Description
CompatLab checks whether an exact npm package version loads on Node.js, Bun and Deno. Compare import, require and exported-subpath results from the same prepared dependency snapshot. Public reports include pinned runtimes, coverage and recorded errors. Free and open source, with no account required. Checks run on Linux amd64 with install scripts and execution network disabled. A loading pass does not prove application correctness.

Could you build this?
Partial While presenting matrix comparison reports is easy, running isolated multi-runtime (Node, Bun, Deno) sandbox execution pipelines securely and reliably requires specialized infrastructure.
What it would actually take: The system requires an isolated sandboxing runner architecture (e.g., lightweight Firecracker microVMs or Docker containers) that pulls npm packages, executes multi-runtime import/require tests under tight memory and CPU constraints, and captures stdout/stderr. Key challenges include untrusted code execution security, managing disk caching for millions of npm packages, and handling native C/C++ bindings across diverse runtimes.
