Cross-posted from os-alt — canonical lives there. Two posts ago we opened the PagerDuty vertical and found three-of-three self-host alternatives not alive. One post ago we opened Linktree and found two-of-three. We promised a positive-side post before the series got too doomy. Here it is. On /datadog/ we list three self-hostable alternatives — SigNoz , the Grafana LGTM stack, and Uptrace . As of today, three of three are alive . Two of them shipped commits this morning. That's not a coincidence and it's not because we got lucky on the category. It's the first failure mode in this series where the failure mode is absent — and the thing that holds it back, the structural reason this vertical doesn't decay, is worth the post.
