JBrowse is a genome browser with almost entirely AJAX-based interfaces. JBrowse renders most tracks using client side JavaScript and JSON as its data transfer format. JBrowse is currently under development by the Ian Holmes Lab at UC Berkeley. It is expected to have a production release in 2009. Most development has been done by Mitch Skinner. JBrowse was formerly known as GBrowse 3. However, this name was changed to JBrowse to avoid confusion: JBrowse is an alternative to GBrowse, not a successor.

It is very fast and scales well to large datasets. JBrowse is javascript-based and does almost all of its work directly in the user's web browser, with minimal requirements for the server.


  • Fast, smooth scrolling and zooming. Explore your genome with unparalleled speed.
  • Scales easily to multi-gigabase genomes and deep-coverage sequencing.
  • Supports GFF3, BED, FASTA, Wiggle, BigWig, BAM, VCF (with tabix), REST, and more. BAM, BigWig, and VCF data are displayed directly from the compressed binary file with no conversion needed.
  • Very light server resource requirements. In fact, JBrowse has no back-end server code, just tools for formatting data files to be read directly over HTTP. Serve huge datasets from a single low-cost cloud instance.ets from a single low-cost cloud instance. +
