Knockout is a JavaScript library that helps you create rich, responsive, and maintainable user interfaces. It follows the MVVM (Model-View-ViewModel) architectural pattern, allowing you to separate your UI logic from your business logic. With Knockout, you can easily bind your UI elements to data models, and any changes in the data will automatically update the UI.

Fight!

Popularity

Knockout has been around for a longer time and has a larger community and user base compared to Preact. However, Preact has gained popularity in recent years due to its smaller size and compatibility with React APIs.

Size

Preact is significantly smaller in size compared to Knockout. Preact is a lightweight alternative to React and aims to provide a similar API with a smaller footprint. Knockout, on the other hand, has a larger codebase and includes additional features like two-way data binding.

Compatibility

Knockout is a standalone JavaScript library that can be used independently. It has its own templating engine and data binding capabilities. Preact, on the other hand, is designed to be compatible with React. It provides a similar API and can be used as a drop-in replacement for React components.

Performance

Preact is known for its excellent performance due to its smaller size and optimized rendering. It is faster in terms of initial load time and rendering compared to Knockout. Knockout, however, provides two-way data binding out of the box, which can be beneficial for certain use cases but may impact performance.

Developer Experience

Both Knockout and Preact have good developer experiences. Knockout provides a declarative syntax for data binding and a clear separation between view and view model. Preact, being compatible with React, allows developers to leverage their existing knowledge of React and its ecosystem.

Community and Ecosystem

React has a much larger community and ecosystem compared to both Knockout and Preact. React has a vast number of libraries, tools, and resources available, making it easier to find support and solutions to common problems. Knockout has a smaller but dedicated community, while Preact benefits from the React ecosystem.
