LicenseDB License Diff od capfei

LicenseDB Diff helps you identify an unknown license or exception by comparing selected text against two authoritative sources: AboutCode's ScanCode LicenseDB and the SPDX License List.

Select any block of license text on a web page, click the extension icon, and get a ranked list of the closest matches with a full word-level diff of what changed.

Features:

• Compares against ScanCode LicenseDB and SPDX, together or individually
• Choose whether to match licenses, exceptions, or both
• Ranked results with a detailed similarity breakdown: overall score, containment, cosine, token Levenshtein,
• Word-level diffs that highlight exactly which words appear only in your selection and which appear only in the reference license
• Flags exact template matches, where the text matches the license template ignoring variable fields
• Jump between changes with next/previous navigation, or collapse long unchanged passages to focus only on differences
• Copy the diff or the full reference license text to the clipboard in one click
• Direct links to the license source, plus one-click copying of the SPDX identifier
• Group results by source or rank them together
• Light and dark themes
• Configurable result count and minimum match threshold
• The license database is cached locally and can be refreshed or rebuilt on demand from the options page.
