Authentication & Identity shortlist: Customers (B2C / B2B SaaS)

Find the right auth provider based on who you're authenticating, what compliance requirements apply, and what your team can realistically operate. A developer-first startup self-hosting Supabase Auth has different needs than an enterprise deploying SSO across 10,000 employees with SOC 2 requirements. Pricing models differ significantly too—per-MAU versus per-seat versus flat-rate can change your total cost by 10x at scale. These filters help you skip the obvious mismatches.

How shortlists work: We match products against your constraints using pricing tiers, team fit, and workload alignment. Verify each against your specific requirements before committing.
