High-throughput search and clustering

USEARCH is a unique sequence analysis tool with thousands of users world-wide. USEARCH offers search and clustering algorithms that are often orders of magnitude faster than BLAST.
 
Improved productivity and insights
USEARCH combines many different algorithms into a single package with outstanding documentation and support. This cuts your learning curve, reduces the number of steps you need to take for a given task, and slashes compute times. USEARCH will encourage you to explore your data, enabling new insights and suggesting new analyses that you might not have tried with slower tools.
 
Free for most users
Licenses to use 32-bit USEARCH are offered at no charge for all users, including commercial. You can download the 32-bit version here.
