What is Convex?
Convex is the open-source, reactive database platform designed for web and mobile developers. It provides a complete, TypeScript-native backend to help you build, launch, and scale modern applications with remarkable speed and reliability. By handling real-time data synchronization automatically, Convex lets you focus on creating features, not managing state.
Key Features
⚡ Automatic Real-Time Reactivity Convex is architected around a reactive core. It automatically tracks all data dependencies for every query, so whenever underlying data changes, your UI updates instantly without any manual polling, cache invalidation, or state management boilerplate. This eliminates entire classes of complexity, ensuring your app is always in sync.
💻 Unified TypeScript Backend Define your entire backend—from database schemas and queries to mutations and cron jobs—in pure TypeScript. This provides end-to-end type safety from your database to your UI, enabling superior autocompletion, static analysis, and developer confidence. Because your backend is just code, it integrates seamlessly with AI code generation tools.
🔐 Built-in, Full-Stack Authentication Simplify your stack with Convex Auth, which integrates a user table directly into your backend. You can reference user data in any function without calling an external service. It supports modern login methods out-of-the-box, including Magic Links, OTP emails, password-based sign-in, and over 80 OAuth providers through its Auth.js integration.
🧩 Extensible Backend with Components Instantly add powerful, pre-built features to your application with Convex Components. These are sandboxed, modular TypeScript packages for common needs like real-time user presence tracking, AI agents with vector search, transactional email (Resend), and durable background jobs. This allows you to add sophisticated functionality in minutes, not days.
Use Cases
Build Real-Time Collaborative Tools: Create applications like shared whiteboards, project management dashboards, or collaborative document editors. When one user makes a change, Convex's reactivity ensures every other connected client sees the update immediately, creating a seamless, interactive experience.
Develop AI-Powered Chat Applications: Leverage Convex Components like
AI AgentandPersistent Text Streamingto build intelligent chatbots or customer support tools. You can stream responses from an LLM to the user in real-time while efficiently storing the conversation history, complete with built-in memory and vector search for context.Rapidly Prototype and Launch MVPs: Go from idea to a deployed full-stack application with incredible speed. Use the
npm create convexcommand to start, let AI tools like Convex Chef generate your initial TypeScript backend, and add authentication and other features with a few lines of code.
Why Choose Convex?
Convex is more than just a database; it’s a cohesive backend platform that solves fundamental challenges in modern application development.
Eliminate State Management Complexity: Traditional development requires complex logic for data fetching, caching, and keeping the UI synchronized with the backend. Convex’s ubiquitous reactivity handles this automatically, freeing you to focus on your product's core logic.
Achieve End-to-End Type Safety: By using TypeScript for your entire stack, you remove the friction and potential for error that comes from context-switching between languages like SQL, JavaScript, and backend frameworks. Your database schema, queries, and client code are all part of a single, type-safe system.
Build Without Fear of Vendor Lock-In: With a fully open-source backend, you have the freedom and confidence to build on Convex for the long term. You can develop locally for maximum speed and have the option to self-host for compliance or specific infrastructure needs.
Accelerate Development with an Integrated Ecosystem: Instead of stitching together multiple third-party services for auth, background jobs, and file storage, you can use Convex Components. These are designed to work seamlessly within the Convex environment, providing a clean, well-documented, and integrated developer experience.
Conclusion
Convex provides a powerful, integrated, and developer-friendly platform for building the next generation of real-time and AI-driven applications. By unifying your backend in TypeScript and making reactivity the default, it empowers you to build more resilient, interactive, and feature-rich products faster than ever before.
