Frequently Asked Questions

Does Swagger UI Online make external network requests?

It depends on what you're inspecting. Local data is analyzed in-browser; remote URLs require a request to fetch data.

Does this work offline?

After the initial page load, yes — all processing is local. You need connectivity to load the page itself.

Is my data saved after I close the tab?

No. Client-side tools don't persist input. Once you close or navigate away, your data is gone.

Can I bookmark this tool?

Yes — each tool has a stable URL. Bookmark it for quick access anytime.
