Sails
Sails is a web framework that builds on WebObjects, Rails.
Objective-Smalltalk
Objective-Smalltalk supports the REST architectural style directly, so the model can already be REST-structured.
The web framework therefore has less to do, it just needs to handle templating, HTML generation and interaction.
HTMX
HTMX provides interactivity to web applications without needing heavy-weight front-end framworks.
HTMXNative
HTMXNative runs HTMX-based web applicions inside a native WebView without the need for a web-server.
