One engine, many tools – Introducing Rubydex
Rubydex is a new portable static analysis engine designed to unify Ruby tooling by providing a single API for code indexing and type analysis. It aims to improve performance and correctness across various tools that rely on code indexing. Built with Rust, C, and Ruby, Rubydex allows for easy integration with other languages and platforms.
- ▪Rubydex serves as a foundational building block for creating various Ruby tools.
- ▪It can collect definitions, index RBS documents, and track references within a codebase.
- ▪Rubydex is designed for portability, allowing developers to create tools in different languages.

Opening excerpt (first ~120 words) tap to expand
One engine, many tools — Introducing Rubydex 2026-05-12 • Vinicius Stock One engine, many tools A few years ago, the new Ruby parser Prism was released. One of its primary goals was to unify the community since we had multiple implementations of Ruby parsers, each with their own bugs, differences in implementation and portability. By having a single parser, community investments in performance and correctness benefit every single tool built on top of it (including Ruby itself!). However, the story of repeated implementations of highly complex foundational blocks doesn’t end at the parser level. Move one level up the stack and the pattern repeats. Today, we have multiple tools that implement code indexing and related static analysis algorithms.
