Convex

Convex positions itself as a reactive backend platform that keeps applications and AI agents in sync with live data. Rather than assembling a database, serverless functions, and separate sync tooling, developers get one integrated system built around TypeScript.

The core feature set includes real-time data sync, authentication with over 80 OAuth integrations, an AI gateway for calling major models from one API, and modular TypeScript components. Workflows, search, and file storage are included, and the platform supports AI-assisted code generation plus open-source local development.

It is aimed at developers and startups building real-time web applications, collaborative products, and agent-driven experiences. Teams evaluating Firebase or Supabase alternatives are a natural audience, as are open-source projects needing a managed or self-hosted backend.

New users can start from documentation, framework-specific guides, and templates, then use the community Discord and Stack blog for support. Comparing it against existing backends before migrating is advisable, and self-hosting is available for those who need control over infrastructure.

Overall, Convex reduces backend glue work for TypeScript teams that want reactivity and AI integration built in.
