You have built a really great product that is easy to use. I've tested out the self-hosted option on render.com with neon postgres and the cloud version. Both are super easy to get up and running.
Now, it is no exaggeration to say that the most annoying part of adding a new integration is just navigating the API provider's portal to get the app outh creds.
I agree that getting approved to have an OAuth app is a major pain point (for some APIs). We help customers navigate this and would like to do more in the future (partner with API providers, offer sandbox accounts without approval, and even manage the approvals for customers when possible).
