Magic.link is venture funded with steep pricing per user. This makes sense for their enterprise target market, but for a hobby project I can't remotely afford it. They keep a record for you of your users, in my product that's your own responsibility (which imo is a good thing).
tldr: What I'm building is simpler, and much more affordable, but not enterprise-feature complete.
I think it’s awesome you’re building an alternative with a different feature set, I’m really curious to hear your take on pricing.
Not offering SAML/SSO/OIDC etc simplifies the problem a lot allowing me to offer it cheaply. The largest cost is sending the e-mails reliably, for which I am wrapping Amazon SES.
That being said, I can imagine there are people who would prefer a per sign in model, it’s just a level of granularity I don’t care for.
Good luck!
