Limitations & when to consider alternatives
Known limitations
- Client-side processing. Exported applications process data client-side with Pyodide and do not require server-side components.
- Browser dependency. Preswald applications are designed to run locally in a browser rather than as native mobile or desktop applications.
- Large-data memory constraints. The get_df documentation advises considering memory limitations when retrieving large datasets.
- Restricted automatic assignment patterns. Reactive lifting supports simple name-based assignments but not attribute, subscript, or starred assignments.
Look elsewhere when
- You need native iOS or Android apps.
- You need shared workspaces with roles and invitations.
- You need a server-side application runtime.
- You need built-in model fine-tuning or training jobs.
