AppMarquee

<div align="center"> <img src="plugins/appmarquee/assets/icon.svg" width="84" alt="AppMarquee logo" /> <h1>AppMarquee</h1> <p><strong>Your store-screenshot studio—built for people and agents.</strong></p> <p>Create, review, localize, and export App Store and Google Play screenshot decks from one local workspace. Give agents the screenshots, not your source code.</p>

The short version

Most screenshot generators begin as code inside each app repository. AppMarquee is one reusable program instead:

1. Create a project in AppMarquee.
2. Upload real product screenshots.
3. Ask Codex, Claude, or another MCP agent to build the story.
4. Review visually and export every required store size.

The agent never needs the app’s source directory. Your project files and screenshots remain local.

What ships

Studio	Agent bridge	Output
Multi-project dashboard + bulk import	Codex plugin + MCP server	App Store iPhone and iPad sets
Connected or isolated canvas	Claude Code and generic MCP setup	Google Play phone and tablet sets
Drag, resize, rotate, reorder	Visual screenshot reading	1024×500 feature graphics
Themes and localized copy	Revision-safe targeted updates	Language-selectable PNG ZIP bundles

Quick start

Requires Bun 1.1+ and Node.js 20+.

git clone https://github.com/furkangonel/AppMarquee.git
cd AppMarquee
bun install
bun run mcp:build
bun run dev

Open http://127.0.0.1:3000.

Connect Codex

bun run mcp:install:codex

Connect Claude Code

bun run mcp:install:claude

Connect Claude Desktop

bun run mcp:install:claude-desktop

Completely quit and reopen Claude Desktop after installation. See the complete Claude Desktop guide for manual configuration, verification, removal, troubleshooting, and Desktop Extension status.

Restart the agent, then ask:

Check AppMarquee status. Inspect the screenshots in Focus Garden and create
a six-screen iPhone deck in English and Turkish. Validate it when finished.

That is enough. You can launch the agent from another folder; the generated MCP configuration uses an absolute path.

For plugin marketplace installation, generic MCP JSON, verification, and removal instructions, see the complete installation guide.

Designed for a real launch workflow

01 — Bring the product proof

Select or drop several simulator, emulator, or device captures in one pass. AppMarquee sorts them by filename, fills empty screens, and adds screens up to the active store limit. Assets use content-addressed filenames and stay inside that local project.

02 — Let the agent shape the narrative

The agent can view uploaded screenshots, write benefit-led copy, choose layouts, localize text, and replace only the requested device deck. Revision checks prevent stale agent writes from silently replacing newer human edits.

03 — Keep the final visual decision human

Reload agent changes in the editor, adjust anything visually, choose exactly which project languages to download, and export exact PNG bundles. AppMarquee supports iPhone, iPad, Android phone, 7-inch tablet, 10-inch tablet, and Google Play feature graphics.

MCP tool surface

Tool	What it lets an agent do
appmarquee_status	Confirm that the local studio is available
appmarquee_list_projects	Discover local projects without a directory path
appmarquee_create_project	Start a new launch workspace
appmarquee_get_project	Read project state and its current revision
appmarquee_list_assets	Find uploaded product screenshots
appmarquee_read_asset	View an uploaded screenshot as image content
appmarquee_update_device_deck	Replace one device deck without touching the others
appmarquee_update_settings	Change name, theme, canvas mode, or locales
appmarquee_validate_project	Check structure and Apple/Google screen limits
appmarquee_project_link	Return the exact local visual-review URL

Why it stays light

AppMarquee avoids keeping every full-resolution screen alive at once. The editor renders detail only around the active slide, uses schematic sidebar thumbnails, keeps a decode-only image cache, captures each export source once, and streams uncompressed PNGs into the ZIP. See Architecture.

projects/ is ignored by git by default. Publishing this repository does not publish local screenshot projects.

Development

bun run check          # unit tests + MCP bundle + production application build
bun run mcp:test       # real stdio client smoke test (studio must be running)

Open-source lineage

AppMarquee is an independent open-source continuation of Parth Jadhav’s original app-store-screenshots project. The editor foundation remains MIT-licensed; AppMarquee adds a multi-project workspace, local project API, lower-memory rendering, revision-safe MCP tools, plugin packaging, and the new product identity.
