MiniLake Is a Local Databricks API Emulator with SQL, Delta Lake and Spark

MiniLake is an open-source local emulator of the Databricks API that runs on your machine, allowing developers to test Databricks workflows without cloud costs or credentials. It provides real SQL execution via DuckDB, genuine Delta Lake file handling, and actual Spark job execution in containers, along with Unity Catalog support and compatibility with Databricks tools like the SDK, CLI, Terraform, and Asset Bundles. The emulator includes a built-in SQL workspace, MCP server for LLM agents, and has been thoroughly tested against the real Databricks SDK.
