Usage drives both bills; effort drives the breakeven.

Migration verdict

Stay on Better 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

Better Auth$0.00/mo
Note$0.00
  • You own security patching, session hygiene and edge cases — the $0 price is paid in responsibility
  • Prebuilt UI is thinner than Clerk's; budget time for auth screens

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

The math, line by line

Current bill (Better Auth)$0.00/mo
Best alternative bill (Clerk)$0.00/mo
Monthly savings$0.00/mo
Migration effort (18h × $50/h — both sliders, our-estimate defaults)$900.00
Year one nets−$900.00

Bills computed by the same engine and verified data as the auth provider selector; switching-cost inputs are yours to set — we only default them.
