Review Board provides an extension API that can be used to extend the available features across the product.
The extension API is still new and bleeding edge, and will be improved over time. If you’re interested in developing an extension, please read our Extending Review Board guide to get started.
Extensions are distributed as Python packages. These may have to be downloaded on a website, or may be distributed through the standard Python package distribution system.
In general, extensions can be installed with pip install. Please prefer to the particular extension’s documentation for installation instructions.
The Extensions page in the Administration UI lists all extensions currently installed on the system. From here, you can enable, disable, configure, or edit database entries for an extension.
Depending on the capabilities of the extension, you’ll see one or more buttons:
Enable - Enables the extension.
Disable - Disables the extension.
Configure - Opens a configuration page for customizing the behavior of the extension.
Database - Opens a page for editing the extension’s internal database. (This is an advanced feature and should only be used if you know what you’re doing.)
