Installing the Hermes extension

The Hermes – Trendyol Product & Competitor Tracking extension is not on the Chrome Web Store for now. Download it from this page and install it in Chrome yourself in a few steps.

Download the extension (.zip)For Google Chrome and Chromium-based browsers (Edge, Brave, Opera).

Installation steps

Download and unzip the file. Open the downloaded hermes-extension.zip; it contains a hermes-extension folder. Move this folder to a permanent place (for example Documents).
Open the extensions page in Chrome. Type chrome://extensions in the address bar and press Enter.
Turn on Developer mode. Switch on the "Developer mode" toggle in the top-right corner of the page.
Load the folder. Click "Load unpacked" and select the folder that contains manifest.json (the hermes-extension folder). Hermes appears in the extensions list.
Give consent and open Trendyol. Right after installing, Hermes opens its data consent page; read it and accept. Then sign in with your godsofsale.com account and open a Trendyol product page: the Hermes card appears on the page.

Good to know

Chrome may show a "Disable developer mode extensions" warning each time it starts. Click "Cancel" and Hermes stays on.
Updates are not automatic. When the Hermes panel asks for a new version, download the new zip from this page, extract its files over your existing hermes-extension folder and click the reload (↻) button on Hermes at chrome://extensions.
Don’t delete or move the folder. Chrome runs the extension from it; if the folder is deleted or moved, Hermes stops working and you need to repeat step 4.
To uninstall, open chrome://extensions and click "Remove" on Hermes; you can then delete the folder.
