Connect Erathos to ClickHouse

Community maintained

Erathos is an ELT platform built for control without the overhead, letting teams manage every sync job from SaaS tools and databases into the warehouse.

Overview

Erathos gives teams visibility and control over every sync job as data moves from SaaS tools, ERPs, and CRMs into ClickHouse. Instead of managing pipelines as opaque, scheduled jobs, Erathos lets you monitor and control syncs in real time, making it easier to catch issues early and keep your warehouse up to date.
