SweatStack

The demo is deployed to SweatStack Pages (pages.sweatstack.dev): Zero-config static hosting for SweatStack powered apps. This is free for now while I figure out what to do with it. (pages you publish now will be free forever).
You can use outside of an AI coding environment (CLI and web).

The demo uses SweatStack Skills to make Claude Code smarter. But these skills are not Claude Code specific, you can them in any AI coding environment. Learn more: github.com/SweatStack/s...

SweatStack + Claude Code = 🚀
Use SweatStack together with Claude Code to go from idea to published app in just a few minutes! Demo:

Introducing SweatStack Skills: Install once, and your AI assistant knows everyting about SweatStack's API, auth flows, and data formats. No more pasting documentation into chat or explaining the same things repeatedly. Just describe what you want to build.

Even with Claude Desktop's code execution limitations, it can already analyze basic workout data from SweatStack. This proof-of-concept shows a path forward: As AI tools evolve, tools like this will become proper data analysis assitants for anyone interested. Small steps!

Now AI assistants can access SweatStack data directly! Watch Claude Desktop pull my activity data and analyze it without writing a single line of code!

The SweatStack Python library has built-in support for Streamlit, making it incredibly easy to start building your dream app.

Express Login gives you access to your data in Python in under 30 seconds at SweatStack.run!

New: SweatStack Express Login lets you register by simply connecting a data source - no account setup needed.
This drastically improves onboarding for 3rd party applications that are powered by SweatStack.

Sneak peek 😎

Usecase is similar but different from the SweatStack Console: For quick explorations, the Console is slightly nicer to work with because it's a proper REPL that keeps a Python session running. However, for larger scripts that you want to keep and/or share, sweatstack.run is the way to go.

It automatically authenticates with your SweatStack account using OAuth2/OpenID and installs any dependency you import.

As an alternative to the Console, I also deployed a variant on @pydantic.dev 's pydantic.run : sweatstack.run
