Do These Packages Exist?
AI assistants sometimes invent package names. List the packages in your code and check each one against npm and PyPI before you install it.
Paste code an AI wrote, a package.json or a requirements.txt. The packages it uses are listed here in your browser; asking the npm and PyPI registries whether they exist is a separate step you start yourself.
What is sent
Package lookups are not turned on in this build, so nothing is sent anywhere. The packages found in your code are still listed below.
“Exists” only means the registry has a package with that name: it does not say the package is safe or does what the code expects. A package first published in the last 30 days is flagged because AI-invented names are sometimes registered by others afterwards. A Python import name can differ from the package that provides it (a small table of common cases is built in), so check those results by hand.
