Zero-True

Zero-True is an open-source Python and SQL reactive computational notebook platform designed for data scientists and data teams. Unlike traditional notebooks, Zero-True uses reactive cell execution — changes update the notebook display in real time with no hidden state — and includes a rich UI library powered by Vuetify components for creating interactive, shareable data applications. Users can build dashboards, visualizations, and data apps using familiar Python and SQL, then publish them to a cloud URL with a single command. The platform supports multiple cell types, Plotly chart integration, and customizable layouts. Zero-True is installable via pip and runs locally on port 1326, targeting teams that want to move from raw notebook experiments to polished, shareable data applications without switching tools. The project is open-source under the Apache-2.0 license and maintained on GitHub.
