What's new in ClickStack - April 2026

In April's update for ClickStack, significant improvements were made to enhance the core experience of querying, alerting, and dashboards. The introduction of SQL-powered alerts allows users to seamlessly transition from writing queries and building dashboards to setting alerts without switching languages, enhancing the SQL-native observability workflow. Performance optimizations, including a redesigned logs schema and a major overhaul of autocomplete leveraging materialized-view rollups, offer faster and more responsive data handling. Heatmaps have been elevated to a first-class chart type, enabling easier visualization of data distributions within dashboards. Additional quality-of-life improvements include more flexible alert thresholds, enhanced alert history tracking, and user-friendly features such as scrollable pie chart legends and per-series number formatting. April's release also emphasizes community involvement through open source contributions and offers a preview of upcoming observability talks at the Open House event, showcasing how various teams utilize ClickStack with ClickHouse in production.
