PlayCode's compiler is optimized for speed. Initial compilation takes 100-500ms depending on project size. Incremental builds (when you edit code) complete in 20-50ms. That's often faster than running a local Node.js bundler because everything runs in memory with no disk I/O.

Yes! PlayCode supports the entire npm ecosystem. Just import any package like React, Vue, Lodash, or Axios, and our compiler fetches and bundles it automatically. No npm install needed. Our intelligent caching makes subsequent imports instant.

PlayCode works offline once loaded. The compiler runs entirely in your browser using WebAssembly, so you can keep coding without an internet connection. Your code is saved locally and syncs when you're back online.
