# Check your lockfile: What do you actually need to upgrade?

Drop in a lockfile. It’s read in your browser and never uploaded; only package names and versions are checked, against every known Advisory. You get the shortest list of upgrades that clears the most.

Drop your lockfile here, or choose a file

package-lock.json · npm-shrinkwrap.json · pnpm-lock.yaml · yarn.lock · bun.lock · composer.lock · requirements.txt · poetry.lock · uv.lock · Pipfile.lock · Cargo.lock · go.sum · go.mod · Gemfile.lock · mix.lock · packages.lock.json · gradle.lockfile

Read in your browser. The file never leaves this page.
