FAQ
What is the DuckDB Universe?
A free, searchable map of 575 projects and companies built on DuckDB: 516 open-source projects from the awesome-duckdb list (archived repos left out) and 59 companies and products that publicly say they build on or with DuckDB, each linked to that source. Updated 2026-10-26.
What are the most popular open-source projects built on DuckDB?
By GitHub stars: PyGWalker (16K stars), Kepler.gl (12.1K stars), Lance (7.2K stars), Evidence (7.1K stars), Ibis Project (6.7K stars), AliSQL (6K stars), smallpond (5K stars), Apple Embedding Atlas (5K stars).
Which companies are built on DuckDB?
Companies that state it publicly include Airbyte, Arrow, AWS, Bruin, Cloudflare, Count, Dagster, dbt, Deepnote, DeepSeek, Definite, Delta Lake, dlt, DuckDB-Wasm. Each company page links to the source where it says so.
What are the best DuckDB UIs and clients?
The most-starred DuckDB clients and UIs in the map are Preswald (4.3K stars), Online DuckDB Shell (2.2K stars), Codapi (2.1K stars), Duck-UI (646 stars), PondPilot (256 stars).
What are the most popular DuckDB extensions?
DuckDB has 29 core extensions and 267 community extensions. The most downloaded community extensions last week were stochastic (224,340 downloads), anofox_forecast (214,092 downloads), gsheets (177,154 downloads), h3 (134,768 downloads), mssql (126,633 downloads), according to duckdb.org. You install one with INSTALL name FROM community.
Can DuckDB replace Snowflake?
For a large share of queries, yes. Snowflake's own public Snowset dataset (69 million customer queries from 2018) shows the median query scanned 5 MB and 96.2% scanned under 10 GB, a size DuckDB handles on one machine. The few very large queries still benefit from a warehouse. Greybeam routes each Snowflake query to DuckDB or Snowflake based on that split.
Is DuckDB free?
Yes. DuckDB is open source under the MIT license.
How do I get my project added?
Add it to the awesome-duckdb list on GitHub (github.com/davidgasquez/awesome-duckdb). The DuckDB Universe is rebuilt from that list.
