Both Supabase Auth and Stytch offer a free tier, so entry-level cost is not a differentiating factor. Compare the feature and usage limits of each free plan to see which gives you more headroom before a paid upgrade is needed.
Supabase Auth scores higher on Free Tier — 98/100 versus 78/100 for Stytch. If free tier is your primary decision criterion, Supabase Auth is the stronger choice in this head-to-head.
Switching between auth providers tools is generally possible but involves migration effort: exporting your data or configuration from Supabase Auth, re-importing or reconfiguring in Stytch, and updating any API integrations or environment variables in your codebase. The effort scales with how deeply embedded the tool is in your stack. Test Stytch on a non-production project first before migrating.
Supabase Auth (85/100) is the better fit for teams who prioritise free tier — its strongest dimension — and who want a free entry point. Stytch (85/100) is the better fit for teams who prioritise security and want a free entry point. If both dimensions matter equally, the overall score winner (either tool) is the safer default choice.
