openapi.tanna.dev, a client-side OpenAPI Viewer
As noted in my article, Running Elements API Viewer to Verify Local OpenAPI/Swagger Documents, it can be handy viewing OpenAPI files locally.
This is really useful for the case that we've got proprietary, or maybe at least not-yet-ready specifications to view.
Now, I want people to remember to never trust online tools. Even though I wrote this tool, and have made it available for usage, I still want y'all to remember to consider your own threat profile.
