BedrockvsSupastarter

Bedrock ($249) and Supastarter ($299) are both enterprise-grade Next.js SaaS boilerplates with multi-tenancy, an admin panel, Stripe billing, and production-ready architecture — but they make fundamentally different choices about the authentication layer. Bedrock uses Clerk, a hosted identity platform that handles user management, session tokens, MFA, and organization management via an external service. Supastarter uses Supabase Auth, which is self-contained in your database. This auth choice cascades into every part of the stack.

Clerk's managed auth is a significant operational advantage. Sign-in flows, password resets, MFA enrollment, user impersonation, and the user management dashboard are fully handled by Clerk — no auth code in your codebase means no auth security vulnerabilities to maintain. Clerk's organization primitive maps directly to SaaS team management: organizations contain members, members have roles, and Clerk's JWT claims carry org context into every request. Bedrock builds its multi-tenancy on top of Clerk's organizations, which is elegant and reduces custom code. The tradeoff is Clerk pricing: the free tier covers 10,000 monthly active users, but at scale you'll pay per user. For high-volume consumer SaaS products, this can become meaningful.

Supastarter's Supabase Auth is part of your Supabase project — it's PostgreSQL under the hood with row-level security policies enforcing data access. There's no third-party auth vendor billing, which matters at scale. The Supabase ecosystem also gives you a tight integration between auth, database, storage, and real-time subscriptions — these systems share the same auth context natively. Supastarter also includes i18n (internationalization) out of the box, a feature Bedrock lacks, which is significant for products targeting non-English markets. Supastarter's $299 price includes a monorepo structure, testing setup, and a more polished admin dashboard.

Choose Bedrock if you want Clerk's best-in-class managed auth with user impersonation, a familiar organization model, and are building a product where auth complexity (SSO, SAML, fine-grained organization permissions) could grow over time. Choose Supastarter if you want the full Supabase ecosystem with no per-user auth billing, need internationalization built in, and prefer all your backend services in one platform rather than orchestrating multiple vendors.
