## What it is
Zaplib is an open-source Rust/WebAssembly framework for speeding up web applications by incrementally porting slow JavaScript code to Rust. It includes a JS-Rust bridge, a standard library, GPU-based 2D/3D rendering, and UI components.

## Use cases
- speed up slow javascript code in a web app
- port performance-critical functions from js to rust
- run rust code in the browser via webassembly
- build gpu-accelerated 2d and 3d rendering in the browser
- incrementally migrate a javascript web app to rust
- build highly interactive performance-intensive browser tools

## When to choose
- you have a performance bottleneck in javascript that rust/wasm could fix
- you want incremental adoption rather than a full rewrite
- you need gpu-based rendering for highly interactive web tools

## When to avoid
- you need an actively maintained library with ongoing support
- you are starting a new project from scratch
- your app does not have performance-critical hot paths
- you want a large community and ecosystem

## Facets
- artifact type: framework
