JWKS Viewer: Fetch or paste JWKS. Inspect JSON Web Key Sets. Shows metadata, headers, timing, and structure that aren't visible at the surface — essential for debugging unexpected behavior. Client-side architecture: your input is processed locally and never persists beyond the browser tab. In the JWT tools on HttpStatus.com — works in any modern browser.
It depends on what you're inspecting. Local data is analyzed in-browser; remote URLs require a request to fetch data.
Many tools support shareable links. Look for the share button after processing your input.
Client-side tools use your device's memory, so they handle up to several megabytes. Very large inputs may slow the tab.
