What Backend Features Does Singlebase Combine?
Updated
Singlebase is an AI-native backend platform that bundles four core backend capabilities into one service: a document database, a vector database, authentication, and storage — plus built-in AI services on top. It's positioned as a Firebase alternative, so the practical question is whether those four features cover what your app actually needs. If you're building an app that stores structured records, runs similarity search, manages user sign-in, and handles file uploads, Singlebase is designed to cover all of that from one platform rather than stitching together separate vendors.
The Four Core Backend Features
Document Database
A document database stores data as flexible, JSON-like records instead of rigid table rows. This suits application data that changes shape over time — user profiles, posts, orders, settings — without requiring schema migrations for every new field. If your app's data model is still evolving, a document store avoids the friction of altering tables each time.
Vector Database
A vector database stores embeddings (numeric representations of text, images, or other content) and lets you query them by similarity rather than exact match. This is the piece that powers AI features like semantic search, recommendations, and retrieval-augmented generation (RAG). Having it in the same platform as your document database means you can keep your source records and their embeddings together instead of syncing between two systems.
Authentication
Authentication handles user identity — sign-up, sign-in, and session management — so you don't build credential handling from scratch. This is a standard expectation for any Firebase-style platform, and it's one of the four features Singlebase lists.
Storage
Storage covers file and object handling: images, documents, media, and other binary assets your app needs to upload and serve. Pairing storage with authentication lets you control who can access which files.
How the Features Fit Together
The value of combining these isn't just fewer vendors — it's that the pieces share context. A typical AI-native flow looks like this:
- A user signs in (authentication).
- They upload a file (storage).
- Your app generates an embedding from that content and saves it (vector database).
- Related structured metadata is saved alongside it (document database).
- A later query does a similarity search to surface relevant results.
Because all four live in one platform, you avoid building sync jobs and auth bridges between a document store, a vector store, a file host, and an identity provider.
| Backend need | Singlebase feature | What it replaces |
|---|---|---|
| Structured/flexible app data | Document database | A separate NoSQL service |
| Similarity search & AI retrieval | Vector database | A standalone vector store |
| User sign-in and sessions | Authentication | A third-party identity provider |
| Files and media | Storage | A separate object storage bucket |
Built-in AI Services
Beyond the four infrastructure features, Singlebase describes itself as AI-native with built-in AI services. The vector database is the foundation for that, but the "AI-native" framing means AI capabilities are treated as part of the backend rather than an add-on you integrate separately. If your roadmap includes semantic search or RAG, having the vector store and AI services in the same platform as your data reduces integration work.
When This Combination Fits — and When It Doesn't
It fits if you're building a modern application that needs all four capabilities and wants them from one provider, especially if AI features (search, recommendations, RAG) are part of the plan. The single-platform approach is most valuable when you'd otherwise be wiring together four separate services.
Consider alternatives if you only need one or two of these features — for example, just authentication, or just file storage. In that case a focused single-purpose service may be simpler. Also weigh whether you need a relational database with complex joins and transactions; a document database is a different model and not a drop-in fit for every workload.
What to Verify Before Committing
The platform's own description confirms the four features and the AI-native positioning, but it doesn't specify pricing, free-tier limits, or regional availability. Before you build on it, check:
- Pricing and limits — the source material doesn't state cost or usage caps, so confirm these directly.
- Migration path — if you're coming from Firebase, check how data and auth users transfer.
- Vector search specifics — confirm the embedding dimensions, index types, and query latency your use case needs.
- SDKs and language support — verify client libraries exist for your stack.
Singlebase combines a document database, a vector database, authentication, and storage into one AI-native backend, with built-in AI services layered on top. It's a reasonable fit when you want all four from a single platform and AI features are part of your plan — but confirm pricing, limits, and SDK support against your specific requirements before committing.
