Changelog — MockShot Studio

Drive MockShot Studio from the terminal and AI tools

2026-11-13T00:00:00Z

You can now drive MockShot Studio from outside the app window.

Install: npm install -g mockshot-studio, then run mockshot pair and allow the dialog in the app.
CLI: status, open/save documents, update slides, free previews, and full-size PNG export that uses the same allowance as exporting in the app.
MCP: Claude Code, Claude Desktop, Cursor and other MCP clients can call the same tools over stdio while you watch the edits in the app.

The connection stays on this Mac only (127.0.0.1), and you can revoke access anytime with mockshot unpair or File > Connected Tools….

Privacy policy updated — we now use PostHog analytics on the web editor and this site

2026-11-13T00:00:00Z

We updated the Privacy Policy (section 7, Analytics) because we added a second analytics tool, PostHog, next to Google Analytics 4. We want to see how many people use the web editor, the landing page and this changelog, and which features help them.

What changed

Where: the web editor, the landing page and pages such as this changelog.
What may be collected: device and browser information, the pages you view, and events such as importing a screenshot, exporting, adding a slide, changing the language, and errors.
A cookie: an anonymous ID so a visit that starts on the landing page and continues in the editor is counted once.

What we do not collect

We do not record your screen or your session.
The contents of your images and the text you type in the editor are not sent.
Your email address is not sent to the analytics tools.

Mac app

The Mac app does not send analytics to us. That has not changed.

Handles keep their size when you enlarge a device frame

2026-11-11T00:00:00Z

When you scaled up a device frame or a Mac window on the canvas, its crop and rotate handles grew along with it. At large sizes they covered the screenshot you were trying to line up.

The handles now stay the same size on screen at every scale, so they remain easy to grab without getting in the way.

Crop handles: same size at any scale, in and out of crop mode.
Rotate handle: keeps a fixed size and a fixed distance from the frame.

Projects opened from the library save again on Mac

2026-11-11T00:00:00Z

In the Mac app, a project opened from the Projects library could be edited but not saved. Saving showed an error and left the file unchanged. Your edits on screen were kept, but they were not written to disk.

This is fixed in 1.1.0 (37). Projects in your library save in place again. Projects opened with File → Open… were not affected.

If you hit this error before updating, your project file still holds its last successful save. Update to the latest TestFlight build, then save again.

Mac purchases no longer time out, and your plan is one click away

2026-11-07T00:00:00Z

Purchase timeout: if the App Store purchase sheet stayed open for more than 20 seconds, for example while you entered your password, the app showed a purchase error. It now waits up to about 10 minutes for you to finish.
Your plan: click the plan indicator at the bottom right to see whether you have Pro — unlimited exports or how many free exports are left. Clicking it as a Pro user used to do nothing.
Remaining exports: the app could say your free exports were used up while some were still left. It now shows the correct count.

Clearer notifications, now at the top of the screen

2026-11-05T00:00:00Z

Wording: notifications no longer include internal codes. Each one says what happened and, when needed, what to do next, in English and Japanese.
Position: notifications now appear at the top center of the window instead of the bottom, where they covered the slide strip and blocked clicks.
Fewer interruptions: switching slides no longer shows a notice that the device changed. Only warnings about heavy cropping or overlap remain.

Saving works after replacing an image on a duplicated slide

2026-11-05T00:00:00Z

After duplicating a slide, replacing or clearing an image on one of the two copies caused saving to fail with Save failed. This affected screenshots, zoom callout images and custom background images. Each copy now keeps its own image, and saving works.

When the side panel was narrow, the theme button grew taller and the Export PNG label overflowed its button. Long labels are now shortened, and the full text appears when you hover.

Crop device frames from the left and right

2026-11-04T00:00:00Z

Alongside Crop top/bottom, there is now Crop left/right. Use them together to show exactly the part of the device you want.

On the canvas: double-click the device to enter crop mode, then drag the bars at the edges.
In the side panel: set the start and end in percent.
In the export: the cut edges are drawn with the same slit as top and bottom crops.

The crop is saved in your .mockshot file.

The feedback dialog opens in the middle of the screen again

2026-11-01T00:00:00Z

Clicking Feedback opened the dialog inside the left panel, where it was cut off and could not be used properly. It now opens in the middle of the window, above the canvas, and Esc closes it.

Screenshot sizes and frames for iPhone Duo

2026-11-01T00:00:00Z

MockShot Studio now supports the iPhone Duo screenshot category in App Store Connect.

