A viewer for Parquet, SQLite, and Avro files in JupyterLab.
Check out our new JupyterLab extension: Arbalister. 🏹
Built upon Apache Datafusion, @jupyter.org , and @arrow.apache.org , it lazily fetches rows so that you can view files larger than memory!

JupyterLite now supports any-llm-gateway as a backend for its AI static front-end.
any-llm-gateway routes LLM requests through a single gateway rather than tying usage to one provider.
