Check whether an npm package loads with import and require in Node.js, Bun and Deno.

Published npm packages are tested on Linux amd64 / glibc with pinned runtime images. Install scripts stay disabled. Loading success does not establish functional correctness or package safety.

Search by name at https://compatlab.me/ or read the public API guide. Reads never start scans.
