It'll be hard to position this against Sentry. Sentry's a joy to use and their performance product is so helpful in debugging performance issues

We decided to self host sentry, which is an absolute beast to deploy, the open-source helm chart is nowhere near production level, and the underlying technologies are quite hard to maintain (Kafka, zookeeper, clickhouse...). We had to work on it constantly for two months to stabilize it, and now fear the moment we'll want to update. The dev teams love it, so it was worth the hassle!
