My app is basically a redirect service that we point old sub-domains to for redirect to another location. That means I’ll be pointing many domains at my app. Is there a limit to the number of custom domains or certificates an app can have?
there isn’t a limit of custom domains! we have a few customers with the same use case, it should work just fine.
FYI if you’re backfilling a large amount of subdomains, the one case you might hit is a rate limit for certificates from Let’s Encrypt. They have a limit of 50 certificates per domain per week.
