MiniLake Is a Local Databricks API Emulator with SQL, Delta Lake and Spark
Summary
MiniLake is an open-source local Databricks API emulator that provides real SQL, Delta Lake, and Spark execution on a developer's machine. It exposes the Databricks REST API locally, allowing testing without cloud accounts or API keys, and includes Unity Catalog support, Delta Lake integration, and MCP tooling for agents. The project emphasizes CI-friendly, air-gapped operation with real engines running behind a Databricks-like API surface.