Submission sizes: iPhone Duo (Outer) at 1398×2034 and iPhone Duo (Inner) at 2007×2853.
Device frames: Star White and Night Sky, with your screenshot fitted to each display.
Pickers: with more choices, the iPhone devices and App Store sizes now open as menus.
Orientation: the orientation switch is now a button that rotates the device 90° at a time.

This shipped first in the Mac beta. The browser editor received it on November 4.

Photo backgrounds now appear in Mac app exports

2026-10-29T00:00:00Z

In the Mac app, exported PNGs could replace photos with a solid color, even though the editor showed them correctly. This affected:

photo background presets
background images you chose yourself
Mac window wallpapers

Photos are now drawn into the export, with the text, menu bar and devices on top as in the editor. The browser editor was not affected.

A Projects library in the Mac app

2026-10-29T00:00:00Z

Version 1.1 of the Mac app adds a Projects library.

One folder: choose a folder the first time you save. New projects are saved there without a save dialog.
Library: open File → Projects… to see your projects, open them, rename or delete them, or show them in Finder.
Save As: asks only for a new name and saves it in the same folder.

The app keeps access only to the folder you chose.

Mac window fixes: correct orientation and a ready-made default layout

2026-10-24T00:00:00Z

Orientation: in the Mac app, the Mac window could appear rotated to portrait, and the rotate handle turned only its contents. The window now stays landscape and rotates as a whole.
Default layout: choosing Mac as the device used to show an empty window. It now applies the Sequoia wallpaper layout with a sample headline, which you can then edit.
Label: the device option is now named simply Mac.

Mac app 1.0: unlimited exports with a one-time Pro purchase

2026-10-22T00:00:00Z

Version 1.0 of the Mac app adds the purchase model for the Mac App Store.

Three free exports: try the full app, including export, before buying.
Pro — Unlimited Exports: a one-time in-app purchase through the App Store. No subscription.
Restore Purchases: brings Pro back on another Mac signed in with the same Apple ID.
Requirement: macOS 13 or later.

In the TestFlight beta, purchases use Apple's test environment and testers are not charged.

Make Mac App Store screenshots with a Mac window

2026-10-22T00:00:00Z

MockShot Studio can now make screenshots for Mac apps. Choose Mac as the device and the board switches to the Mac App Store size, 2880×1800.

Window and menu bar: your screenshot sits in a macOS-style window, and the window frame and menu bar are included in the exported PNG.
Wallpaper: pick one of ten desktop photos. The wallpaper and window move together, and you can change their size, position and corner radius. The board background stays separate.
Layouts: five layouts measured for Mac screenshots, for example with the headline on the left or above the window.

This shipped first in the Mac beta. The browser editor received it on November 1.

Web credit packs are now priced in US dollars

2026-08-23T00:00:00Z

Credit packs for the browser editor are now priced and charged in US dollars, so the price you see is the price you pay wherever you are. Your card issuer may convert the amount to your local currency.

Credits you already bought are counted the same way as before and remain in your balance. The Mac app is not affected.

Fixes for saved screenshots, rotation and spans

2026-08-16T00:00:00Z

A round of fixes shipped between August 14 and 16 (Mac builds 14 to 22):

Saved screenshots: screenshots could show as broken when a saved .mockshot file was opened, especially in the browser and for HEIC photos from iPhone. Images are now saved in a format both editors can display, and HEIC is converted to PNG.
Moving to the browser: Continue in Browser could open an empty canvas. It now always saves first and opens a screen for receiving the file.
Rotation: a rotated device could appear upright after opening the file in the other editor.
Breaking a span: the device on the second slide could be left outside the board. It now returns to the center.
Resetting position and scale: now moves the device back to the center.
Slide arrows: in light mode, the arrows next to the slides were hard to see and sat too low.

Continue a project between the browser and the Mac app

2026-08-14T00:00:00Z

You can now pick up the same project in either editor.

From the browser: Continue in App saves the project as a .mockshot file. Open the downloaded file in the Mac app.
From the Mac app: Continue in Browser saves the project, shows it in Finder and opens mockshot.studio, where you open the file.
Drag and drop: dropping a .mockshot file onto the editor opens it.

The file stays on your computer. Nothing is uploaded to move it between editors.

