The bottom line

The most opinionated real-time backend for TypeScript teams who want subscriptions, transactions, and scheduling out of the box with zero infrastructure.

Conversion Gems editorial verdict
Free tier; Pro from $25/dev/mo
Features8/10
8 - reactive DB, serverless functions, file storage, vector search, crons, and auth in one SDK is comprehensive; limited SQL/relational flexibility.
Value8/10
8 - generous free tier, competitive $25/dev/mo Pro plan, startup program; Business tier jumps sharply to $2,500/mo minimum.
Ease of use8/10
8 - excellent DX for TypeScript developers with CLI scaffolding and auto-typed queries; steeper curve for teams new to reactive/functional data patterns.
Ecosystem7/10
7 - strong React/Next.js integrations and active community; narrower than Firebase or Supabase; limited non-JS SDKs.
Support7/10
7 - email support on Pro, active Discord community, solid docs; dedicated support only at Business/Enterprise tier.

What it really is

Convex — reactive Backend-as-a-Service platform with a TypeScript-native real-time database.

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. The DB summary ('text-to-LLM AI platform') and audience ('marketing teams / visual effects') are completely wrong; this is squarely a developer backend tool. Pricing was also mislabeled as 'Custom/Paid' — Convex has a genuine free tier and a clear $25/dev/mo paid plan.

Why we rate it

Convex 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 catch

Deep 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 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
Friction report
Time to value
Fast: `npm create convex` scaffolds a full-stack project with live queries in under 5 minutes; no database provisioning needed.
Scale breakpoint
Per-seat costs compound quickly on larger engineering teams; function call overages and concurrent session limits can surprise teams at growth stage.
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.
