This is well-suited for teaching and learning purposes and for users who want to experiment with Stan models without the hassle of setting up a local environment. You can edit Stan programs, provide input data, set sampling parameters, and view the results—all within your browser. You can also provide Python or R code to generate the input data (this also runs in the browser) and use Python or R code to post-process the results and generate plots. You can then share your results with others using the GitHub Gist feature. +Stan Playground is a browser-based editor and runtime environment for Stan models. Users can edit, compile, and run models, as well as analyze the results using built-in plots and statistics or custom analysis code in Python or R, all with no local installation required. This is well-suited for teaching and learning purposes and for users who want to experiment with Stan models without the hassle of setting up a local environment. You can also share your results with others using the GitHub Gist feature. While the Stan models execute in the browser (on your local machine), the compilation process requires a dedicated server. We provide a default public server for your convenience, but you can also set up your own compilation server either locally or remotely. -This project is based on [stan-web-demo](https://github.com/WardBrian/stan-web-demo) which shows how to use [TinyStan](https://github.com/WardBrian/tinystan) to build a WebAssembly version of a Stan model that can be executed in the browser.
