Kagemusha News

Updates, fixes and announcements for Kagemusha.

Release v1.4.4

Fixed apps that sometimes did not open, and added "Send Your Situation to Support"

After restarting your Mac, for example, opening an app you created sometimes did nothing. This happened because Kagemusha mistakenly judged that the app was still running. Kagemusha now confirms that the app is actually running before making that judgment.

We have also added "Send Your Situation to Support" to the Kagemusha screen in the sidebar. If something is not working, such as an app that does not open, describe what is happening and click Send. Kagemusha attaches information that helps us find the cause, such as its version, the location of Chrome, and the app launch log. Open pages and sign-in information are not sent. You can review what will be sent on screen before sending.

This release also includes two improvements:

  • Settings in the menu bar now shows the Kagemusha window even when it is closed.
  • The confirmation shown when you create an app with an existing name no longer hides behind other windows.

Release v1.4.3

You can now create apps on a Mac without the developer tools installed

On a Mac without the Xcode Command Line Tools, creating an app failed with a "No developer tools were found" error. This happened because Kagemusha built parts of each app on that Mac every time you created one.

Kagemusha now ships with these parts prebuilt and uses them when it creates an app. You do not need to install any developer tools. This works the same on Intel and Apple silicon Macs.

We apologize for the inconvenience. If you could not create an app because of this error, please update Kagemusha to 1.4.3 and try again.

This release also includes two improvements:

  • When an AI agent launches an app in the background, its window no longer flashes to the front.
  • The AI skill now waits 20 to 45 seconds between page navigations on the same site.

Release v1.4.2

You can now create apps on a Mac user account without administrator rights

On a Mac user account without administrator rights, creating an app could fail with a "permission denied" error. This happened because only administrators can write to the Applications folder.

Kagemusha now creates the app in the Applications folder inside your home folder when it cannot write to the Applications folder. Apps created there open from Spotlight and Launchpad as well.

If you have chosen a different location in Settings, Kagemusha keeps creating apps there as before.

We have also updated the icon of the built-in Buffer preset.

Release v1.4.1

You are now notified when an app keeps using the CPU

When one app keeps CPU usage at 50% or more for over 5 minutes, you are now notified with the app's name. If a page left open keeps using the CPU and your whole Mac slows down, you can see at once which app is the cause.

For apps with "Allow AI control" turned on, the notification also shows the name of the heaviest page. From the notification's buttons, you can reload that page or switch it to a blank page.

You can turn these notifications on or off with "Notify when an app keeps using the CPU" in Settings (on by default).

Release v1.4.0

AI control now starts off for new apps

New apps now start with "Allow AI control" turned off.

When you turn it on, a confirmation appears. It asks you to check the terms of the service the app will operate, and not to use AI control on services that prohibit automated operation.

Apps you already let AI operate keep their current setting.

From "AI Integration" in Settings, you can now add one extension to Claude Desktop and operate your Kagemusha apps from it. There is no configuration file to edit.

Notice

We have updated our Terms of Service

We have added a new section 5, "Operation by AI agents", covering the feature that lets AI agents operate your Kagemusha apps.

What an AI agent does is treated as done on your instructions and under your responsibility. You need to follow the terms of the service it operates.

We have also rewritten section 7, "Disclaimer and limit of liability".

The revised terms apply from October 3, 2026.

Release v1.3.9

AI integration now works correctly with agy and Grok

Fixed an issue where agy could not read the skill installed from "AI Integration".

The skill for Grok is now installed in Grok's own folder instead of the folder shared with Claude Code.

We have confirmed that Claude Code, Codex, agy and Grok can each operate your Kagemusha apps.

Release v1.3.8

Now available in 32 languages

Every text in the app is now available in 32 languages.

Kagemusha starts in your Mac's language, and you can choose another one under "Language" in Settings.

In Arabic and Hebrew, the layout runs from right to left.

Release v1.3.7

"AI Integration" now has its own place in the sidebar

"AI Integration" has moved out of Settings into its own item in the sidebar.

Release v1.3.6

Wider app settings, and a fix for lost sign-ins and extensions

The app settings window is now wider and easier to read.

Fixed an issue where apps created from a template profile lost their sign-ins and added extensions every time their settings were saved.

Release v1.3.5

Register extensions once and add them to any app

You can now register Chrome Web Store extensions in Kagemusha and add just the ones you need to any app, including apps you have already created.

"AI integration" now lists each AI agent found on this Mac, and you can install, update or remove the skill for each one. When an existing skill is replaced, the original files are kept as a backup.

Also fixed the update notice overlapping buttons on the Dock screen.

Release v1.3.4

Pages keep drawing and timers keep running while windows are hidden

Apps you create now keep drawing pages and running timers while their windows are hidden or minimized. Services that show clocks or notifications keep working correctly.

Release v1.3.3

"About Kagemusha" now shows the correct version

Fixed an issue where the "About Kagemusha" screen always showed version 1.0.0.

Release v1.3.2

Fixed the permission notice that appeared every time an app opened

Fixed an issue where macOS asked for "App Management" permission every time you opened an app you created.

Release v1.3.1

Fixed switching with Cmd+Tab, and the built-in list now grows without app updates

Fixed an issue where apps you created did not come to the front when chosen with Cmd+Tab.

The list of built-in services is now fetched at launch and every 12 hours, so new services appear without updating Kagemusha.

Release v1.3.0

Added "AI integration" to Settings

You can now install the skill that lets AI agents operate your Kagemusha apps directly from the settings screen.

Release v1.2.0

Your Kagemusha apps can now be operated by AI

AI agents can now operate the apps you create with Kagemusha while they stay signed in.

Only apps you allow are affected. Your everyday browser and any app you have not allowed stay out of reach.

Several apps can be operated at the same time, so multiple tasks can run in parallel.

Release v1.1.6

The app now tells you which settings do not work on Chrome

Google Chrome and Chrome Canary have removed the mechanism that loads extensions passed from outside the browser.

Because of that, when you open a Chrome-based app straight from the Dock or Spotlight, Space mode, window handling, URL rules and the Dock notification badge have no effect.

The settings screen and the create screen now say which of those settings will not work.

To use them, pick Brave, Chromium, Edge, Vivaldi or Opera as the browser.

Release v1.1.5

Intel Macs are supported, and update and sign-in bugs are fixed

Kagemusha now runs on both Apple Silicon and Intel Macs.

Fixed a bug where automatic updates would not start downloading.

Fixed a bug where signing in to Google could fail inside a generated app.

Notice

Kagemusha Pro is now on sale

The free version lets you create up to three apps.

Kagemusha Pro is a one-time purchase ($24.99) that removes the limit.

One purchase covers three Macs.

Release v1.0.0

Kagemusha v1.0.0 released

The first version of Kagemusha, a tool that turns a website into a standalone macOS app on top of Chrome, Brave, Edge and other browsers.
