HTMLiga

HTMLiga is a web-based integrated development environment focused on authoring HTML documents and related web technologies. It provides an interactive editor with a live preview and tooling to assist beginners and professionals in building web pages.

The project originated in the early 2010s as an open-source effort to simplify HTML authoring in a browser. It evolved to support CSS and JavaScript tooling and to function offline, through a progressive web app design.

Key features:

- Real-time HTML rendering with a split-view preview

- Syntax highlighting and code completion

- HTML validation and accessibility checks

- CSS and JavaScript tooling, including linting

- Template library and project scaffolding

- Import/export of projects and assets

- Extensibility via plugins and themes

Technical overview:

HTMLiga runs primarily in the browser, leveraging modern web APIs, client-side storage, and optional WebAssembly components; it uses a plugin architecture for extensions and supports offline usage.

Reception:

In education and freelance development, HTMLiga has been noted for lowering the barrier to entry, though some critics point to performance concerns on older devices and the risk of feature bloat as a web app grows.
