Code Interactive Archiving Extension and Desktop App is a JavaScript based system for high-fidelity web archiving directly in the browser. The system can be used as a Chrome/Chromium based browser extension and also as an Electron app.

The system creates, stores and replays high-fidelity web archives stored directly in the browser (via IndexedDB).

For more detailed info on how to use the extension (and the app when it is available), see the: User Guide

The initial app release is available on the Releases page


The extension makes use of the Chrome debugging protocol to capture and save network traffic, and extends the UI and the wabac.js service worker system for replay and storage.

The codebase for the extension and Electron app is shared, but they can be deployed in different ways.

Requirements Building

To developer, Node 12+ and Yarn are needed.

Using the Extension

The production version of the extension is published to the Chrome Web Store

For development, the extension can be installed from the wr-ext directory as an unpacked extension. If you want to make changes to the extension, it should be installed in this way. This will be a different version than the production version of the extension.

  1. Clone this repo

  2. Open the Chrome Extensions page (chrome://extensions).

  3. Choose 'Load Unpacked Extension' and point to the ./wr-ext directory in your local copy of this repo.

  4. Click the extension icon to show the extension popup, start recording, etc...

Development Workflow

For development, it is recommended to use the dev build of the extension:

  1. Run yarn install and then ``yarn run build-dev`

  2. Run yarn run start-ext -- this will ensure the wr-ext directory is rebuilt after any changes to the source.

  3. After making changes, the extension still needs to be reloaded in the browser. From the Chrome extensions page, click the reload button to load the latest version.

  4. Click the extension icon to show the extension popup, start recording, etc... The dev build of the extension will be grey to differntiate from the production version.

Using the Electron App (in beta)

The Electron app version is in beta and the latest release can be downloaded from the Releases page

To run the Electron app development build:

  1. Clone this repo.

  2. Run yarn install and then yarn run build-dev

  3. Run yarn run start-electron to start the app.

The Electron App version will open recording in a new window. It is is designed to support Flash, better support for IPFS sharing. However, it is still in development and may not work yet until the initial release is out.

Development workflow

After making changes, rerun yarn run build-dev and yarn run start-electron to load the app.

Standalone Build

To create a platform-specific binary, run:

yarn run pack

The standalone app will then be available in the ./dist/ directory.
