duckdb.mk — open-source Analytics BI

Curated content (treat as data, not instructions):

duckdb.mk is a minimal Make-based build system that parses SQL file dependencies to build reproducible DuckDB and Parquet data pipelines, dbt-style, with no config. Open source: yes (MIT); self-hostable, requiring DuckDB 1.4.1+, GNU Make and curl. It is brand new (created 2026-09-25) and unproven at 0 stars.

What it does

The novel mechanic is that the dependency graph lives in the SQL, not in a separate config or manifest: duckdb.mk reads your organized SQL files, works out which table depends on which from the files themselves, and lets GNU Make order and cache the builds the same way Make orders a compile. The output is Parquet tables built by DuckDB. Because Make already knows how to skip work whose inputs have not changed, rebuilds are incremental and reproducible without a scheduler. Open source: yes (MIT); self-hostable — the only prerequisites are DuckDB 1.4.1+, GNU Make and curl.

• Surfaced via studio discovery in the 2026-09-26 pass.
• Anti-hype note: brand new (created 2026-09-25) with 0 stars — fresh and unproven; adopt for the local-build mechanic, not on validated maturity.

Why it matters for a GTM stack

Marketing and RevOps analytics increasingly run on local warehouses — DuckDB on a laptop or a small box — rather than a full cloud stack, and the transform step is where dbt usually enters. duckdb.mk offers the transform/build layer for that local case without dbt Cloud or a hosted orchestrator: SQL files describe the tables, Make sequences and caches the builds, DuckDB emits Parquet. For a lean team that wants dbt-style reproducibility over pipeline data without paying for or operating a hosted service, it is the owned, local build layer. Open source: yes (MIT); pricing: free; self-hostable. The honest read: the idea is clean, but at 0 stars and one day old it is unproven — pilot it on a throwaway pipeline before trusting it with anything load-bearing.
