SDK packages & developer tooling

Python and JavaScript packages maintained by Noir Stack / community projects. Use this page to find official Guardrails SDK installs, public registry links, and supporting package surfaces across the Noir developer ecosystem.

Developer platform coverage

Dual SDK distribution makes Noir part of the modern developer toolkit.

Python reaches AI researchers, data scientists, and ML engineers. JavaScript and TypeScript reach web applications, full-stack teams, and high-performance Node.js API consumers. Supporting both ecosystems positions Noir as infrastructure developers can install with the same confidence as their database client, observability agent, or deployment SDK.

Python / pip Captures the AI/ML community where evaluation, research, and model operations already happen.
JavaScript / npm Targets frontend, full-stack, and Node.js teams integrating guardrails into production applications.
Official packages Registry installs feel more trustworthy and maintainable than git clone workflows or raw fetch snippets.
