Awesome GitHub RepositoriesIn-Browser Database Engines

Pglite is a client-side relational database engine that runs a full-featured PostgreSQL instance directly within browser and Node.js environments. By leveraging WebAssembly, it provides a persistent SQL storage solution that enables complex data management and querying without requiring an external database server. The project distinguishes itself through a reactive SQL data layer that automatically synchronizes user interface components with live query results. It manages database operations using worker threads to prevent main-thread blocking and coordinates access across multiple browser t

sql.js is a serverless, in-memory SQL database engine that ports SQLite to WebAssembly for use within a web browser. It provides a JavaScript interface to initialize relational databases, execute SQL queries, and manage structured data without requiring a backend server. The project enables the import and export of database states using typed arrays, allowing in-memory data to be persisted as files. It supports high-precision integer retrieval via BigInt and utilizes prepared statements to increase execution speed and security. The engine includes capabilities for client-side data management

sql-mother is a browser-based educational platform for learning SQL syntax through interactive exercises, tutorials, and a query playground. It provides a structured environment for mastering the logic and syntax of MySQL, SQLite, and PostgreSQL using a sequence of hands-on challenges. The platform uses a WebAssembly-based database engine to enable local SQL execution and real-time query validation entirely within the browser. This architecture allows for virtual table mocking and state management without the need for a backend server or user accounts. The environment includes a gamified cur

Kùzu is an embedded property graph database engine designed for high-performance analytical queries and local data management. It operates as a library within the host application process, utilizing a columnar-based storage architecture and just-in-time query compilation to execute complex graph traversals and pattern matching efficiently. By mapping database files directly into system memory, it ensures data durability and high-speed access while maintaining ACID-compliant transactional integrity. The engine distinguishes itself by integrating vector similarity search and full-text search di

cr-sqlite is a multi-master database replication system that uses conflict-free replicated data types to ensure eventual consistency across distributed nodes. It provides the core capabilities for offline-first data synchronization, allowing multiple database instances to merge concurrent updates and reach a consistent state. The project distinguishes itself through a combination of CRDT-based data replication and a WASM-based database engine, enabling full SQL execution and state persistence within web browsers. It supports peer-to-peer replication and cross-tab synchronization, utilizing ca

SQL Studio is a web-based database management platform designed to provide a unified interface for interacting with multiple relational database engines and structured file formats. It functions as a comprehensive client that enables users to browse database records, inspect schema metadata, and execute custom queries through a centralized dashboard. The platform distinguishes itself by offering both remote database connectivity and serverless, in-browser analysis of flat files such as Parquet and CSV. It incorporates an intelligent code-aware editor that supports syntax highlighting and cont
