Switching between logging tools is generally possible but involves migration effort: exporting your data or configuration from Grafana Loki, re-importing or reconfiguring in Papertrail, 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 Papertrail on a non-production project first before migrating.
Grafana Loki (78/100) is the better fit for teams who prioritise price / value — its strongest dimension — and who want a free entry point.
