Observability platforms charge per host. Self-hosted alternatives keep costs predictable as you scale.

Application monitoring and observability platform

Why consider the swap

If you currently rely on DataDog and want more control over data, lower long-term costs, or a open-source licensing model, VictoriaMetrics covers most of the same ground.

What you trade off

Most open-source alternatives require more setup than their commercial counterparts and may lag on polish, mobile apps, or ecosystem integrations. Check the project’s documentation for current feature parity with DataDog before committing.
