Like, literally, in the browser: kana leverages web technologies such as WebAssembly to efficiently perform the relevant computations on the user{\textquoteright}s machine, avoiding the need to provision and maintain a backend service. The application provides a streamlined one-click workflow for all steps in a typical scRNA-seq analysis, starting from a count matrix and finishing with marker detection. Results are presented in an intuitive web interface for further exploration and iterative analysis. Testing on public datasets shows that kana can analyze over 100,000 cells within 5 minutes on a typical laptop.Competing Interest StatementThe authors have declared no competing interest.},

 **kana** is a web application for single-cell RNA-seq data analysis that works directly in the browser.
 That's right - the calculations are performed client-side, by your browser, on your computer!
 This differs from the usual paradigm of, e.g., Shiny applications where data needs to be sent to a backend server that does the actual analysis.
