Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
HTMX
- Best suited for server-rendered architectures, not pure client-side SPAs
- Limited client-side state management capabilities compared to frameworks
- Smaller ecosystem with fewer third-party libraries and tools
- Learning curve for developers from JavaScript framework backgrounds
Alpine.js
- Not suitable for complex single-page applications with heavy state management
- Limited ecosystem compared to larger frameworks like React or Vue
- Smaller community means fewer tutorials and third-party libraries
- Performance may suffer in highly interactive applications with frequent state updates

Answered from the vendors’ own pages
HTMX: How big is the HTMX JavaScript library?
HTMX is only 16 kilobytes minified and gzipped with zero external dependencies.
SourceAlpine.js: Is Alpine.js suitable for complex applications?
Alpine.js is designed for progressive enhancement and adding interactivity to server-rendered applications. Complex single-page applications are better served by full-featured frameworks.
SourceHTMX: Can HTMX work with JSON APIs?
While HTMX is optimized for HTML responses, it can work with JSON through additional configuration and response handling.
SourceAlpine.js: How does Alpine.js compare to jQuery?
Alpine.js is the modern successor to jQuery, emphasizing declarative attributes for interactivity rather than imperative DOM manipulation.
SourceHTMX: Does HTMX support real-time features like WebSockets?
Yes, HTMX includes support for WebSockets and server-sent events for real-time bidirectional communication.
SourceAlpine.js: Can Alpine.js be used alongside other frameworks?
Yes, Alpine.js can be used to add interactivity to specific components within server-rendered applications without conflicts.
