Lets Specbook pages call the APIs you allow from your browser, even when the API blocks browsers (CORS). Specbook turns an OpenAPI spec into live documentation you can run. On a hosted page such as ui.specbook.dev, the browser stops a page from reading most APIs' answers (CORS). This extension makes the call for the page, so a live request works there as it does under specbook dev. You stay in control: • Installing asks for nothing. The extension has no access to any site until you grant it. • Each API address is allowed separately, in Chrome's own dialog, for the site that asked. Another site cannot reuse it. • Calls are read-only until you turn on changes for that API. • No cookies, no redirects followed, no private addresses unless you enable them, 30 requests a minute per API. • It stores no keys: the keys a request needs stay in the page, for that tab only. • No analytics, no telemetry, no account, no remote code. You do not need it for an API on the same origin as the page, for APIs that send CORS headers, or under specbook dev. Open source (MIT): https://github.com/specbook-dev/specbook
