ObsessionDB

Managed ClickHouse hosting with an NVMe cache mesh that keeps p99 latency flat as data grows

0
freemiumPriced from a live cluster calculator rather than fixed tiers: you set compressed storage, compute per node (one compute unit is 2 vCPU / 8 GB, up to 256 GB per node before it becomes a custom quote) and node count. A worked example on the pricing page — 3 nodes at 64 GB with 10 TB compressed — comes to $3,840/mo compute plus $250/mo storage, or $4,090/mo total, which the calculator compares against $7,162/mo for other managed ClickHouse. Ingress and egress are always free, billed monthly in USD. A free developer tier (up to 4 vCPU / 8 GB) is available for evaluation, and a free performance audit comes with $3K in credits on conversion.View full pricing →

About ObsessionDB

ObsessionDB is managed ClickHouse hosting built around a single complaint: on most managed ClickHouse services the bill scales faster than the query volume, so teams end up paying substantially more each year just to hold latency where it already was. The architecture answer is a cache mesh — a cluster of NVMe-backed nodes that keep hot data resident in the query path, with S3 used as a write-only durability layer that never sits between a client and its results. The practical effect the vendor publishes is that p99 latency stays flat as a dataset grows from one terabyte to a petabyte while cost per query falls, which inverts the usual pattern where both degrade together. Clients connect over ordinary SQL through the standard ClickHouse drivers, so it is a hosting swap rather than a migration to a new query language. The pricing page is a live calculator rather than a plan ladder: you set compressed storage, memory per node and node count, pick a workload preset for real-time, observability or BI shapes, and it prices the cluster against a one-to-one comparison with other managed ClickHouse offerings. Ingress and egress are not metered. There is a free developer instance for evaluation, and the team offers a performance audit before you commit, which suits the case where you already run ClickHouse somewhere and want the comparison on your own workload rather than on a benchmark.

ObsessionDB Pros & Cons

Pros

  • +Cost-per-query improving with scale is the opposite of the usual managed-ClickHouse curve
  • +Standard SQL and drivers make it a hosting swap rather than a rewrite
  • +Free egress removes the usual hidden line item on analytical workloads

⚠️ Cons

  • Entry pricing lands in the thousands per month — not a hobby-project database
  • Benchmarks are vendor-published on their own customer workloads
  • ClickHouse-only, so it does not help if your analytics live elsewhere
