# sqlite-graph: Competitive Analysis
2+
3+
## Overview
4+
5+
This document compares sqlite-graph to other SQLite-based graph databases and JavaScript graph libraries to understand our competitive positioning and unique value proposition.
6+
7+
## SQLite-Based Graph Databases
8+
9+
### simple-graph (Python/Multi-language)
10+
11+
**Repository**: https://github.com/dpapathanasiou/simple-graph
12+
13+
**Approach:**
14+
- Schema-only library providing SQL templates and statements
15+
- Nodes as JSON objects with unique IDs
16+
- Edges as directional pairs of node IDs with optional properties
17+
- Uses SQLite Common Table Expressions (CTEs) for graph traversal
18+
- Inspired by "SQLite as a document database"
19+
20+
**Language Support:**
21+
- Python (PyPI package: `simple-graph-sqlite`)
22+
- Go, Julia, R, Flutter/Dart, Swift
23+
24+
**Philosophy:**
25+
- Provides SQL schema and prepared statements rather than unified API
26+
- Developers integrate into their chosen language using native SQLite bindings
27+
- Trades specialized optimization for accessibility and simplicity
28+
29+
**API Style:**
30+
```python
31+
# SQL-based approach with templates
32+
# Developers write SQL queries using provided schema
33+
```
34+
35+
**Comparison to sqlite-graph:**
36+
37+
| Feature | simple-graph | sqlite-graph |
38+
|---------|--------------|--------------|
39+
| API Style | SQL templates | Fluent TypeScript API |
40+
| Language Focus | Multi-language | TypeScript/JavaScript |
41+
| Abstraction Level | Low (SQL) | High (fluent methods) |
42+
| Type Safety | None | Full TypeScript generics |
43+
| Query DSL | SQL/CTE | Method chaining |
44+
| Developer Experience | Raw SQL | Intuitive API |
45+
| Performance | Depends on SQL skill | Optimized queries |
46+
47+
**Our Advantage:**
48+
- Modern fluent API vs raw SQL templates
49+
- Type-safe TypeScript with generics
50+
- Better developer experience with method chaining
51+
- Built-in graph algorithms (BFS, shortest path)
52+
- Natural relationship syntax: `createEdge(from, 'KNOWS', to)`
53+
54+

import Graph from 'graphology';
134+
135+
const graph = new Graph();
136+
graph.addNode('alice', { name: 'Alice', age: 30 });
137+
graph.addNode('bob', { name: 'Bob', age: 25 });
138+
graph.addEdge('alice', 'bob', { type: 'KNOWS' });
139+
140+
// Traversal
141+
import shortestPath from 'graphology-shortest-path';
142+
const path = shortestPath(graph, 'alice', 'bob');
143+
```
144+
145+

## Unique Value Proposition of sqlite-graph
226+
227+
### 1. Best of Both Worlds
228+
229+
sqlite-graph combines:
230+
- **SQLite reliability**: ACID transactions, file-based persistence, battle-tested storage
231+
- **Modern API**: Fluent TypeScript DSL with method chaining
232+
- **Graph semantics**: Natural relationship syntax and graph algorithms
233+
234+
### 2. Developer Experience
235+
236+
```typescript
237+
// Natural, readable syntax
238+
const path = db.traverse(alice.id)
239+
.out('KNOWS')
240+
.filter(node => node.properties.age > 25)
241+
.shortestPath(bob.id);
242+
243+
// vs raw SQL in simple-graph
244+
// vs Cypher learning curve in Neo4j
245+
// vs in-memory-only in graphology
246+
```
247+
248+
### 3. Zero Dependencies Beyond SQLite

253+
- Works in Node.js, Electron, browser (with WASM)
254+
255+
### 4. Type Safety with Generics
256+
257+
```typescript
258+
interface Person {
259+
name: string;
260+
age: number;
261+
}
262+
263+
const person = db.createNode<Person>('Person', {
264+
name: 'Alice',
265+
age: 30
266+
});
267+
// TypeScript ensures type correctness
268+
```
269+
270+
### 5. Embedded-First Philosophy
271+
272+
- **Use Case**: Personal knowledge management, local-first apps, embedded systems
273+
- **Example**: Obsidian plugins, Electron apps, CLI tools, mobile apps
274+
- **Benefit**: No network latency, works offline, simple deployment

373+
- Less expressive than Cypher for complex pattern matching
374+
- Slower than in-memory graphs for pure computation
375+
376+
**Strategic Position:**
377+
sqlite-graph is the **best SQLite-based graph database for TypeScript/JavaScript developers** who need persistent graph storage with a modern, type-safe API.
