# JBrowse 2

JBrowse 2 is a pluggable, open-source genome browser. It runs as a web app, a
desktop app (Mac, Windows, Linux), and as embeddable React components. It offers
linear, circular, dotplot, synteny, and spreadsheet views, with track types for
alignments (BAM/CRAM), variants and structural variants, quantitative/coverage,
and more, plus a grammar of graphics that plots any file's fields from config.

The web app is "static-site compatible": it is pure client-side JS, CSS, and
HTML, so it can be hosted anywhere with no server. The stack is React,
TypeScript, and @jbrowse/mobx-state-tree.

## Installing and running

- Desktop app: [downloads](https://jbrowse.org/jb2/download/)
- Web app: [web quickstart](https://jbrowse.org/jb2/docs/quickstart_web/)
