SpecLynx OpenAPI Toolkit
The OpenAPI Powerhouse for VSCode
The OpenAPI Powerhouse for VSCode
SpecLynx OpenAPI Toolkit is a purpose-built VSCode extension for OpenAPI authors, designed to work seamlessly wherever you code — whether on desktop VSCode, in the browser with vscode.dev or github.dev, or inside GitHub Codespaces. No setup headaches, just powerful OpenAPI authoring at your fingertips in any environment.
SpecLynx OpenAPI Toolkit is engineered for clarity, control, and confidence, enabling you to focus on designing exceptional APIs.
Get full YAML/JSON autocompletion, inline documentation hints, validation, linting, and live preview as you type — so you catch errors before they cost you time. OpenAPI Toolkit surfaces context-aware suggestions for paths, parameters, responses, components, ...; flags missing or mismatched fields instantly; and renders a side-by-side spec-to-UI preview that updates with every keystroke. Say goodbye to manual spec checks and hello to a fluid authoring experience that keeps your API specs accurate and up-to-date.
All these commands — and more — are just a keystroke away in VS Code, so you can focus on designing great APIs instead of wrestling with tooling.
We believe in building SpecLynx in the open. Here’s our public roadmap, so you can see what’s coming next and what we’re working on:
