Convex vs Supabase — Pricing, Plans, and Verified Costs (2026)
Convex 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.
- Convex (Unknown model) — Convex 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.
Reactive backend platform positioned as the alternative to Firebase for TypeScript developers who want end-to-end type safety + real-time subscriptions without configuring WebSockets. Distinctive per-developer pricing ($25/dev/mo Professional) instead of usage-based — predictable bills regardless of data volume or query count. Free tier is generous for solo projects. Popular with venture-backed startups building interactive AI/collaboration apps.
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
Convex is worth it if… Convex is the reactive backend-as-a-service for developers who want real-time database + serverless functions + file storage — all with TypeScript type safety end-to-end. Free tier covers development and small production apps; Starter (free with usage-based overages) removes hard caps; Professional adds team features.
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.
