+  But Shiny apps aren’t toy apps–Shiny's powerful [reactive framework](/docs/reactive-foundations.qmd) and [extensible components](/docs/custom-component-one-off.qmd) mean your applications can evolve alongside your needs.
   Start simple, then [customize and scale](https://gallery.shinyapps.io/aws-community-builders-dashboard/) without switching frameworks.
 
 - **Plays well with others**<br>
   Bring to life the Python packages you know and love with Shiny.
   Turn polars and pandas data frames into [dynamic data grids](/components/outputs/data-grid/). Breathe interactivity into any [matplotlib](/components/outputs/plot-matplotlib/) or [seaborn](/components/outputs/plot-seaborn/) plot.

 - **Deploy with confidence**<br>
   When it’s time to put your Shiny app on the web, you can choose to deploy [on your own servers](/get-started/deploy-on-prem.qmd), on our [hosting services](/get-started/deploy-cloud.qmd), or even [serverless with shinylive](/get-started/shinylive.qmd).
