Experts in dynamic web interfaces with HTML

Lightweight frontend and development without complex JavaScript frameworks

Why does your project need months and a specialized frontend developer to add a simple dynamic form? HTMLMX returns the web to its fundamentals: extended HTML that works. No bundlers, no 500MB node_modules, no React learning curve. Just dynamic interfaces with reduced JavaScript that integrate seamlessly with your backend and deploy in minutes.

What is HTMX?

The silent revolution that is bringing sanity back to frontend development

HTMX is a library of just 14KB that transforms your HTML into extended HTML with attributes for making AJAX requests, handling WebSockets, and updating parts of the page with a dramatic reduction in JavaScript . Instead of building JSON APIs and duplicating logic between the frontend and backend, HTMX allows your server to directly return the HTML that should be displayed: it's the modern hypermedia approach.

It's not a new idea: it's how the web has worked for decades, updated to meet today's expectations for interactivity. Instagram, Basecamp, and GitHub use similar framework-less development approaches. The difference is that now we have the tools to do it elegantly and simply .

At Mecexis, we've been building robust backends with Django for over a decade. HTML fits perfectly with our lightweight frontend philosophy: powerful web applications where the logic resides on the server, keeping the frontend simple, fast, and maintainable. The result is dynamic interfaces that are delivered faster, cost less, and don't require two separate teams to run.

Main advantages of HTMX

Every technology decision directly impacts your budget, timelines, and long-term maintainability. These are the reasons why framework-free development with HTML is changing the way businesses build their web applications.

Drastic reduction of JavaScript: less complexity, lower costs

The most documented case is that of Contexte: they migrated from React to HTML and achieved a 96% reduction in JavaScript (from 255 dependencies to just 9), a 67% smaller codebase, and an 88% faster compilation time. Less code means fewer bugs, less maintenance, and fewer development hours. Translated into euros: cheaper projects that do exactly the same thing.

Lightweight frontend: one team, one language

With HTML, you don't need separate frontend developers specializing in React and backend developers specializing in Django. Your backend team can build complete dynamic interfaces using extended HTML . This eliminates cross-team coordination, API contracts, and synchronization issues that slow down projects.

Superior performance with simplicity

No Virtual DOM, no hydration, no megabyte bundles. HTML weighs 14KB and the browser does what it does best: render HTML. Performance is superior: pages load faster, work better on slow connections, and consume fewer device resources. The Contexte case study reported a 50-60% improvement in initial load time thanks to this lightweight frontend .

Native SEO with server-side rendering by default

Because the content is actual HTML served from the server (native server-side rendering), search engines index it perfectly without the need for JavaScript rendering. Assistive technologies work correctly. The simplicity of the hypermedia approach means there are no tricks, no special configuration: it simply works the way the web was always meant to work.

Seamless integration with Django: django-htmx

HTML and Django form an exceptionally productive combination for creating dynamic interfaces . Django renders templates with extended HTML , and HTML updates them dynamically. No intermediate REST APIs, no JSON serialization, no duplicate validations. Libraries like django-htmx make integration trivial and the resulting code extremely readable.

Framework-free development: progressive and compatible

Developing without frameworks using HTML doesn't require rewriting your application. You can add it to an existing page and improve it incrementally. It works with any backend, any template, and any infrastructure you already have. And if you ever need something more complex, HTML works seamlessly with additional JavaScript or Alpine.js for UI logic, while maintaining simplicity .

Ideal use cases for HTMX

Dynamic interfaces with HTML: where JavaScript frameworks are excessive

Enterprise applications with complex forms and dynamic validation using extended HTML
Dashboards and administration panels with dynamic, real-time interfaces
E-commerce with shopping carts, filters, and interactive searches with reduced JavaScript usage
Content platforms with infinite loading and smooth navigation using a hypermedia approach
Any project where time-to-market is critical and you need a lightweight frontend

Technical Specifications

HTML is deceptively simple on the surface thanks to its philosophy of simplicity , but it offers sophisticated technical capabilities that cover virtually any pattern of modern web interactivity.

Declarative HTTP requests: AJAX without JavaScript

Any extended HTML element can make GET, POST, PUT, PATCH, or DELETE requests simply by adding attributes. A button that updates a section of the page requires a single line of HTML, not a React component with state, effects, and handlers. It's AJAX without explicit JavaScript.

Surgical update of the DOM with simplicity

HTML lets you specify exactly which part of the page should be updated with the server's response. Replacing, appending before, appending after, deleting... all controlled through simple attributes like hx-target and hx-swap, without manual DOM manipulation. This simplicity is key to performance .

Advanced triggers for dynamic interfaces

Requests can be triggered by any browser event: clicks, changes in inputs, scrolling, time intervals, or custom events. Built-in debouncing and throttling prevent overloading the server in dynamic interfaces with real-time searches or infinite scrolling.

WebSockets and SSE: real-time without frameworks

For applications requiring real-time updates, HTMLMX natively supports WebSockets and SSE. Notifications, chats, live data dashboards—all with reduced JavaScript usage and no complex infrastructure setup. It's true framework-free development .

Extensions and Customization

The extension system allows you to add features such as confirmations before sending, loading indicators, custom error handling, and integration with third-party libraries. The architecture is open, well-documented, and keeps the frontend lightweight .

History API: SPA navigation with extended HTML

HTML can update the browser URL and manage browsing history, providing the experience of a Single Page Application without technically being one, thanks to its hypermedia approach. The back button works correctly, and URLs are shareable and bookmarkable, with all the performance benefits of server-side rendering.

1 Deep mastery of Django and django-htmx: HTML is only half the equation. The other half is a backend that efficiently serves extended HTML , manages state correctly, and scales when needed. With over a decade of experience in Django and django-htmx , we've built the solid foundation upon which HTML can shine. We're not a frontend agency experimenting with backends; we're backend experts who have found in HTML the perfect complement to a lightweight frontend .
2 Architecture with simplicity designed for the long term: The simplicity of HTML can be deceiving. Without a well-designed architecture, it's easy to end up with spaghetti code that's difficult to maintain. We apply proven patterns to organize partial views with extended HTML , manage state between requests, and structure projects that scale in complexity without sacrificing readability.
3 Progressive migration: from SPA to lightweight frontend: Do you have a React or Vue application that has become unmanageable? There's no need to rewrite it from scratch. We design incremental migration strategies toward a lightweight frontend where HTML gradually replaces components with reduced JavaScript , allowing you to validate the approach risk-free and without halting the development of new features.
4 Complete stack with framework-free development: HTML rarely exists in isolation in our development without frameworks . We combine it with Alpine.js for local interactivity, Tailwind for styling, django-htmx for deep integration, and deploy it on production-ready cloud infrastructures. You deliver complete projects with dynamic interfaces , not pieces you need to assemble yourself.
