Show HN: VillageSQL = MySQL and Extensions

metzby Thursday, February 05, 2026

INSTALL EXTENSION vsql-complex; CREATE TABLE t (val COMPLEX);

Look, MySQL is awesome [flamewar incoming?]. But the ecosystem has stagnated. Why?

No permissionless innovation. Postgres has flourished because people can change the core of the database (look at pgvector and pg_textsearch), without having to get their changes accepted upstream.

(This, btw, is what powered GitHub's early success: you can fork a repo and make changes without needing the owners' approval)

VillageSQL is a tracking fork of MySQL (open source, ofc) that adds an extension framework: * Drop-in replacement

* Add custom data types and functions (with indexes coming soon)

* we wrote example extensions (vsql-ai, -uuid, crypto, etc.)

* you have a better idea for an extension

* my CEO submitted a Show HN post but linked to the announcement blog; help me show him hackers want code first

* I'm particularly proud of the friendly C++ API to add custom functions (in func_builder.h)

(Oh, and I get to work with the former TL of Google's BigTable and Colossus, so we care about doing databases Right)

Summary
VillageSQL is an open-source, distributed SQL database that focuses on high availability, fault tolerance, and ease of use. It provides a scalable and reliable platform for hosting and managing SQL databases in a decentralized manner.
