A modern, resource-efficient app for analyzing your personal finances built with Rust.

The primary use case is running this program as a self-hosted Docker instance accessed locally or via VPN. Your data stays yours! There is currently no support for multiple users.

• Transaction tracking with categories, tags, and multi-currency support
• Spending analytics with interactive charts (Sankey diagrams, category breakdowns, time series)
• Investment portfolio tracking with positions, realized/unrealized gains, and market data from Yahoo Finance
• Net worth calculation and historical trends
• Automatic categorization via pattern-matching rules
• Bulk import/export of transactions and trading activities from CSV
• Dark mode and customizable settings
• Progressive Web App installable on Android and iOS

Take it for a spin! To start up an instance with some demo data:

docker run --rm --init -p 7070:7070 \
    -e SOLVENCY_PASSWORD_HASH=DANGEROUSLY_ALLOW_UNAUTHENTICATED_USERS \
    ghcr.io/adrianvollmer/solvency-demo:latest

Also works with Podman!

Then navigate your browser to http://localhost:7070.

• Web Framework: Axum 0.7
• Templates: Askama (compile-time checked)
• Interactivity: HTMX
• Database: SQLite with SQLx
• UI: Tailwind CSS
• Background Jobs: tokio-cron-scheduler

All environment variables are prefixed with SOLVENCY_. Create a .env file:

SOLVENCY_DATABASE_URL=sqlite://solvency.db
SOLVENCY_PORT=7070
SOLVENCY_HOST=0.0.0.0
SOLVENCY_PASSWORD_HASH=<argon2-hash>
RUST_LOG=info

The SOLVENCY_PASSWORD_HASH environment variable is required. Set it to an Argon2 hash of your password:

# Using argon2 CLI tool
echo -n "your-password" | argon2 $(openssl rand -base64 16) -id -e

(Or use https://argon2.online/.)

To explicitly allow unauthenticated access (e.g., for local-only deployments), set:

SOLVENCY_PASSWORD_HASH=DANGEROUSLY_ALLOW_UNAUTHENTICATED_USERS

The app will refuse to start if SOLVENCY_PASSWORD_HASH is unset, empty, or invalid.

The easiest way to run Solvency is with Docker (or Podman).

docker compose up -d

The app will be available at http://localhost:7070 with persistent storage.

There is a publicly available Docker image: ghcr.io/adrianvollmer/solvency:latest

To build the image:

docker build -t solvency .

Run the container:

docker run --rm -d \
  -p 7070:7070 \
  -v solvency-data:/app/data \
  -e SOLVENCY_DATABASE_URL=sqlite:///app/data/solvency.db \
  -e SOLVENCY_PASSWORD_HASH='$argon2id$...' \
  -e SOLVENCY_PORT=7070 \
  -e SOLVENCY_HOST=0.0.0.0 \
  --name solvency \
  solvency

• SOLVENCY_DATABASE_URL: Path to SQLite database (default: sqlite:///app/data/solvency.db)
• SOLVENCY_PORT: Port to listen on (default: 7070)
• SOLVENCY_HOST: IP address to bind to (default: 0.0.0.0)
• SOLVENCY_PASSWORD_HASH: Required. Argon2 hash for authentication, or DANGEROUSLY_ALLOW_UNAUTHENTICATED_USERS to disable auth
• RUST_LOG: Log level (default: info)
