Welcome to CRISPREvo!
CRISPREvo is a webserver designed for CRISPR evolutionary analysis. It helps you move from sequence data to interpretable CRISPR insights.
Retrieve sequences, detect and prepare CRISPR arrays, infer phylogenetic relationships, compare spacer patterns, search for potential spacer targets, and compose array visualization.
This webserver is free and open to all users and does not require a login.
