Phovea is a framework for quickly developing bioinformatics visualization applications on the web. Phovea can be used as client-only Javascript library, or as a tightly coupled client-server system. Phovea provides datatypes and basic visualization for genomic data, and it provides infrastructure for managing data, synchronizing views, and tracking user actions.

All core client-side code in Phovea is written as TypeScript, which helps avoid errors which loosely-typed Javascript is prone to. Server-side code is written in the light-weight Flask framework for Python.

Phovea is created and maintained by the Caleydo Team, which has used the ideas behind Phovea to create a number of tools.
