Features Overview
Convex's reactive data model is its killer feature. Write a query, and any component using that query automatically re-renders when the underlying data changes — no subscriptions, no WebSocket management, no polling. The TypeScript integration is genuine end-to-end: schema types flow from database to server functions to client. Built-in ACID transactions, file storage, and authentication integrations (Clerk, Auth0).

| Plan | Price | Key Features |
|---|---|---|
| Free | $0 | 1GB database, 1M function calls/mo |
| Starter | $25/mo | 10GB database, 5M calls/mo, support |
| Professional | $100/mo | 50GB, 25M calls/mo, priority support |
Who Should Choose Convex?
- Teams building collaborative tools (docs, chat, whiteboards)
- TypeScript developers who want end-to-end type safety
- Projects where real-time is a core feature, not an add-on
- Developers who want the simplest possible real-time model

Which do you use?
Who Should Choose What?
→ Choose Supabase if:
You want a proven, industry-standard backend with full Postgres power. Supabase is the safe bet for most projects — SQL flexibility, massive ecosystem, self-hosting option, and a clear path when you outgrow BaaS.
→ Choose Convex if:
You're building a real-time-heavy app (collaborative tool, live dashboard, chat) and want automatic reactivity without WebSocket boilerplate. Convex's TypeScript-first approach and automatic real-time updates are genuinely delightful to work with.
→ Consider neither if:
You need a managed MySQL database. PlanetScale offers serverless MySQL with branching workflows. Or if you want Firebase-style mobile BaaS, Firebase or Appwrite might be better fits.

Frequently Asked Questions
Editor's Take
I use Supabase for most of my projects — the Postgres foundation means I can always fall back to raw SQL when the abstraction layer isn't enough. But I recently built a collaborative whiteboard on Convex and the DX was genuinely magical. Data just... updates. Everywhere. No subscriptions, no state management headaches. If real-time is your core feature, try Convex. For everything else, Supabase is the safe pick.
