The bundle size that can be uploaded is limited to 1 GB for the Free and Starter plans, and up to 8 GB for the Basic, Standard and Professional plans.
For the latter plans, note that the
rsconnect package has a default bundle size limit of 1 GB, independent of your shinyapps.io plan limit. If you plan to deploy application bundles larger than 1 GB in size, you can override the
rsconnect default by setting this option first:
options(rsconnect.max.bundle.size=...) where the value is in bytes. Do not set the maximum size larger than the limit for your shinyapps.io plan, or application deployments will fail.
