Convex uses per-seat pricing — costs grow with team size. Think something is wrong?
What Convex excels at
- Reactive queries: Convex functions subscribe to data — UI updates automatically when data changes without polling.
- TypeScript-native: fully typed queries, mutations, and actions — no SQL or ORM required.
- Built-in scheduling and cron: run background jobs and recurring tasks without a separate queue.
- Transactional mutations: all writes are fully ACID at the function level.
- Real-time by default: WebSocket subscriptions are a first-class primitive, not an add-on.
How Convex pricing works in 2026
Convex Professional uses a per-seat pricing model: $25/developer/month, regardless of data volume or query count (within plan limits). This is fundamentally different from storage-based providers like Neon or Supabase — your cost scales with team size, not traffic or data.
The Professional plan includes 50 GB database storage, 50 GB DB I/O, 50 GB egress, and 250M function calls per month. Overage is $0.20/GB for storage and I/O, and $0.12/GB for egress. Function call overage is $2/million.
Convex is not Postgres
Convex uses its own document-oriented data model, not Postgres. There is no SQL, no schema migrations with ALTER TABLE, and no ORM compatibility. Queries and mutations are written as TypeScript functions that run inside Convex's transactional runtime. This is a paradigm shift — not a drop-in database replacement.
The trade-off is that Convex's model enables reactive queries by default: UI components subscribe to Convex queries and update automatically when the underlying data changes. Building real-time features requires no additional infrastructure — no WebSocket servers, no polling, no pub/sub setup.
Convex pricing examples
Solo developer, small app: 1 developer × $25 + minimal usage within included limits = $25/month.
3-person startup: 3 developers × $25 + minimal usage = $75/month.
10-person team with high storage (200 GB): 10 × $25 + 150 GB storage overage × $0.20 = $280/month.
When Convex makes sense
Convex is a strong choice for real-time collaborative apps, live dashboards, multiplayer features, and apps where the UI needs to react to data changes instantly. The reactive query model eliminates significant infrastructure work for these use cases.
Convex is a poor choice for apps that need SQL, complex joins, existing ORM codebases, or PostgreSQL-specific features like Row Level Security, PostGIS, or pg_vector. Migrating a Postgres app to Convex requires a full data model rewrite.
How this calculator works
The calculator uses your team size to compute the seat cost, then adds storage overage (above 50 GB) and egress overage (above 50 GB). DB I/O is estimated at 0.05 GB per active compute hour — a rough heuristic for typical SaaS query patterns. Actual I/O depends heavily on your query structure. Function call costs are not modeled.
Frequently asked questions
How much does Convex Professional cost per month?
$25/developer/month. A solo developer pays $25/month; a 5-person team pays $125/month. Usage overage is rare within Professional plan limits for most early-stage apps.
Does Convex have a free plan?
Yes. The Starter plan is free and includes a single project with generous limits — suitable for side projects and prototyping. The Professional plan adds team collaboration, higher limits, and production-grade features.
Convex vs Supabase — which should I use?
Use Supabase if you need SQL, Postgres compatibility, RLS, or are building with MakerKit (which has first-class Supabase integration). Use Convex if real-time reactivity is a core product requirement and you are willing to build around Convex's document model and TypeScript-native query API. They are not interchangeable.
Can I use Convex with Next.js?
Yes. Convex has a Next.js integration with React hooks for reactive queries. It works with App Router and Server Components, though reactive subscriptions are client-side. Server-side rendering fetches a snapshot; live updates happen after hydration.
Want a fully pre-integrated stack?
MakerKit uses Supabase by default — auth, database, storage, and real-time all pre-configured. No glue code, no per-seat pricing.
