run it yourself. Pay monthly, or buy it once and run it in your own environment, with the source code, for full control (the IP stays with Lagoona).

Questions
Is UptimeRobot a good tool?
Yes. If all you need is to know the moment your website goes down, it does that well and has a free plan. Reef is for businesses that want to know what broke, why and how to fix it, and to have security, privacy, code and costs watched as well.
Is Datadog a good tool?
Yes. It's a powerful platform for engineering teams running large systems. Reef is for businesses that want the answers without needing an engineer to read the dashboards, at one flat price.
Can I run Reef alongside what I have?
Yes. Reef only needs read-only keys you control and can remove at any time, so you can run both side by side while you compare.
We're an IT provider. Can we resell Reef?
Yes, under your own brand. See partner pricing.
