Show HN: LinkedQL – Live Queries over Postgres, MySQL, MariaDB

phrasecode Monday, December 08, 2025

LinkedQL is a new SQL client that supports live queries over any Postgres, MySQL, and MariaDB database. You get result sets that self-update differentially as rows change in your database – via inserts, updates, deletes. Works with no extra tooling/ORM layer or GraphQL servers. You opt into live mode simply with a flag: client.query('SELECT ...', { live: true }). More at: https://linked-ql.netlify.app/capabilities/live-queries

LinkedQL is written in JavaScript and runs in both client and server environments.

GitHub + docs: https://github.com/linked-db/linked-ql

Demo examples included.

I’d love feedback: • Anything confusing? • Anything seems useful or dangerous? • Anything else that'd make you consider LinkedQL for production?

Thanks for taking a look — happy to answer any questions.

Summary
LinkedQL is a GraphQL-inspired query language that allows developers to access and manipulate data across multiple linked databases. It provides a unified interface for querying disparate data sources, simplifying the process of building applications that require data from various databases.
