I’m incredibly excited about Posit’s latest announcement: Shiny Assistant! This AI-powered tool represents a significant shift in how we approach dashboard and application development, potentially revolutionizing the balance between proprietary no-code tools and code-based solutions.
Breaking Down the Innovation
What makes Shiny Assistant particularly impressive is its thoughtful architecture. Rather than trying to create yet another proprietary platform, Posit has leveraged existing open-source technologies in clever ways. The system is split into two main components:
- A Shiny server installation that manages environment secrets and API interactions
- A user-based browser interface that uses webR/Pyodide to run LLM generated code directly in their browser through Shinylive.
This architecture means you can quickly prototype and share applications without worrying about isolating the generated code on the server since code runs right in the user’s browser! The integration with existing Shinylive assets for in-browser editing and preview is particularly elegant, making the development experience smooth and intuitive.
Democratizing Shiny Development
For years, tools like Tableau and PowerBI have dominated the business intelligence space partly because of their low barrier to entry. Shiny Assistant changes this dynamic by making code-first development just as accessible. You can literally describe the dashboard or application you want in plain English, and the assistant will generate the code for you. Need modifications? Just ask! This democratization of development could significantly shift organizations toward solutions that are more flexible, cost-effective, and transparent.
Though, it’s important to note that Shiny Assistant isn’t a full-blown no-code solution. It’s more of a low-code tool that helps you get started with the code. This means that while you can quickly prototype and iterate on applications, you’ll still need some coding knowledge to build more complex features. However, the tool is a fantastic way to bridge the gap between no-code and code-based solutions, making it easier for non-developers to contribute to the development process.
Privacy and Customization
One of the most exciting aspects of Shiny Assistant is its flexibility regarding deployment. While you can use it directly through Posit’s hosted solution, the entire project is available on GitHub. This means you can:
- Deploy it with your own Claude API key instead of using Posit’s
- Keep your data secure and avoid potential privacy concerns
- Potentially integrate it with your company’s own LLM deployment
- Keep all code generation and execution in-house
- Customize the system prompts to fit your specific needs
- For example, you could integrate it with your company’s internal data, specific APIs, or custom Shiny frameworks ( Appsilon’s

- For example, you could integrate it with your company’s internal data, specific APIs, or custom Shiny frameworks ( Appsilon’s
This flexibility is crucial for organizations with strict data privacy requirements or those wanting to build on top of the existing framework.
Current Limitations to Note
While Shiny Assistant is impressive, it’s important to note some current limitations. A significant one is that R packages using CURL or web sockets currently don’t work in the browser-based environment. This is because webR doesn’t yet have a shim to handle these types of requests. This means that applications requiring API calls might need to be developed in a traditional IDE environment instead using code that is generated by going through this assistant.
Looking Forward
Now, we’re still in the early days of this tool, and there are some limitations to be aware of. However, the potential is clear. The combination of AI assistance and browser-based execution through Shinylive represents a new paradigm in application development. It maintains the power and flexibility of Shiny while making it accessible to users who might have previously felt intimidated by coding.
This tool could be particularly transformative for organizations looking to transition from expensive proprietary solutions to open-source alternatives. The ability to rapidly prototype and iterate on applications, combined with the option to fully control and customize the deployment, makes this a compelling solution for both individual developers and large enterprises.
