Install Cody — Developer Mode

The Chrome Web Store version is coming soon. Meanwhile, you can install Cody in Developer Mode in 30 seconds — no store needed.

Download Cody Extension (.zip)

Version 1.0.2 · Built April 16, 2026 · Chrome MV3

How to install

1
Download and unzip

Click the button above to download cody-chrome-latest.zip. Unzip it — you'll get a folder called chrome-mv3. Put it somewhere you won't accidentally delete it (e.g., your Desktop or Documents folder).

2
Open Chrome and go to chrome://extensions

Type chrome://extensions in the address bar and press Enter. (You can't click a link to chrome:// pages — you have to type it.)

Select the chrome-mv3 folder

Done — Cody is installed

Cody should now appear in your extensions list and in the Chrome toolbar. If you don't see the icon, click the puzzle-piece icon in the toolbar and pin Cody from the list.

Troubleshooting

“This extension may have been corrupted”

You downloaded the wrong file, or tried to load the zip directly. Make sure you unzipped the download first, then select the resulting chrome-mv3 folder — not the zip file itself.

The Cody icon doesn't show in the toolbar

Click the puzzle-piece icon (⚖) in Chrome's toolbar, find Cody in the list, and click the pin icon to pin it.

Chrome says “Extensions are disabled”

Developer-mode extensions can be temporarily disabled by Chrome after a restart if your Chrome is managed by an organisation. Re-enable Developer Mode on chrome://extensions each time, or ask your IT admin to allow sideloaded extensions.

This is a beta build. If something goes wrong, open an issue on GitHub or email rob@withcody.com. Once Cody lands on the Chrome Web Store, you'll be able to install it the normal way.
