Honest matrices covering features, pricing, and the specific checks each tool actually runs — so you can pick the one that fits how you work.
Each comparison page is generated from a fact registry with a verification date on every entry: entry-paid price, minimum check interval, free-tier status, and which checks the vendor actually ships. Where a vendor doesn't publish a figure we say so rather than guessing.
Price per monitored site at your actual portfolio size, not the headline plan price. Minimum check interval on the plan you'd really buy. Whether performance, SSL, DNS, SEO and content checks are included or sold separately. Alert quality — how quickly you're told, and whether the message explains the cause.
Lemwatch tends to win on breadth per pound for multi-site owners, and on alerts that explain themselves. It's the wrong pick if you need APM-grade tracing and log analytics, or on-call scheduling with escalation rotas — dedicated observability platforms do those properly.
