Migration verdict

Stay on Supabase Auth

The best alternative doesn't even save money at your usage ($0.00 vs $0.00/mo) — migrating costs time AND money.

You today

Supabase Auth$0.00/mo

Fits the free tier at your usage.

  • Makes most sense when Supabase is already your backend — as standalone auth you're buying a platform
  • Organizations/teams model is DIY compared to Clerk/WorkOS

Best alternative

Clerk$0.00/mo

Fits the free tier at your usage.

  • Cost scales with users: 100K MRU ≈ $25 + 50K×$0.02 = $1,025/mo — model your growth before committing
  • B2B organizations add-on is $100/mo on top of Pro
