On July 26, 2023, FingerprintJS transitioned its licensing from MIT to Business Source License (BSL 1.1) to support fair usage and sustainability while continuing to offer the source code for non-commercial purposes. This change requires businesses using FingerprintJS in production to obtain a commercial license or migrate to the Fingerprint device intelligence platform, aiming to curb the use of the software in production without compensation. Version 4.0.0 of FingerprintJS introduces new features, such as Apple Pay support detection and compatibility with Safari 17, enhancing identification accuracy. The license shift seeks to protect the open-source community, encourage commercial partnerships, and maintain the availability of FingerprintJS for personal and exploratory use.
