This is really cool. It offers a simple way to manage and monetize APIs with a excellent foundation.
What I like:
1. It is really simple to use. The onboarding is spot on. In a matter of minutes, you get an (client) API Portal.
2. Multiple ways to monetize APIs.
3. Ready to use (client) API Portal.
What I don't like:
1. You don't really get a "Custom branded" (client) API Portal it's more like a co-branded experience. On The Client API Portal you have "Powered by Blobr" and on the client e-mails the footer is all Blobr.
2. I can't really use it right now, because I can't use Stripe.
3. You can't really (fully) edit and API once it was added. Similar thing for products.
In the end, it looks like a great product and a good deal. I hope Blobr will become a powerful product in the future.
