Kinde vs Supabase — Pricing, Plans, and Verified Costs (2026)
Kinde and Supabase both start at $25/mo on their entry tier.
How pricing works
These two tools don't price the same way, so the headline numbers below aren't directly comparable until you plug in your own volume.
- Kinde (Unknown model) — Kinde bills on a fixed plan from $25/mo, so the listed price is what you pay regardless of volume.
- Supabase (Hybrid) — Supabase is hybrid: a fixed subscription from $25/mo plus metered usage on top (Database size / MAUs). Your real bill moves with volume, not seat count.
Per-minute, per-credit and per-token rates exclude any downstream model, speech or telephony costs unless the vendor states otherwise.
Australian authentication platform positioned as the value alternative to Clerk and Auth0 for founders who want auth + billing + feature flags in one dashboard. Distinctive for its extra-generous free tier (10,500 MAU + billing + feature flags included). Pro $25/mo. Popular with solo founders and small teams shipping SaaS quickly — the 'auth + adjacent tooling' bundle no other provider offers at this price point.
Open-source Firebase alternative, valued $10.5B (June 2026 Series F led by GIC). Positioned as the alternative to Firebase for developers who want Postgres, open-source, and self-hosting option. Distinctive for shipping fast across auth, storage, edge functions, and vector database in a single platform. Free tier includes real production Postgres; paid tiers scale with usage (databases, storage, edge function invocations). Popular with AI/agent builders needing a proper database.

What each is best for
Kinde is worth it if… Kinde is the auth-as-a-service alternative to Auth0 and Clerk for developers who want simpler pricing and multi-language SDKs — particularly if Clerk feels too React-focused. Free tier covers up to 10K MAUs; Pro adds SSO and higher limits; Scale for larger orgs; new Plus tier launched 2026 sits between.
Supabase is worth it if… developers building modern web apps that want open-source Postgres + auth + storage + realtime + edge functions in one bundle — the Firebase alternative for SQL-first teams. Free tier covers development; Pro adds daily backups and higher limits; Team adds SOC2 and more capacity; Enterprise custom.
Bottom line: Similar positioning, closer to a preference call than a strategic one.
