An additive layer on open-source React on Rails

React on Rails Pro

Pro builds on the open-source gem with React Server Components, streaming SSR, fragment caching, and a dedicated Node renderer. The gem and npm package are public — install them and start building today. A license is only required when you deploy to production.

bundle add react_on_rails_pro

Free to build withNo token needed for development, test, CI/CD, or staging. With no license configured, Pro keeps running and logs its license status instead of ever blocking your app. Production deployments need a paid license, which includes maintainer support.

What Pro adds

Everything below comes from the open-source stack plus the public Pro gem. There is no paywall — a license covers production use and support, not access.

React Server Components

Render and stream React Server Components from Rails to ship interactive UI with dramatically less client JavaScript.

Streaming SSR

Progressively stream server-rendered HTML so the first paint does not wait on the slowest part of the page.

Fragment caching

Cache rendered React output on server-rendering paths to cut repeat render cost on your hottest pages.

Dedicated Node renderer

Run server rendering in a concurrent Node.js process for higher SSR throughput than single-threaded ExecJS.

Code splitting + bundle caching

Loadable-component code splitting with SSR-aware bundle caching for large client bundles.

Upgrade path

Three steps to build with Pro

1
Add the gem and package
Run bundle add react_on_rails_pro and add the npm package. Both are public on RubyGems and npm — no token or account required to start.
2
Turn on the features you need
Enable RSC, streaming SSR, fragment caching, or the Node renderer on the paths where they actually help.
3
Validate, then license for production
Confirm production rendering and performance on the paths that matter, then add a license when you deploy.

Friendly license model

Build now. License when you ship.

Try every Pro feature freely in development, test, CI/CD, and staging. With no license configured, Pro keeps running in unlicensed mode and logs its status — it never blocks your app.

Production deployments require a paid license, which includes support from the ShakaCode maintainers. Visit Pro pricing and sign up for current options.

Budget-constrained? Email justin@shakacode.com — we grant free or low-cost licenses in qualifying cases. Licenses from larger companies fund continued React on Rails development.
