Convex

Convex is a reactive Backend-as-a-Service platform for developers, with TypeScript-native real-time data storage.

Our take: Convex is a full-featured BaaS that gives developers a reactive, transactional database, serverless functions, file storage, vector search, cron jobs, and auth — all written in TypeScript with end-to-end type safety.

What it really isConvex — reactive Backend-as-a-Service platform with a TypeScript-native real-time database.
Our takeConvex is a full-featured BaaS that gives developers a reactive, transactional database, serverless functions, file storage, vector search, cron jobs, and auth — all written in TypeScript with end-to-end type safety.
Convex is a developer backend tool. Convex has a free tier and a clear $25/dev/mo paid plan.
Why we rate itConvex collapses backend complexity — database, caching, subscriptions, jobs, and storage — into a single TypeScript SDK.
The reactivity model is genuinely differentiated: queries are functions that re-run server-side when dependencies change, meaning live UIs are free.
The catchDeep lock-in to the Convex data model and function runtime.
Migrating away requires rewriting backend logic; there is no SQL escape hatch. The opinionated TypeScript-only stack is a dealbreaker for non-JS teams.

Best / not good for

Best for
  • TypeScript teams building real-time collaborative or multiplayer apps
  • Startups wanting a batteries-included backend without DevOps overhead
  • React/Next.js projects that need live data subscriptions without WebSocket wiring
Not good for
  • Teams using Python, Go, or non-JS backend languages
  • Apps that need direct SQL or complex relational query patterns
  • Enterprise teams with strict data residency or bring-your-own-infrastructure requirements
Trade-offs

Friction report

Trade-offs to know before signing up.

  1. Time to value
    Fast: `npm create convex` scaffolds a full-stack project with live queries in under 5 minutes; no database provisioning needed.
  2. Scale breakpoint
    Per-seat costs compound quickly on larger engineering teams; function call overages and concurrent session limits can surprise teams at growth stage.
  3. Walled garden
    High: data and logic are tightly coupled to Convex's runtime and query model; exporting data is possible but re-platforming is costly.
Still a fit?
If none of these block you, start on the free plan.
