How Blacksmith paired Postgres and ClickHouse for fast CI and real-time observability

Blacksmith, founded in 2024, aims to enhance Continuous Integration (CI) processes by offering a faster and more observable alternative to GitHub Actions, serving over 600 organizations and handling 9 million monthly jobs. By providing features such as step-by-step visibility, caching insights, and global log search, Blacksmith helps developers diagnose and resolve CI issues more effectively. To support its advanced analytics and observability needs, Blacksmith transitioned from Postgres to ClickHouse Cloud, leveraging tools like ClickPipes and the Postgres CDC connector for real-time data streaming without complex ETL processes. This setup enables fast and flexible analytics, powering both engineering and go-to-market strategies. Blacksmith also benefits from ClickHouse Cloud's innovative features like Ask AI, which simplifies SQL querying, and the Model Context Protocol (MCP) server, enhancing accessibility and intelligent workflow development. As Blacksmith continues to grow, ClickHouse remains integral to its operations, offering a robust solution for modern companies looking to optimize CI and data analytics workflows.
