Every one of the various customers ech one of us may have features its own set of providers. Some may come more often than not (Okta, Splunk, Azure…) and some less (Duo, Loki, Scaleway, whatever…)
For our own projects we sat on those below.
Cloudflare is like a global startup program. Well, when it comes to the hosting costs. You still have to find early employees and find a way to offer them compensation of course.
But still, they've got so many free services, choosing them is a must.
Pages is free static website hosting behind a worldwide CDN.Workers is free API with Fetch and cache support to get your other cloud
vendors resources if not present.For a very fair pricing you have as many domains and mailboxes you want under a true email hosting, so aliases catchalls and whatnot.
It's not free it's just paying for what you cost them and a little more.
They have the most comprehensive authn / authz platform so far. Including an hosted login form.
They have docs, they support IdP / ID tokens to integrate to portals if you do an SaaS etc.
Their only drawback so far is they've been acquired by Okta.
