Luigi alternative — Luigi vs Skippr
Luigi is an Apache-2.0 batch workflow library from Spotify. You declare Task classes with requires, output, and run; a central scheduler coordinates workers. Latest on PyPI is 3.8.1 (7 May 2026). Python 3.10 through 3.14. There is no SaaS SKU and no first-party Iceberg writer. CDC is a task you author. Targets are files, S3, or a database you wrap. This is not Iceberg ∪ WAL you query in one binary.
Skippr is an open Streamhouse you run as one Rust binary. Write skippr.yml (or the same thing in Python), discover, sync. You query live state over Iceberg ∪ WAL, and the history is ordinary Iceberg in your bucket. No central scheduler process for ingest. ELT into a warehouse is one path, not the product.
| Feature | Skippr | Luigi |
|---|---|---|
| Deploy | Single Rust binary, your VPC or on-prem | Scheduler + workers you run. No managed cloud |
| Schema | In-stream evolution, sibling columns | Target paths. No Iceberg schema of its own |
| Storage | Open Iceberg on Parquet you own | Whatever Target you implement |
| CDC | Log-based; fails closed if the dest cannot honour | A task you author. Luigi is the schedule |
| Query | skipprd query on Iceberg ∪ WAL; history in any Iceberg engine | After run finishes. Visualiser shows the DAG |
| Pricing | Free self-hosted engine | Apache-2.0. You pay the machines. |
What Luigi is good at
Python tasks with explicit outputs, so a batch graph does not rerun work that already landed. That is the product. The central scheduler and the visualiser are why some shops still run Luigi next to cron. If the job is "this task after that target exists," that is a real product.
Where the job is wider
Luigi is a batch scheduler. It is not a Streamhouse. There is no Iceberg ∪ WAL. There is no skipprd query on in-flight lake rows. Iceberg still starts in PyIceberg or Spark inside run. Postgres CDC still starts in Debezium or skipprd. Skippr will not replace luigid or your existing Task graph.
The scheduler process and worker hosts are the ops. Skippr will not run Luigi. Airflow, Prefect, and Dagster are separate pages.
If the job is "Luigi we already staff," Luigi is the narrower tool. If the job is live SQL on Iceberg you run, the task graph was never that.
Getting started
Install skipprd from the install guide, or pip install skippr. The three tabs write the same skippr.yml. Then discover, sync, and query.

Choose Luigi if you want a Python batch scheduler, and Iceberg or CDC as tasks you already write is enough.
Choose Skippr if you want one binary, live SQL on Iceberg ∪ WAL, and files that stay yours. Skippr will not run Luigi.
