Reverse ETL for the code-first data stack.
drt syncs data from your data warehouse to external services — declaratively, via YAML and CLI.
Think dbt run → drt run. Same developer experience, opposite data direction.
pip install drt-core # core (DuckDB included)
drt init && drt run| Problem | drt's answer |
|---|---|
| Census/Hightouch are expensive SaaS | Free, self-hosted OSS |
| GUI-first tools don't fit CI/CD | CLI + YAML, Git-native |
| dbt/dlt ecosystem has no reverse leg | Same philosophy, same DX |
| LLM/MCP era makes GUI SaaS overkill | LLM-native by design |
No cloud accounts needed — runs locally with DuckDB in about 5 minutes.
pip install drt-coreFor cloud sources:
pip install drt-core[bigquery],drt-core[postgres], etc.
mkdir my-drt-project && cd my-drt-project
drt init # select "duckdb" as sourcepython -c "
import duckdb
c = duckdb.connect('warehouse.duckdb')
c.execute('''CREATE TABLE IF NOT EXISTS users AS SELECT * FROM (VALUES
(1, 'Alice', 'alice@example.com'),
(2, 'Bob', 'bob@example.com'),
(3, 'Carol', 'carol@example.com')
) t(id, name, email)''')
c.close()
