The Verdict
SuperTokens is built for saas developers and startups, with a focus on email-password and social-login. Sync.com targets privacy conscious users and healthcare professionals and leads with end-to-end-encryption and file-sharing.
On pricing, SuperTokens is the clear winner for budget-conscious users — starting at $0.02/mo compared to $6/mo for Sync.com. That $5.98/mo difference adds up quickly for growing teams.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
Feature-wise, SuperTokens offers broader built-in capabilities (7 features vs 6), while Sync.com takes a more focused approach — which can mean a simpler, faster onboarding experience.
