How does this compare to Pomerium or other open source IAPs?

Another contender in this area would be:

https://github.com/oauth2-proxy/oauth2-proxy

I've used that to gate-access to internal things behind gsuite domains, and it supports authentication against github and other providers too.

Also https://github.com/Widen/cloudfront-auth if you're OK fronting your service with CloudFront and Lambda@Edge for auth.
