Portfolio Frame

Product Introduction

1. Overview: Portfolio Frame is a local-first, privacy-focused Chrome extension that functions as a dual-mode editor for creating professional visual assets directly in the browser. It operates within the categories of screenshot mockup tools and code snippet generators.
2. Value: Its primary benefit is enabling developers, designers, and content creators to instantly generate high-quality, styled mockups of screenshots, code, tweets, and device frames without any data leaving their computer, ensuring speed, privacy, and complete creative control.

Main Features

1. Dual Editor Canvas: A unified workspace supporting both image-mockup and code-snippet editing modes. Users can switch seamlessly between pasting a screenshot or a code block while retaining all export controls, annotations, and sizing presets.
2. Advanced Code Snippet Styling: Generates print-ready code visuals using Prism.js for syntax highlighting across languages like JavaScript, TypeScript, Python, CSS, and Rust. Features include macOS/Windows/minimalist window frames, line highlighting, gutters, automatic language badges, and glassmorphism panels with adjustable X/Y/Z tilt for realistic depth.
3. Twitter Snap & Device Mockups: Transforms tweet URLs into clean, styled cards (Tweet cards) with editable stats (replies, reposts, likes) and light/dark themes. Also provides realistic device frames (MacBook, iPhone, Apple Watch) and browser chrome mockups to add contextual scenes to any screenshot.

Problems Solved

1. Challenge: The tedious and insecure workflow of taking a raw screenshot or code block, uploading it to a third-party web service, applying styling, and then downloading the final image—a process that compromises privacy and speed.
2. Audience: Software developers, technical writers, UI/UX designers, and social media managers who need to create polished visual content for portfolios, documentation, blog posts, tutorials, and social media quickly and privately.
3. Scenario: A developer writing a technical blog post needs to showcase a new function. They copy the code from their IDE (VS Code), paste it into Portfolio Frame, apply a Dracula theme with line highlighting, wrap it in a macOS frame, and export a high-resolution PNG—all within their Chrome browser in under a minute, with no data transmitted online.

Unique Advantages

1. Vs Competitors: Unlike cloud-based tools like BrowserFrame or Carbon.now.sh, Portfolio Frame is entirely local-first. It uses the browser's local storage and IndexedDB, meaning zero account creation, zero file uploads, and no server processing, guaranteeing absolute data privacy and offline capability.
2. Innovation: Its technical edge lies in the seamless integration of multiple asset types (code, screenshots, tweets, devices) into a single, lightweight Chrome extension interface. The implementation of client-side rendering for complex visual effects like glassmorphism and 3D tilt without external dependencies is a significant engineering achievement.

2. What image formats and resolutions does Portfolio Frame support for export? The extension allows you to export your mockups as PNG or JPEG files. You have full manual control over the export resolution and JPEG compression level to ensure lossless, high-quality outputs suitable for any platform.
3. Can I use Portfolio Frame to create mockups for social media posts? Yes, Portfolio Frame includes one-click sizing presets optimized for major social media formats, including Square (Instagram), Portrait, Story, Landscape, and Presentation (Twitter/X, LinkedIn), making it ideal for creating promotional content.
