ObsessionDB review
A capable free tier for developers who need managed ClickHouse without a fixed paid plan.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
ObsessionDB is a managed hosting service for ClickHouse workloads, using the official ClickHouse engine rather than a separate query system. It is aimed at developers and teams running real-time analytics and other ClickHouse workloads, with a free developer tier for initial projects and usage-based infrastructure for larger deployments. The service separates compute from storage, uses object-storage durability, and offers configurable compute sizes and node counts. Dedicated compute and private networking are also available for workloads with more specific infrastructure requirements.
The free developer tier includes up to 4 vCPU and 8 GB RAM, with no credit card required. Usage-based infrastructure prices compute by size and node count, while storage is charged by usage; ingress and egress are free, and there is no minimum commitment. Operational features include 24-hour point-in-time recovery, automated daily backups, distributed caching for frequently queried data, built-in monitoring, alerting, and notification channels. Autoscaling is forthcoming, so teams that require automatic capacity changes should assess whether configurable compute is sufficient for their workload.
ObsessionDB fits an existing ClickHouse ecosystem through the standard ClickHouse protocol, HTTP interface, clients, and drivers. Listed integrations include Grafana, Metabase, Superset, Tableau, DBeaver, Kafka, Spark, Airbyte, Debezium, Streamlit, and Looker. MCP connections extend the service to Claude Desktop, Cursor, and VS Code for AI coding-agent workflows. Developers should choose ObsessionDB when a free starting tier, managed operations, and broad tooling compatibility matter. Teams needing automatic scaling or longer backup retention without a custom plan may prefer an alternative.
