OpenObserve vs ClickHouse
Purpose-built observability, not a DIY database project. Logs, metrics, traces, dashboards, and alerts out of the box—no schemas to design, no UI to bolt on.
TRUSTED BY INNOVATIVE TEAMS

Why teams switch from ClickHouse
ClickHouse is a great OLAP database—but observability on it is a project you have to build and run yourself
No DIY Stack to Build
ClickHouse gives you tables. OpenObserve ships log search, dashboards, alerts, and traces out of the box—no Grafana or HyperDX glue.
No Schema Engineering
No partition keys, ordering keys, or materialized views to design and re-tune. Send data and query it—schema is handled for you.
Predictable Ingest Pricing
No compute unit-hours, per-TB storage, egress, and managed-ingestion line items to forecast. One simple ingest-based price.
Logs, Metrics, Traces Unified
One platform with built-in correlation—no separate tables, Grafana panels, and Jaeger to stitch together during an incident.
OpenTelemetry-Native
Native OTLP endpoints for logs, metrics, and traces. Repoint your existing OTel Collector—no exporter plugins or insert tuning.
Minimal Operational Overhead
No shards, replicas, or Keeper quorums to babysit. Stateless nodes on object storage—scale up and down without rebalancing.

Migrating from ClickHouse
If you already collect telemetry with OpenTelemetry, migration is mostly a collector reconfiguration.
Repoint your OpenTelemetry Collector
Deploy OpenObserve alongside ClickHouse and add its OTLP endpoint as a second exporter in your OTel Collector config. Dual-ship logs, metrics, and traces—no application code changes, no ClickHouse exporter tuning.
Recreate dashboards and migrate alerts
Translate your ClickHouse SQL queries to OpenObserve's SQL—most carry over with minimal changes. Rebuild key Grafana or HyperDX dashboards in OpenObserve's built-in UI and configure alerts natively, no external alerting stack.
Complete cutover and retire the DIY stack
Gradually shift workloads to OpenObserve, validate results, then decommission the ClickHouse tables, materialized views, and dashboard glue you were maintaining. Our team can help accelerate this process.
"OpenObserve is super fast, definitely very lightweight, and you can get started with an initial POC in two to three minutes to be honest."
Frequently Asked Questions
Common questions about switching from ClickHouse to OpenObserve
Yes—if your goal is observability rather than general-purpose analytics. ClickHouse is an excellent OLAP database, but using it for logs and traces means building and operating your own stack: schema design, ingestion pipelines, a UI (Grafana or HyperDX), and alerting. OpenObserve is a purpose-built observability platform with logs, metrics, traces, dashboards, alerts, and pipelines included. If you need a general analytics database for product or business data, ClickHouse remains a great choice—many teams use both.
ClickHouse Cloud is usage-based: compute billed per unit-hour, storage per compressed TB per month, plus separate data transfer charges and per-GB fees for managed ingestion (ClickPipes). Costs vary with query load and are hard to forecast, and they don't include the engineering time spent maintaining the observability layer on top. OpenObserve uses simple ingest-based pricing, and self-hosted OpenObserve is free—storage on S3 or other object storage keeps long retention cheap.
Usually less than you'd expect, because most ClickHouse observability stacks already use the OpenTelemetry Collector. Migration is largely a collector reconfiguration: add OpenObserve's OTLP endpoint as an exporter, dual-ship for a few weeks, rebuild key dashboards and alerts, then cut over. Historical data can stay queryable in ClickHouse until its retention expires—most teams don't backfill. Simple setups migrate in days to weeks; heavily customized stacks take longer.
Yes. OpenObserve is SQL-native for querying logs and traces, so your team's SQL skills carry over directly—most queries translate with minor dialect changes. You also get PromQL for metrics and VRL-based functions for data transformation, without needing to design tables, partition keys, or materialized views first.
Yes. OpenObserve is open source and can be self-hosted as a single binary for small setups or as a highly available cluster on Kubernetes via Helm. Data is stored in open Apache Parquet format on object storage (S3, GCS, Azure Blob, MinIO), so there's no lock-in—your data stays readable by any Parquet-compatible tool.
ClickStack (ClickHouse + OpenTelemetry + HyperDX) narrows the gap, but it's still a stack of components you assemble, configure, and operate—database, collector, and UI each with their own scaling and upgrade story. OpenObserve delivers the same outcome as a single integrated platform: one deployment, one UI, built-in alerting and pipelines, and stateless nodes on object storage. Fewer moving parts means less engineering time spent on the tooling itself.
ClickHouse is one of the fastest OLAP databases available, and for arbitrary analytical queries over huge datasets it's hard to beat. OpenObserve is optimized specifically for observability workloads—time-range scans, full-text log search, trace lookups, and dashboard aggregations—using columnar Parquet with partitioning and caching. For typical observability queries, performance is fast where it matters, without the schema tuning ClickHouse needs to get there.
Yes. OpenObserve is SOC2 Type II certified and ISO 27001 compliant. We process over 2 PB of data daily across thousands of deployments, including Fortune 100 enterprises. Enterprise features include RBAC, SSO, sensitive data redaction, and dedicated support.
OpenObserve: the purpose-built ClickHouse alternative for observability
An open-source, SQL and OpenTelemetry-native observability platform—logs, metrics, traces, dashboards, and alerts out of the box, with no schemas, pipelines, or UI glue to build. Radius.ai got started with a working POC in minutes, not months. Also evaluating other tools? See how OpenObserve compares to SigNoz, Elasticsearch, Grafana.
