About Qwik
Qwik is a web framework that aims to make pages interactive quickly. It uses a technique called resumability, which avoids the full hydration step that many frameworks need before a page responds.
What it does
The server sends HTML along with the information needed to resume the app in the browser. Code is loaded lazily as the user interacts with a part of the page, so only the code for that action is downloaded. The framework is built on JSX and component ideas familiar from React, and it includes a dev server and testing setup.
Key features
- Resumable apps that skip full hydration
- Lazy loading of code on interaction
- Vite dev server with Vitest and Playwright testing
- Styling with Tailwind or PostCSS
Who it's for
Teams that care about page load speed and time to first interaction, such as content sites and product pages on a busy network. It also suits React developers who want to try a different loading model without learning a new syntax.
Pricing and good to know
Qwik is open source under the MIT licence and free to use. The framework can deploy to Vercel, Netlify, Deno, Cloudflare and Express servers, though each host has its own setup. Resumability is a different model from hydration, so review how your existing components behave before a migration.
