OpenFin Process Model

Overview

This article explains how the OpenFin Process Model works.

Runtime

OpenFin utilizes the Chromium process model which runs separate functional processes in isolation to create a more secure, robust architecture

Current Process Model

From v14.* and newer the OpenFin process model is as follows:

process	description
browser	Main process that coordinates all activities - in Chrome this process renders the address bar, bookmarks, tabs, etc. In OpenFin this is where the “core” runs, exposing our API’s to Applications (that are running in renderer processes). There is one Browser process per OpenFin version (or security realm)
renderer	Application code runs here - roughly equivalent to an “Application” in the OpenFin API - Sandboxed. There is typically one Renderer process per OpenFin Application, but it’s possible to create more e.g. Views with processAffinity, programmatically started Applications, etc.
gpu	Helper process that manages the GPU/accelerates UI rendering. There is one GPU process per OpenFin version (or security realm)
network-service (utility)	Helper process that owns all network requests. There is one network-service process per OpenFin version (or security realm)
audio-service (utility)	Helper process that owns video / audio. One audio-service process per OpenFin version (or security realm)

v13 and earlier
