How Shipsidekick replaced Neon with ClickHouse Managed Postgres for 10x faster queries and better reliability

Shipsidekick, a logistics platform founded in 2024 by Sawyer Bateman, migrated its Next.js and Vercel-based application from Neon Postgres to ClickHouse Managed Postgres after recurring connection-pool exhaustion, CPU saturation, slow queries, outages during peak Monday workloads, and delayed vendor support. The company moved roughly 500 GB of data over a weekend using ClickPipes logical replication, completing the initial transfer in four to five hours, while resolving a temporary partial-index issue during replication. Shipsidekick selected ClickHouse Managed Postgres for its pricing, instance configurations, bundled PgBouncer connection pooling, NVMe-backed storage, documentation, and responsive support, after also considering PlanetScale. According to Bateman, the new deployment reduced typical CPU use from 100% to 5–10%, raised cache-hit rates from 30–35% to 99%, and made queries roughly ten times faster, including a shipment-data query that fell from 80 seconds to about six seconds. The company later added safeguards and a dedicated read replica for AI-agent workloads after an unrestricted read query affected primary database performance, and it is considering moving application dashboards and other analytical workloads to ClickHouse itself.
