Overview
HTML-over-the-wire stack from 37signals: Turbo (server-rendered partial updates) plus Stimulus (sprinkles of JS). Skip the SPA, ship the monolith.
What you get
Hotwire builds modern web apps with little JavaScript by sending HTML instead of JSON over the wire.
Where it fits in your stack
Templates render on the server, so Hotwire works with a server-side framework in any programming language.
Who it’s for
Hotwire (Turbo + Stimulus) suits teams that want this specific capability without rolling it from scratch. When evaluating, look at the community, hosting story, escape hatches, and how the costs scale as the project grows.
Pricing & licensing
Hotwire (Turbo + Stimulus) is open source / free to use. Hosted offerings or commercial add-ons are documented on the project site.
