HeroMate vs Firebase and Appwrite: the established alternatives
Firebase and Appwrite come up in a different conversation than Supabase and InsForge — less "which one was built agent-first" and more "which established backend do I trust with a real product." Both are mature, both now ship an MCP server, and both are legitimate answers. The differences that actually matter show up once an agent starts operating them, not in the feature checklist.
Firebase: the most mature option, now agent-reachable
Firebase ships an MCP server through firebase-tools, exposing Firestore, Auth, Storage, Cloud Functions, Remote Config, and more to a connected agent — genuinely well-integrated, and backed by over a decade of Google's production hardening. If you already have a Firebase project, connecting an agent to it is a real, low-friction option.
The catch is underneath the MCP layer, not in it. Firestore is a NoSQL document store, and that data model is harder for an AI agent to reason about correctly than typed relational tables — there's no schema to check a generated query against, so mistakes are easier to make and harder to catch. Pricing is pay-per-read/write, which means a runaway query an agent writes can turn into a genuinely surprising bill, not just a bug to fix. And backend logic beyond what Firestore's rules can express means writing your own Cloud Functions — no workflow/orchestration layer.
Real fit: you already run Firebase, want the most battle-tested option available, and are comfortable reviewing generated Firestore queries and security rules carefully.
