AI Architecture Analysis

This repository is indexed by RepoMind. By analyzing OpenCut-app/OpenCut in our AI interface, you can instantly generate complete architecture diagrams, visualize control flows, and perform automated security audits across the entire codebase.

Our Agentic Context Augmented Generation (Agentic CAG) engine loads full source files into context on-demand, avoiding the fragmentation of traditional RAG systems. Ask questions about the architecture, dependencies, or specific features to see it in action.

Source files are only loaded when you start an analysis to optimize performance.

Getting Started

Prerequisites

Note: Docker is optional but recommended for running the local database and Redis. If you only want to work on frontend features, you can skip it.

Setup

  1. Fork and clone the repository

  2. Copy the environment file:

    # Unix/Linux/Mac
cp apps/web/.env.example apps/web/.env.local

# Windows PowerShell
Copy-Item apps/web/.env.example apps/web/.env.local

  3. Start the database and Redis:

    docker compose up -d db redis serverless-redis-http

  4. Install dependencies and start the dev server:

    bun install
bun dev:web

The application will be available at http://localhost:3000.

The .env.example has sensible defaults that match the Docker Compose config — it should work out of the box.

Self-Hosting with Docker

To run everything (including a production build of the app) in Docker:

docker compose up -d

The app will be available at http://localhost:3100.

Contributing

We welcome contributions! While we're actively developing and refactoring certain areas, there are plenty of opportunities to contribute effectively.

🎯 Focus areas: Timeline functionality, project management, performance, bug fixes, and UI improvements outside the preview panel.

⚠️ Avoid for now: Preview panel enhancements (fonts, stickers, effects) and export functionality - we're refactoring these with a new binary rendering approach.

See our Contributing Guide for detailed setup instructions, development guidelines, and complete focus area guidance.

Quick start for contributors:

  • Fork the repo and clone locally
  • Follow the setup instructions in CONTRIBUTING.md
  • Create a feature branch and submit a PR
