X-Ray suits teams tracing application requests across AWS services and other dependencies. It may also fit teams using OpenTelemetry, though AWS recommends migrating to OpenTelemetry as SDK and daemon releases are limited to security fixes beginning February 25, 2026.
SigNoz suits teams that need to observe application and infrastructure telemetry across logs, metrics, and traces. The self-hosted option may fit teams prepared to manage the supporting infrastructure themselves.
