Yes, it will save me _weeks_ of work. But, I think that there are a few fundamental issues at play here. 1. I think every project has different requirements, e.g. what if I want phone auth or single sign-on using email. Once you add all those features, your product is likely to become complex like Firebase Auth or Auth0 where understanding third-party APIs is almost equivalent to writing your own system (especially since open-source ecosystem already has key components available). You might argue that the solutions have client libraries to make things super simple, but in real world applications, plug-and-play rarely works to perfection. 2. Projects that are just starting out can't really afford third-party solutions. Once they can, they can also afford to build their own. 3. Solutions to these things already exists, just not in one place. Netlify has a solution for Forms and templates (I think). For Auth, we have Okta, Auth0 and Firebase. For emails, I think Amazon SNS (not sure).
