Convex ranks #4 in Backend-as-a-Service & Realtime AI search.

Convex is a US-based Backend-as-a-Service and reactive database platform founded in 2021 by former Dropbox engineers. It provides a fully managed, serverless backend where database schemas, queries, mutations, and scheduled jobs are expressed as TypeScript code living alongside frontend code. Convex's core architectural differentiator is automatic, server-driven reactivity: client queries subscribe to results and update in real time without WebSockets, state managers, or cache invalidation logic. The platform includes built-in authentication, file storage, text and vector search, and a growing npm-based component ecosystem. The open-source backend (Rust, Apache-2.0) supports self-hosting. Convex is SOC 2 Type II, HIPAA, and GDPR compliant, and has raised approximately $50M from Andreessen Horowitz and Spark Capital.

Convex is a TypeScript-native, reactive Backend-as-a-Service platform that unifies a serverless document database, real-time query subscriptions, background functions, authentication, file storage, and vector search under a single, fully managed cloud service. Developers define their entire backend—schemas, queries, mutations, crons, and auth—as typed TypeScript functions co-located with frontend code, with the platform handling synchronization, caching, and scaling automatically.
