Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Auth0
- Free tier limited to 25,000 monthly active users, requiring upgrade for growth beyond that
- Advanced features like MFA and RBAC only available on paid Essentials tier and above
- Ownership by Okta introduces risk that independent product roadmap may change
Lovable
- Credit-metered rather than unlimited: Free plan gets 5 build credits/day capped at 30/month, plus 20 cloud-hosting credits/month and 4 AI-feature credits/month
- Credits expire: monthly plan credits expire after 2 months unused, annual-plan credits expire 1 month after the annual period ends, and all credits are non-refundable
- Not open source; only the legacy precursor CLI gpt-engineer is open source (MIT), and that repo was archived read-only on 2026-04-22
- Hosting is free only for smaller apps; significant traffic or size draws additional charges from the credit balance
