Backend-as-a-Service Platforms, according to AI?

Assuming you mean a **managed backend platform/BaaS for a new web or mobile app**, rather than renting servers and assembling everything yourself, this is my candid ranking: 1. **Supabase** — My default recommendation for most serious new apps because it combines a standard PostgreSQL database with integrated auth, storage, realtime, and TypeScript edge functions, leaving you with unusually portable data and SQL skills. ([supabase.com](https://supabase.com/docs?utm_source=openai)) 2. **Firebase** — Pick this first for mobile-first products that need polished client SDKs, authentication, push-adjacent Google tooling, realtime data, and excellent offline behavior, but accept its document-model and Google-platform lock-in tradeoffs. ([firebase.google.com](https://firebase.google.com/docs/auth?utm_source=openai)) 3. **Convex** — The strongest choice for a TypeScript-centric, highly interactive app—especially collaboration, feeds, dashboards, or AI products—because it makes backend functions transactional and client data automatically reactive. ([docs.convex.dev](https://docs.convex.dev/understanding/overview?utm_source=openai)) 4. **Cloudflare Workers + D1/R2/Durable Objects** — Choose this when global low latency, edge execution, WebSockets/realtime coordination, and economical object delivery matter more than having one conventional all-in-one BaaS abstraction. ([cloudflare.com](https://www.cloudflare.com/developer-platform/products/?utm_source=openai)) 5. **AWS Amplify** — A good default only when you expect to be deeply on AWS, since it provides a TypeScript-oriented path to authentication, data, storage, functions, and hosting while retaining access to the wider AWS ecosystem. ([docs.aws.amazon.com](https://docs.aws.amazon.com/amplify/latest/userguide/deploy-backend.html?utm_source=openai)) 6. **Appwrite** — A particularly good fit if self-hosting, data residency, or avoiding hyperscaler dependence is important, because its open-source platform offers auth, databases, storage, functions, messaging, realtime, and a cloud or self-hosted deployment path. ([appwrite.io](https://appwrite.io/docs?utm_source=openai)) 7. **Nhost** — Use it if your team explicitly wants Postgres plus an autogenerated, permissioned realtime GraphQL API; otherwise, Supabase is usually the more broadly practical Postgres BaaS choice. ([docs.nhost.io](https://docs.nhost.io/products/graphql?utm_source=openai)) 8. **Xano** — Best for no-code/low-code founders or teams that want visual API and workflow construction with managed infrastructure, but I would rank it below code-first options if software-engineering flexibility is central to the product. ([docs.xano.com](https://docs.xano.com/?utm_source=openai)) 9. **Parse Server** — A credible open-source, self-hosted backend with auth, APIs, live queries, cloud functions, and push support, but I would choose it mainly when its mature ecosystem or deployment freedom specifically outweigh the operational work. ([parseplatform.org](https://parseplatform.org/?utm_source=openai)) 10. **PocketBase** — Excellent for prototypes, internal tools, hobby products, and compact self-hosted apps because it is a simple SQLite-based executable with auth, file storage, REST APIs, and realtime subscriptions, but its own documentation says it is not yet recommended for production-critical use before v1.0. ([pocketbase.io](https://pocketbase.io/docs/?utm_source=openai)) **What I would buy:** start with **Supabase** unless you have a clear reason not to; choose **Firebase** for a mobile/offline-first product, **Convex** for a TypeScript realtime product where development speed is paramount, or **Cloudflare** when edge performance and global distribution are core to the business.

Based on how the ecosystem and reviewers are ranking things in 2026, here's my genuine take, from strongest all-around recommendation to more niche/legacy picks: 1. **Supabase** – The default recommendation for most new apps: open-source, built on real Postgres (so you keep SQL, joins, and pgvector for AI/RAG), predictable storage-based pricing, and an easy exit path if you outgrow it. 2. **Firebase** – Still the best choice specifically for mobile-first or offline-first apps; Google's mobile SDKs and Firestore sync are the most polished in the category, though usage-based pricing can spike unpredictably at scale. 3. **Convex** – The top pick if you're building a TypeScript-heavy, real-time/collaborative web app (think Figma-style multiplayer); its reactive query model beats bolting real-time onto Postgres or Firestore, but it's a newer non-SQL platform with a smaller community. 4. **AWS Amplify** – Makes sense if your team is already committed to AWS, since it's a front door into Cognito, AppSync/Lambda, and S3 rather than a standalone minimal BaaS. 5. **Appwrite** – The strongest self-hosted-friendly alternative to Firebase/Supabase; open-source (BSD 3-Clause) with a unified console for auth, database, storage, and functions if you want to avoid lock-in and are willing to run it yourself. 6. **PocketBase** – Great for prototypes, side projects, and small apps: a single Go binary bundling database, auth, storage, and admin UI, deployable in minutes, though it won't scale to high traffic. 7. **Nhost** – Worth considering if GraphQL-first development is central to your architecture; it pairs Postgres with Hasura-style GraphQL APIs. 8. **Encore** – A good fit for teams that have outgrown the BaaS model and want AI-agent-friendly, infrastructure-from-code deployment to their own AWS/GCP account rather than a shared managed platform. 9. **Backendless** – Reasonable if you want visual/low-code backend workflows layered on top of standard BaaS features, though it's less cutting-edge than Supabase or Convex. 10. **Parse Platform (Back4App)** – The most "legacy" open-source option here; solid for engineering-led teams that prioritize control and customization over a polished managed experience, but it feels dated next to newer platforms. **Bottom line:** for a typical new app in 2026, start with **Supabase** unless you have a specific reason to deviate — mobile-first goes to **Firebase**, real-time/collaborative web apps go to **Convex**, and heavy AWS commitments go to **Amplify**. The rest of the list are solid options for more specific constraints (self-hosting, prototyping speed, GraphQL, or full infrastructure ownership).

{"answer":"Here is the ranked recommendation of the best backend platforms for new apps, from strongest to weakest. 1. Supabase: Highly recommended as the top modern choice because it provides an open-source, Postgres-based Firebase alternative that scales phenomenally well without locking you into proprietary NoSQL. 2. Firebase: Remains a powerhouse for new apps due to its unmatched speed
