Goldie Releases CLI for Automated App Store Screenshot Generation

Goldie is a CLI tool that integrates with coding agents to automatically generate screenshots and preview videos for app stores. Unlike existing tools that use image generation models, it leverages Software Mansion's argent to replay and capture actual user flows on iOS Simulator or Android Emulator.

Key Features and Compatibility

• Automation Pipeline: Composites device frames, backgrounds, and headlines onto captured screens and validates store upload specifications (pixel dimensions, video duration, etc.).
• Framework Support: Supports SwiftUI, UIKit, Jetpack Compose, Flutter, React Native, Kotlin Multiplatform, and more.
• Agent Integration: Generates and modifies configuration files within the repository to automate repetitive tasks, and integrates with Cursor, Codex, Claude Code, and others.

Platform-Specific Assets and Limitations

• iOS: Requires a macOS (Xcode/iOS Simulator) environment. Screenshots for the iPhone 17 Pro Max are generated at 1320x2868, and preview videos at 886x1920 in H.264 format.
• Android: Google Play assets can be generated on Linux/Windows, but the devices setting must retain only pixel-10-pro. Since the Play Store does not allow video uploads, Goldie renders vertical preview videos for YouTube posting.
• Caution: Release builds are recommended to prevent LogBox banners in debug builds, and re-recording argent flows or agent repairs may be necessary when the app changes.

Installation and Usage

Requires Node 20.12+ and ffmpeg, installed via npm i -g goldie. After checking the environment with goldie doctor, run the full pipeline with goldie all or modify design options via the browser UI with goldie studio. It is licensed under MIT, allowing free personal and commercial use.
