LicenseChart

LicenseChart simplifies complex legal decisions by visualizing license compatibility. Our interactive tools help developers understand which licenses work together and identify potential legal risks in their open source projects.

We focus on making open source compliance accessible to everyone - from beginners choosing their first license to enterprises managing complex codebases.

We support all major open source licenses including:

• MIT
• Apache 2.0
• GNU GPLv3
• BSD 2-Clause
• BSD 3-Clause
• GNUGPLv2
• Apache 1.1
• Eclipse
• LGPLv3

Our support continuously expands as we prioritize community requested licenses.

Our compatibility engine is based on:

• Formal analysis of license texts
• Cross-referencing with OSI and FSF standards
• Inputs from legal experts in open source compliance

For complex use cases, we recommend consulting legal professionals while using our tools as a decision support system.

We collect:

• Anonymized license comparison statistics
• Broad device information (OS, browser type, viewport dimensions)
• IP addresses (stored ≤12h)

No personally identifiable information is tracked. All session data is purged monthly. See our Privacy Policy for full details.
