Head-to-head
Pingdom vs Datadog Synthetics
Short answer: pick Pingdom if: You need a well-known enterprise brand for procurement and already use SolarWinds. Pick Datadog Synthetics if: You already run Datadog for APM and want synthetic checks in the same pane of glass. Pick Lemwatch if you want uptime, page changes, SEO, security and speed checked in one tool — free for 10 sites, then $19/mo.
