Compose Sites: How to Build Web Apps with Kotlin

The Rise of Compose Sites: How Modern Web Development Learned to Build Faster

Remember the old days of web development? Building a website meant wrestling with convoluted layout floats, hand-coding repetitive HTML for every single page, and spending hours trying to get things to look right across different browsers. Even as frameworks evolved, developers often found themselves drowning in configuration files, boilerplate code, and fragmented workflows.

Enter the era of Compose Sites.

Driven by the philosophy of modularity, declarative design, and component-based architecture, compose sites are transforming how we conceptualize, build, and deploy digital experiences. Whether you are a seasoned engineer or a no-code creator, understanding this paradigm shift is the key to mastering the modern web.

What Exactly is a “Compose Site”?

At its core, a compose site is a website built by composing independent, reusable, and self-contained components rather than authoring monolithic pages.

Instead of writing a static page from scratch, developers and creators snap together functional building blocks—hero sections, dynamic feeds, interactive calculators, and navigational menus—like digital Lego bricks.
