Overview

Lets the Aethern API tester send requests to your own computer and local network, without CORS. Only after you allow each host.

Aethern - API tester is the companion extension of the API tester in Aethern. The API tester runs in your browser. A web page cannot reach an API on your own computer or your local network: the browser stops it (CORS, mixed content, local network access). This extension sends those requests for the tester, so you can test an API on localhost, on a server in your office or behind your VPN, straight from the portal. How it works - In the API tester, choose "Send through the browser extension". - The extension asks once whether the portal may use it. - The first request to a host opens a window of the extension that asks whether it may reach that host. Nothing is allowed in advance. - The answer comes back in the tester like any other: status, headers, body, duration. What it does not do - It never sends cookies along with a request. - It never reads or changes the pages you visit. It has no content scripts. - It never stores a request, a header or an answer. It keeps only that the portal may use it, and your language. - It sends nothing to Aethern or to anyone else. A request goes to the host you addressed and nowhere else. - Only the Aethern portal can talk to it. No other website can. You stay in control The settings list every host the extension may reach. Remove a host, or stop the portal from using the extension, at any time. You need an Aethern account with the API tester to use this extension.