Spans match the store's gutter; headline and caption are added separately

2026-08-14T00:00:00Z

Store gutter: on App Store and Google Play product pages, screenshots are shown with a small gap between them. Spans now leave room for that gap, so the device lines up when the screenshots are shown in the store. Turn off Compensate store gutter for a seamless span instead. Existing files keep their saved layout.

Headline and caption: each can now be added or removed independently, like the rating tile. A slide can have only a caption, only a headline, or neither. Removing one keeps its size, position and color for when you add it back.

Web credits can top up automatically

2026-08-14T00:00:00Z

When you buy credits in the browser editor, you can now opt in to auto-purchase.

When it runs: only when your balance reaches zero during an export. It buys the same number of packs with your saved card and continues the export in the same click.
If your bank asks for verification: you are sent to the regular checkout to confirm.
Turning it off: click the remaining-count line under the export buttons and change the setting.

Auto-purchase is off unless you choose it, and the Terms describe the amount, frequency and how to cancel.

The editor is now available in English and Japanese

2026-08-13T00:00:00Z

The whole editor is now available in English and Japanese: menus, side panels, dialogs, notifications and the purchase screens.

Browser: switch with JA | EN in the footer.
Mac: switch from View → Language.
First launch: follows your system language. A language you choose yourself is remembered.
Sample text: the default headline and caption, and the layout preset thumbnails, follow the selected language. Text you have edited is never replaced.

Rotate devices to any angle and span one across slides

2026-08-13T00:00:00Z

Two new ways to compose a device:

Free rotation: drag the rotate handle above the device, or set Angle in the side panel. The rotation is kept in the exported PNG.
Span across slides: choose Span with next slide to stretch one device and its screenshot across neighboring slides. Viewed side by side in the store, they read as one continuous image. Add more slides with Add next slide to span, or undo it with Break span.

While a span is active, the slides in the editor are shown without gaps so you can see the joined result.

Send feedback from inside the editor

2026-08-13T00:00:00Z

You can now send feedback without leaving the editor. Click Feedback at the bottom of the left panel, next to the theme switch.

Message: the only required field.
Name: optional.
Screenshot: optional. Drop an image, click to choose one, or paste it.

Messages go straight to the team and are used to fix problems and decide what to build next.

You can drag a device frame again after adding a screenshot

2026-08-10T00:00:00Z

After you placed a screenshot in a device frame, the frame could no longer be dragged on the canvas. You can now grab the screenshot itself to move the device, and double-click it to start cropping. The replace and remove buttons on the screenshot still work.

In the browser editor, following a link that leaves the page now asks before discarding unsaved changes. The About, Privacy, Terms and Contact links open in a new tab so your editing session stays open.

Web exports now use prepaid credits

2026-08-09T00:00:00Z

PNG export in the browser editor now works with prepaid credits. Editing and saving stay free.

One credit per export: exporting one slide or all slides at once uses one credit.
Sign in by email: enter your email and open the link we send. There is no password.
Remaining count: shown under the save and export buttons once you are signed in.
Restore your balance: sign in with the same email on another browser or computer.

Payments are handled by Stripe. The Mac app is not affected.

Double-clicking a .mockshot file in Finder opens it

2026-07-25T00:00:00Z

In the Mac app, double-clicking a .mockshot file in Finder, or choosing Open With → MockShot Studio, opened the app with an empty document. Opening the same file with Open… worked.

Files opened from Finder now load correctly, both when the app is starting and when it is already running. If you have unsaved changes, the app asks before replacing them.

MockShot Studio launches: store screenshots in your browser and on Mac

2026-07-19T00:00:00Z

MockShot Studio is now public. It is a tool for one job: turning your app's screenshots into store-ready images at the exact size App Store Connect and Google Play Console ask for.

The browser editor runs at mockshot.studio, and the Mac app is available as a TestFlight beta.

Submission sizes: pick an App Store or Google Play preset and the board and export size follow it.
Device frames: iPhone and Pixel frames, with your screenshot fitted to the screen.
Layout presets: start from a finished composition instead of a blank board.
Headline and caption: with highlight and box markup for the words that matter.
Zoom callouts: enlarge a detail of the screenshot next to the device.
Crop: cut the device at the top or bottom with a clean slit.
Multiple slides: build the whole set and export every slide at once.
Local files: save your work as a .mockshot file. Your images are processed on your computer and are not uploaded.

The editor needs a computer-sized window. On phones and narrow windows it shows a link you can copy and open on a computer.
