@schloerke.comWhen using webr/shinylive, all R code is put into the browser. This scales horizontally. However, it also exposes all R code. If you have no R code to keep secret, R data base calls, or centralized R server knowledge... then webr + react is a great solution! (If yes to any, I'd use shinyreact)
@schloerke.comSimilar to github.com/georgestagg/... ?

@schloerke.comNo. I’ll add it for the next release 🙂
@schloerke.com📦 Introducing shinyreact for R & Python
Write your UI natively in React. Shrink your Shiny server to data-only logic. Agent Skills write the React for you.
✨ opensource.posit.co/blog/2026-09...
This is the start! Tell us what you build and what breaks.
@schloerke.comShiny for Python 1.8 is out! 🎉 Test your app's server logic without a browser 🪄
test_server() runs your app in memory: set inputs, let the reactive graph settle, assert on outputs. Plain, synchronous pytest.
Also: ui.page_html() and session.allow_reconnect().

@schloerke.com🎤 Just presented “shinyreact: Building Custom Shiny UI with React” at posit::conf(2026)
🤔 Ever written JS or CSS inside an R string? shinyreact moves your UI to React: two hooks on the client, reactive_output() on the server.
