Elastic compute over object storage, transactions, automatic schema evolution, git-like data branching for safe experiments, and sandboxed Python UDFs. Try it locally from Python with the databend-driver package or run the full warehouse in Docker. ★~9.5k.","theCatch":"The README now positions it as an enterprise warehouse for AI agents, and the recommended start is Databend Cloud (free to start, commercial beyond that); self-hosting a cluster is more work. Smaller ecosystem than ClickHouse or DuckDB. Releases are frequent nightly-style builds, so pin versions.","verdict":"A Snowflake-style warehouse you can run yourself — compare with ClickHouse before choosing.","addedAt":"2026-10-18","featured":false,"domain":"Databases","subSpecialty":"Data","subcategory":"Analytics & Time-series","tags":["self-host","permissive","vector","active"],"capabilities":[],"surfaces":["Self-host"],"ecosystem":["Multi-platform"],"licenseModel":"Apache-2.0","githubStars":9471,"starsPerWeek":30,"access":"free","archived":false,"repo":{"createdAt":"2020-10-10","pushedAt":"2026-10-19","license":"Apache-2.0","archived":false,"checkedAt":"2026-10-19"}},"related":[{"slug":"supabase","name":"Supabase","tagline":"Open-source Firebase alternative built on Postgres"},{"slug":"turso","name":"Turso","tagline":"SQLite at the edge with libSQL"},{"slug":"redis","name":"Redis","tagline":"The in-memory data store everyone uses"},{"slug":"upstash","name":"Upstash","tagline":"Serverless Redis and Kafka"},{"slug":"pinecone","name":"Pinecone","tagline":"Vector database for AI applications"}],"links":{"self":"/api/gems/databend","html":"/gems/databend","markdown":"/gems/databend.md","category":"/api/gems?category=databases","categoryPage":"/stacks/databases"}}
