Question: Can you recommend a platform that allows me to build production apps with a Postgres database and real-time data synchronization?

If you want a foundation for building production apps with a Postgres database and real-time data synchronization, Supabase is a great option. Supabase is an open-source Firebase alternative that lets developers build production apps with a Postgres database, user authentication, instant APIs, real-time subscriptions, storage, and vector embeddings. It supports frameworks like Next.js, Svelte and Flutter. Supabase also comes with a data management dashboard, a table editor and an in-built SQL editor, so it's a good option for building and managing databases and real-time data applications.

Another contender is Xata, a serverless data platform built on PostgreSQL. Xata lets developers fit into their existing workflow with features like serverless Postgres, zero-downtime schema migrations, file storage, branching, full-text search with Elasticsearch, AI integration and elastic scaling. Xata supports a variety of frameworks and tools, so developers can use what they're already familiar with. Its free tier is generous, with high availability, 15 GB data storage and 250 AI queries per month, so it's a good starting point for growing projects.

If you want a full data and API layer, check out ROQ. ROQ is geared for building multi-tenant, multi-role SaaS applications with secure database queries, user authentication and role-based access control. It also offers managed Postgres database deployment, secure frontend DB queries and AI-assisted data modeling, so it's a good option for developers who want to build secure and scalable apps efficiently.
