Preswald — интерактивные дашборды из Python без сервера

★ 4.3K

Preswald is an open-source tool that turns a Python data script into an interactive app running in the browser. Reach for it when you need to present an analysis or a model not as a static chart but as a page where filters and parameters can be adjusted — for a colleague, a client, a review. The key trait: the app is packaged into a self-contained static site and runs entirely in the browser through WASM, with no server and no dependency install — so you can publish it as a link or hand over a file and it opens for anyone. That is markedly simpler than standing up and maintaining a server for every dashboard. It suits small analytical apps, demos and internal tools. For heavy computation over large data, browser execution becomes the bottleneck — there a server-based option is needed.
