How can we map a license string found in the wild automatically and deterministically? LicenseLynx is the answer to that!

We collect and match license strings found from SPDX, ScanCode LicenseDB, and OSI License List to its canonical identifier. But this is just the starting point. The most valuable data comes from the community with custom aliases for license identifiers which are not present in the license databases or license lists.

Key Features
