sablejs compiles untrusted JavaScript into host JavaScript via an AOT step and runs it inside a Web Worker with no access to ambient browser APIs or the host object graph. It exposes only standard ECMAScript objects, copied data, and explicit capabilities. The project targets use cases including LLM-generated transforms, user plugins, rules, formulas, and code playgrounds.
