Solara: Pure Python web apps beyond prototypes and dashboards
summary
Solara claims to let you build large production Python web apps (not just prototypes) by running IPyWidgets on a server backed by Starlette/FastAPI and a single process with many virtual kernels, sharing memory for immutable data. It provides a declarative, component-centric API, reactive variables with hot reload and test support via pytest-ipywidgets, and a simple launch command like solara run my app.py. Users report an eight times cost reduction migrating certain apps.
