In their own words
Bonobo
Bonobo is a free, open-source ETL framework for Python developers building data transformation pipelines. It connects callable or iterable Python objects into directed graphs that it can visualize and execute. Data moves as streams of independent rows, with each node handling one row at a time while nodes can run in parallel. Transformations may be plain Python or transformation classes, organized as small units intended to support testing and maintenance. Built-in extractors and writers cover CSV, JSON, XML and XLS; the framework can also work with sources such as HTTP REST or SOAP APIs, filesystems, storage services, and SQL or NoSQL databases. The SQLAlchemy extension adds SQL database capabilities, while a Docker extension can run a local job with the bonobo runc command. Bonobo can also show live job status in a Jupyter Notebook. It is self-hosted, released under Apache License 2.0, and documented for small-scale data use. The documentation identifies it as alpha, so APIs may change.
Ibis
Ibis is a free, open-source Python dataframe library that provides a consistent API across more than 20 query backends. It lets users compose SQL and Python dataframe code, bringing data engineering and data science workflows together. For local dataframes, Ibis uses DuckDB by default and also names Polars and DataFusion. The project describes a workflow that can start locally and move to remote execution by changing a single line of code.
Ibis supports and tests Google BigQuery, Snowflake, Databricks Cloud, and Amazon Athena; support for those cloud backends could move to best effort if funding ends. Supported data formats include CSV, TSV, JSON, Parquet, Delta Lake, and Avro. Install Ibis with a supported backend using pip, conda, mamba, or pixi. One package distinction matters: the PyPI package named ibis is separate from ibis-framework, and the two cannot coexist in one Python environment because both use the ibis module name. Operation coverage varies by backend due to differences in SQL dialects and upstream support. The project recommends GitHub and Zulip for help, and Voltron Data offers commercial support.
