About Streamliter

Streamliter let's you create Streamlit apps entirely in your browser. You can create, edit, and preview your app in real-time, without the need to install any software. Streamliter is perfect for prototyping, sharing, and collaborating on data science projects.

How It Works

Streamliter uses stlite to make it possible to write and run streamlit apps in the browser. Streamlit is a popular open-source framework that allows you to build interactive web applications using Python. With Streamliter, you can write your code in the browser and see the results instantly. You can also share your app with others by sending them a link to the preview.

You can have up to 5 apps saved under your account for free. For unlimited branding-free apps and other functionalities, check out the Streamliter Pro subscription.

Running Python in the Browser comes with some limitations. Most of the Python standard library works, except from some modules. The following modules can be imported, but are not functional due to the limitations of the WebAssembly VM: multiprocessing, threading, and sockets. There are also some limitations to streamlit itself due to the stlite implementation, which can be found here.
