Title: Dear HN,<p>I am Riwaj, the cofounder of dstack.ai (https:&#x2F;&#x2F;github.com&#x2F;dstackai).<p>A few months ago, we built an online service that allows users to publish data visualizations from Python or R.  The idea was to build a tool that did not require additional programming or front-end development for publishing data visualizations. 
Such a code can be invoked from either Jupyter notebook, RMarkdown, Python, or R scripts. Once the data is pushed, it can be accessed via a browser.<p>Open-sourcing dstack:
During our customer discovery phase, we realized that dstack.ai should integrate a lot more open source data science frameworks than we integrated ourselves. For example, as a user, I want to push a matplotlib plot, a Tensorflow model, a plotly chart, a pandas dataframe, and I expect the presentation layer to fully-support it. Supporting all types of artifacts and providing all the tools to work with them solely seems to be a very challenging task.
With this, we open-sourced the framework. Now you can build dstack locally, and run it on your servers, or in a cloud of your choice if that’s needed.
More details on the project, how to use it, and the source code of the server can be found at the https:&#x2F;&#x2F;github.com&#x2F;dstackai&#x2F;dstack repo. The client packages for Python and R are available at the https:&#x2F;&#x2F;github.com&#x2F;dstackai&#x2F;dstack-py and https:&#x2F;&#x2F;github.com&#x2F;dstackai&#x2F;dstack-r correspondingly.<p>What’s next:
User callbacks-  so that application shows not just pre-calculated visualizations but also can fetch data from a store and process it in real-time. 
ML models- so that data scientists can publish a stack which binds together a pre-calculated ML model and user parameters
Use cases- Support specific use cases that help data scientists to build data science models into data applications as fast as possible.<p>We would be happy to get your feedback on the open-source framework and also get your opinion on what kind of use cases can be built on top of the framework? 
Thank you.
