Embedded DB Registry

What We're Testing

The Embedded DB Registry benchmarks various embedded database solutions that run directly in web browsers. We measure performance across fundamental database operations to help developers choose the right storage solution for their applications.

Test Operations

• Create Table: Initialize database schema and prepare for data operations
• Insert: Bulk insertion of records to test write throughput
• Select: Query and retrieve records to measure read performance
• Update: Modify existing records to test update efficiency
• Delete: Remove records to evaluate deletion speed

Methodology

Each test runs multiple iterations with configurable record counts to ensure consistent and reliable results. We measure execution time in milliseconds and calculate operations per second for comparative analysis. Tests are performed sequentially to avoid interference and ensure fair comparison across all database engines.

Database Engines Tested

We benchmark SQL databases (LibSQL, SQLite WASM, PGlite, DuckDB), JavaScript databases (LokiJS, Dexie, RxDB), and native browser APIs (IndexedDB, LocalStorage, SessionStorage) to provide comprehensive coverage of available options.
