How to choose

If you're switching away from Sematext Synthetics, the most common reasons are budget (cheaper or free options below), features that don't fit your stack (uptime-specific tools beat generalists), or wanting self-hosted control. Pick 2–3 from the list above, run a 14-day side-by-side test, and switch only if the alternative is a clear win on at least one axis.
