Overview
Convex is a backend platform that provides building blocks for AI agents and full-stack applications. It lets developers express every part of their backend—from database schemas to queries, auth to APIs—in pure TypeScript. The platform keeps your frontend, backend code, and database state always in sync in real time, eliminating the need for state managers, cache invalidation policies, or websockets. Convex also offers built-in tools like cron jobs, backend AI workflows, and a growing ecosystem of components that can be installed with a simple npm i .
Application scenarios
Real-time todo apps
Build reactive todo lists where data updates instantly as you change code or database state.
AI workflow orchestration
Kick off backend AI workflows with built-in cron jobs and internal mutations.
Full-stack TypeScript projects
Develop complete applications where backend code lives alongside frontend code, with full typechecking and autocompletion.
Authentication systems
Leverage built-in auth to handle user login and permissions without external services.
Component-based backend development
Install reusable backend components from Convex's ecosystem to solve common needs like categorization or scheduling.
Database-driven applications
Define schemas with typed fields (strings, booleans, optional values) and query data efficiently using indexes.
Core features
Everything is code
Express your entire backend—database schemas, queries, mutations, auth, and APIs—in pure TypeScript, with AI-generated code that achieves exceptional accuracy.
Real-time sync
Convex libraries guarantee your app always reflects changes to frontend code, backend code, and database state in real time, without manual state management.
Built-in cron jobs
Create scheduled tasks that run at intervals (e.g., every 5 seconds) using Convex's cron job system.
Backend AI workflows
Kick off AI-powered processes directly from your backend code.
Built-in authentication
Leverage Convex's built-in auth system for user management and secure access.
Component ecosystem
Install reusable backend components with a simple `npm i` command to solve common needs like categorization.
TypeScript-first development
Backend code is fully typechecked and autocompleted, with AI generation that produces accurate results.
Schema definition
Define typed database tables with fields like strings, booleans, and optional values, plus indexes for efficient querying.
Target users
Convex is designed for full-stack developers and AI engineers building modern web applications. It's particularly useful for teams who want to build backend infrastructure quickly without managing servers, state management, or WebSocket connections. TypeScript developers will benefit most from the deep integration and autocompletion features.
How to use
To get started, run npm create convex in your terminal. This scaffolds a new project with the Convex backend. You then define your database schema in convex/schema.ts , write queries and mutations in convex/todos.ts , and connect your frontend using the useQuery hook from the convex/react package. The platform automatically syncs changes in real time as you modify code or database state.
Effect review
Convex delivers on its promise of making backend development as simple as writing frontend code. The real-time sync feature eliminates the complexity of state management and WebSocket handling, which are common pain points in modern web development. The AI code generation capability, while not detailed in its accuracy metrics, suggests a significant productivity boost for TypeScript developers. The component ecosystem and built-in cron jobs provide practical solutions for common backend tasks without requiring additional services. Overall, Convex offers a compelling, developer-friendly approach to building full-stack applications with minimal boilerplate.
