About 32-bit USEARCH
The 32-bit version meets the needs of most users. It is compatible with 32-bit and 64-bit operating systems. The main limitation is that a maximum of 4Gb RAM can be used (2Gb under Windows). See memory requirements for more information. A 64-bit version is available for very large datasets, this requires a paid license even for non-profit / academic use.

The 32-bit version of USEARCH is licensed at no charge for individual use. The license allows commercial use, but does not allow re-distribution of the binary.  If you complete the form below, a download link will be emailed to you.A no-charge 32-bit license is also available for university compute clusters.
The email list has been discontinued. In future, I will tweet about updates and other USEARCH news such as new preprints and published papers. If you don't use twitter, you could use a service such as changedetection.com which can send you an email every time this page changes.

I understand and accept the license agreement (required).
