Preact
Preact is a 3KB alternative to React with the same modern API, aimed at performance and tiny bundles. A compatibility layer lets most React code run unchanged.
Pros
- Tiny footprint. About 3KB versus React's much larger runtime. 0
- React-compatible. preact/compat runs most React libraries unchanged. 0
- Fast. Smaller runtime means quicker load and render. 0

Cons
- Compat edge cases. Some React libraries misbehave under the shim. 0
- Smaller community. Far fewer resources than React proper. 0
- Feature lag. Trails React on the newest APIs. 0
