ClickStack is an open-source observability stack for OpenTelemetry that brings logs, metrics, traces, session replays, and errors together. Its HyperDX interface provides Lucene-style search, SQL access, dashboards, alerts, event deltas, and event patterns. Collection includes native OpenTelemetry support and a bundled OpenTelemetry Collector. ClickStack uses ClickHouse storage and is designed to query high-cardinality telemetry; its site describes sub-second queries even on petabytes of data. It can also work with non-OTel wide event data when that data has a timestamp field. The software can be deployed self-hosted, in a hybrid setup, or in the cloud. Managed ClickStack runs on ClickHouse Cloud, which handles cluster operations, scaling, upgrades, backups, reliability, authentication, and user management. The managed offer advertises indefinite retention for high-cardinality telemetry and storage pricing below one cent per GB. The free open-source plan is available, alongside a managed trial with 30 days and $300 in ClickHouse Cloud credits; it ends when either the credits are used or 30 days pass.
Who it is for
ClickStack suits teams looking to collect and analyze OpenTelemetry data across logs, metrics, traces, replays, and errors. Its self-hosted, hybrid, cloud, and managed options give teams different deployment approaches.
What is good
- Brings logs, metrics, traces, replays, and errors together.
- Includes a bundled OpenTelemetry Collector.
- Offers SQL access, dashboards, alerts, and search.
- Can be deployed self-hosted, hybrid, or in the cloud.
What to know first
- Non-OTel wide event data needs a timestamp field.
- Managed trial ends after 30 days or when credits run out.
Verdict
ClickStack combines telemetry collection and analysis with several deployment choices. Teams should weigh its broad observability scope against the managed trial's credit and time limits.
