The Verdict
Firebase is built for mobile developers and startups, with a focus on firestore and authentication. SuperTokens targets saas developers and startups and leads with email-password and social-login.
Both tools come in at similar price points ($0/mo for Firebase, $0.02/mo for SuperTokens), so pricing won't make the decision for you.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
Both tools are a solid fit for startups — in those cases, the decision often comes down to workflow style and how your team prefers to organize work.
This is a genuinely close comparison. If you can, sign up for both free trials (where available) and run a one-week test with your actual team tasks before deciding.
