StructuredLabs / preswald
Preswald is a WASM packager for Python-based interactive data apps: bundle full complex data workflows, particularly visualizations, into single files, runnable completely in-browser, using Pyodide, DuckDB, Pandas, and Plotly, Matplotlib, etc. Build dashboards, reports, and notebooks that run offline, load fast, and share like a document.
Why this job: matched by what the repo talks about: browser, data, workflow, bas
What it does
- Code-based. Write apps in Python, not in notebooks or JS frameworks
- File-first. One command creates a fully-packaged .html app
- Built for computation. Use Pyodide + DuckDB directly in-browser
- Composable UI. Use prebuilt components like tables, charts, forms
- Reactive engine. Only re-run what's needed, powered by a DAG of dependencies
