A good APM tool I’ve been using for a few years is Apache Skywalking: https://skywalking.apache.org/
It might not do everything Sentry does but it definitely has helped with tracking down some issues, even production ones and runs in a fairly manageable setup (in comparison to how long even the Sentry self-hosted Docker Compose file is).
What’s more, if you want, you can even use regular PostgreSQL as the backing data store (might not be quite as efficient as ElasticSearch for a metrics use case, but also doesn’t eat your RAM like crazy).
