hyperdx
Resolve production issues, fast. An open source observability platform unifying session replays, logs, metrics, traces and errors powered by ClickHouse and OpenTelemetry.
Project mention: Show HN: ClickStack – open-source Datadog alternative by ClickHouse and HyperDX | news.ycombinator.com | 2025-06-05It would have even much better if the link was pointing to https://github.com/hyperdxio/hyperdx the actual source code.
Because right now without the message on HN here, I wouldn't know what "open source observability stack" meant when the webpage does not explain what HyperDX is, nor does it provide a link to it or its code. I was expecting the whole thing "Open Source Datadog" to be ClickStack Repo inside Clickhouse Github. Which is not found anywhere.
But other than that congrats!. I have long wondered why no one has built anything on top of Clickhouse for Datadog / New Relic competition.
The Clickhouse DB opened up the ocean of open source "Scalable" Web Analytics that wont previously available or possible. I am hoping we see this change again to observability platform as well.
