Check software license compatibility and identify potential conflicts before combining or distributing code.
About License Compatibility Checker
A free, open-source developer tool for analyzing compatibility between software licenses. It helps developers identify copyleft requirements, attribution obligations, source-code disclosure requirements, commercial-use restrictions, and other potential licensing conflicts. The analysis is directional and deterministic, covering common scenarios such as dependencies, modified code, binary distribution, SaaS, proprietary software, internal use, resale, and source-code acquisitions. Informational guidance only; not legal advice.
