Teams hit Datadog or New Relic renewal sticker shock but have no migration playbook to move their existing instrumentation to a self-hosted stack without months of re-instrumenting

A 2024 HN thread about a $83,000 Datadog renewal cancellation sparked hundreds of comments from teams in the same situation. The ClickStack (open-source Datadog alternative by ClickHouse and HyperDX) launch in June 2025 got 241 HN points and 83 comments, with the top discussion being the painful migration process. The core issue: teams have years of Datadog dashboards, alert rules, and log parsing configs that do not export. Moving to Prometheus/Grafana/Loki requires re-building every dashboard and re-writing every log query from scratch. No tool automates the export of Datadog dashboard JSON, alert configs, and log parsing rules into equivalent Grafana/Loki/Prometheus formats. Teams that canceled Datadog are spending 1-3 months in migration limbo with broken observability.
