+embedded database
+
+
+
+**from llm**
+
+Yes — there are several **SQLite-like databases** that:
+
+* ✅ Store everything in a **single file**
+* ✅ Don’t require a central server
+* ✅ Can store **BSON / document-style data** (instead of strict tables)
+
+Here are the best options depending on what you want:
+
+---
+
+## 1️⃣ **LiteDB** (Very close to what you described)
+
+* Embedded
+* Single `.db` file
+* No server required
+* Stores data as **BSON documents**
+* Very similar to MongoDB API
+* Great for .NET apps
+
+If you're using C#, this is probably the cleanest choice.
+
+---
+
+## 2️⃣ **MongoDB + Embedded Alternatives**
+
+MongoDB itself requires a server, BUT there are embedded variants:
+
+### 🔹 **Realm**
+
+* Embedded
+* Local file storage
+* Document-style
+* Good for mobile apps
+
+### 🔹 **NeDB**
+
+* Pure JS
+* Stores data in a file
+* Mongo-like API
+* Good for Node.js apps
+
+---
+
+## 3️⃣ **UnQLite**
+
+Very interesting option:
+
+* Embedded (like SQLite)
+* Single file
+* No server
+* Key-value + document store
+* JSON-like storage
+* Written in C
+
+This is probably the closest SQLite-style NoSQL engine.
+
+---
+
+## 4️⃣ SQLite itself (with JSON)
+
+Even regular **SQLite** supports:
+
+* JSON columns
+* JSON queries
+* Single-file database
+* Zero configuration
+
+If you just need document-style storage without strict schema, SQLite + JSON might already be enough.

+
+| DB      | File-based | Serverless | BSON/Document   | Best For     |
+| ------- | ---------- | ---------- | --------------- | ------------ |
+| LiteDB  | ✅          | ✅          | ✅ BSON          | .NET apps    |
+| UnQLite | ✅          | ✅          | ✅ JSON-like     | C / embedded |
+| NeDB    | ✅          | ✅          | ✅ JSON          | Node.js      |
+| SQLite  | ✅          | ✅          | JSON (not BSON) | General use  |

+
+* What language you’re using
+* Desktop / web / mobile?
+* Approx data size?
+
+I can give you a more precise recommendation.
