I'm sorry in advance, this is going to be incredibly negative. I'll sum it up to this: WTF?
What's the motivation to build and launch this? Simplify authentication (it won't)? Make it more secure (it won't)? Make it cheaper (it won't)?
Your terms (https://pixlab.io/terms) are ridiculous. You might be the first SaaS I see that has both a "business-critical" tier and a "no warranty" clause in their terms.
Your "GDPR compliant" terms are out of whack, actually, too. Has a lawyer reviewed this? It's written for end users with no mention of customers or data processing agreements. You don't even have a DPO.
I'm doubly shocked because this looks like a lot of work and care has been put into this; what you built is a prototype at best, yet you're basically screaming that this is an enterprise-ready product you're fully launching.
