Convex

Convex is a full-stack cloud backend platform designed to replace your database, server functions, authentication, and API layer with a unified TypeScript-first solution. It provides real-time reactivity out of the box — whenever data changes, all active client subscriptions update automatically without requiring websockets, state managers, or cache invalidation logic. The backend is open source and can be self-hosted, while the managed cloud offering handles scaling, backups, and infrastructure automatically. AI tools generate high-quality Convex code because everything is expressed in pure TypeScript.

Key Features:

• Real-time database — Convex tracks query dependencies and automatically pushes updates to clients whenever underlying data changes, keeping your app always in sync.
• TypeScript-first backend — Define database schemas, queries, mutations, and actions entirely in TypeScript, with full type safety and autocomplete from schema to client.
• Built-in authentication — Supports 80+ OAuth integrations and works seamlessly with providers like Clerk, Auth0, and others.
• Cron jobs & scheduled functions — Schedule recurring backend tasks or one-off jobs directly in code using cronJobs() without external infrastructure.
• Actions for external services — Call third-party APIs like OpenAI, Stripe, or Anthropic from Convex actions, which integrate cleanly with transactional queries and mutations.
• File storage — Store and serve files with built-in file storage, including bandwidth and storage quotas on each plan.
• Vector search — Run semantic/vector search queries natively within the Convex database for AI-powered features.
• Text search — Full-text search is built in, requiring no external search service.
• Modular components — Install independent TypeScript backend building blocks via npm i to solve common backend needs like rate limiting, presence, and more.
• Open source & self-hostable — The Convex backend is open source and can be run locally or on your own infrastructure with Docker and Postgres.
• AI coding support — LLMs generate accurate Convex code because the entire backend is TypeScript; includes Convex Chef for AI-powered app generation.
• Framework integrations — Quickstart guides for React, Next.js, Remix, Vue, Svelte, React Native, TanStack Start, Python, and Rust.
• SOC 2, HIPAA, and GDPR compliant — Enterprise-grade security and compliance built into the managed cloud platform.

To get started, run npm create convex in your project directory, follow the quickstart for your framework, and deploy your first backend function in minutes.
