What it is

Marko is an HTML-based templating engine that compiles templates to CommonJS modules, supporting streaming, asynchronous rendering, and custom tags. It's designed for high performance in server-rendered applications.

Marko stands out with its streaming and asynchronous rendering capabilities, making it ideal for high-performance web applications where efficient data handling is critical.

When it fits — and when it doesn’t

A good fit for

  • Teams building high-performance web apps who need streaming and async rendering capabilities.

  • Developers looking to extend HTML syntax for more expressive templates.

Look elsewhere if

  • Projects requiring real-time data updates without full page reloads, as it focuses on server-rendered content.

  • Applications that do not require or benefit from the performance optimizations provided by Marko.

Known weaknesses

Each one links to the public issue, changelog or docs page it came from, where we have one.

  1. 01

    Limited community support and small user base

    Few active contributors and limited third-party resources

  2. 02

    Complex setup for beginners

    Requires understanding of CommonJS modules, streaming concepts, and custom tag creation

  3. 03

    Documentation is sparse and not beginner-friendly

    Lack of comprehensive tutorials and examples for common use cases

  4. 04

    Performance benefits may be negligible in non-server-rendered applications

    Streaming and asynchronous rendering optimizations are less impactful without server-side rendering

What it does well

  • Streaming and asynchronous rendering capabilities.

  • Custom tag support for extending HTML syntax.

  • Compilation to CommonJS modules for performance.
