Question: I'm looking for a solution that provides instant deployment of applications with a hosted database and API options.

For a full-featured hosted database and API option, Supabase is a powerful open-source alternative to Firebase. It includes a Postgres database, user authentication, instant APIs, real-time subscriptions and storage, all in a secure and scalable environment. It supports frameworks like Next.js, Svelte and Flutter, and has templates for common use cases. Its pricing plan begins with a free tier and moves up to Pro, Team and Enterprise levels, so it's good for everything from small projects to bigger ones.

Another good option is ROQ, which is geared specifically for building multi-tenant, multi-role SaaS applications. It includes a managed Postgres database deployment, secure frontend DB queries, user authentication with social logins, and role-based access control. ROQ also integrates with Stripe for payments and subscriptions, and has AI-assisted data modeling. It's good for developers who want to quickly build and deploy secure, scalable SaaS applications with complex data models.

For a no-code option, AppAsap offers an AI-powered platform that generates CRUD APIs in under 5 minutes. It also includes a chat interface for requirements analysis, a database visualizer, an API playground and a frontend builder. With built-in security and integration with AWS elastic services, AppAsap is designed to scale and accommodate the needs of larger applications. Its pricing plan starts at $30/month and moves up to enterprise plans for unlimited scalability.
