SpecLynx
An open source API tooling project, Apache-2.0 throughout, for authors and maintainers of OpenAPI, AsyncAPI and Arazzo — a VS Code OpenAPI toolkit, a browser editor, a CLI and a language service, all built on ApiDOM, its semantic parser. ApiDOM ships a dedicated Arazzo 1.x namespace plus JSON and YAML parser adapters, so an Arazzo document becomes a structure you walk rather than text you match; the Arazzo Toolkit and Jentic's parser are built on it. Maintained by Vladimír Gorej and contributors, with no paid tier.

Where it applies
Jobs this tool actually does, and the surface each one is exercised on.
Install the ApiDOM Arazzo namespace plus the parser adapter for the serialisation you hold.
The editor and VS Code toolkit run locally; specifications never leave the machine.
