You’re right to be cautious. The Marketplace module is quite old, so it may not be a good fit for production in Mendix 10.
As an alternative, you could consider integrating Sentry manually via the Java SDK:
This approach is usually more stable and avoids relying on outdated modules.
One thing to keep in mind: Sentry works mainly for backend errors in Mendix. Capturing frontend (nanoflow/PWA) errors may require additional JavaScript setup.
You could also consider Mendix built-in monitoring or tools like New Relic / Dynatrace as alternatives.
If this helps, please mark it as the accepted answer.
