Getting Started

Prerequisites

Bun
Docker and Docker Compose

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

Fork and clone the repository

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

Start the database and Redis:

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

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
