For the product version of MATLAB Web App Server:
The product version of MATLAB Web App Server can support multiple versions of MATLAB Runtime simultaneously. This means that a single server instance can support apps compiled with different runtime releases.
Each release of MATLAB Web App Server is designed to support a range of six MATLAB Runtime versions. This range starts from the MATLAB Runtime version tied to the current release of MATLAB Web App Server and extends to the previous five releases. However, it will not work with MATLAB Runtime releases prior to R2019b.
The full list of supported MATLAB Runtime versions per MATLAB Web App Server release can be found here:
To use a particular version of MATLAB Runtime with MATLAB Web App Server, the runtime must be installed in a location accessible to the server machine and configured during webapps-setup or using the webapps-runtime command. See also:
For the development version of MATLAB Web App Server (included with MATLAB Compiler):
The development version of MATLAB Web App Server only supports a single runtime release. This means that the development version of MATLAB Web App Server can only run apps compiled using the same release as the release of MATLAB Web App Server you have installed.
Note that if you do not have the correct runtime for a specific app configured on your server, you will see a "Required Runtime Unavailable" error in the Diagnostics tab.
