Switching between logging tools is generally possible but involves migration effort: exporting your data or configuration from Logz.io, re-importing or reconfiguring in Datadog Logs, and updating any API integrations or environment variables in your codebase. The effort scales with how deeply embedded the tool is in your stack. Test Datadog Logs on a non-production project first before migrating.

Datadog Logs (78/100) is the better fit for teams who prioritise integrations and want a free entry point.
