Maybe — Open Source Personal Finance Manager

What it is

Maybe is an open-source personal finance application that lets you track your net worth, investments, spending, and budgets. It supports bank account syncing, portfolio analysis, and multi-currency tracking. The entire application runs self-hosted via Docker, meaning your financial data never leaves your server.

Maybe is built for individuals who want full control over their financial data. If you currently use Mint, YNAB, or similar SaaS tools but want to self-host, Maybe provides a comparable feature set without subscription fees or data sharing.

How it saves time or tokens

Maybe consolidates financial tracking into a single dashboard. Instead of logging into multiple bank portals and spreadsheets, you connect your accounts once and see a unified view of net worth, spending categories, and investment performance. The self-hosted architecture means no recurring subscription costs.

For developers, Maybe provides a REST API for programmatic access to financial data, enabling custom integrations and automation workflows.

How to use

1. Clone the repository and start with Docker:

git clone https://github.com/maybe-finance/maybe.git
cd maybe
cp .env.example .env
docker compose up -d

1. Open http://localhost:3000 in your browser
2. Create an account and connect your bank accounts or add transactions manually

Example

# Docker Compose deployment with custom environment
git clone https://github.com/maybe-finance/maybe.git
cd maybe

# Configure your environment
cat > .env << 'EOF'
SECRET_KEY_BASE=your-secret-key-here
DATABASE_URL=postgres://maybe:password@db:5432/maybe
REDIS_URL=redis://redis:6379
EOF

# Start the application
docker compose up -d

# Check logs
docker compose logs -f app

After the containers start, the web interface is available at localhost:3000. The first user to register becomes the admin.

Common pitfalls

• Bank syncing requires a Plaid or similar API key. Without it, you need to import transactions manually via CSV. The free tier of Plaid has limitations on the number of connected accounts.
• The Docker Compose setup requires PostgreSQL and Redis. Make sure ports 5432 and 6379 are not already in use on your host machine.
• Maybe is under active development. Features and APIs may change between versions. Pin your Docker image to a specific version in production to avoid unexpected breaking changes.
