Personal finance tracker that consolidates accounts, investments, and assets into a single net worth dashboard with goal tracking and projections.

Maybe is a personal finance app focused on tracking net worth over time. It pulls together your bank accounts, investment portfolios, real estate, and other assets into one place so you can see your full financial picture without juggling spreadsheets or multiple apps.
It's built for individuals who want more visibility into where their money sits and where it's headed. The core experience centers on net worth tracking, but it extends into budgeting, transaction history, and financial goal planning.
Key capabilities include:
Maybe is self-hostable, which matters if you'd rather keep sensitive financial data on your own infrastructure instead of a third-party cloud. That's a meaningful distinction from most personal finance tools, which store everything on their own servers with limited transparency.
The app is built with a clean interface aimed at making financial data approachable rather than overwhelming. It targets people who want a serious overview of their finances without the complexity of tools designed for accountants or financial advisors.

Privacy-focused personal finance app using envelope budgeting, multi-device sync, optional end-to-end encryption, and bank sync for US, EU, and UK users.

Actual Budget is a personal finance management tool built around envelope budgeting, the method where you assign every dollar you actually have to a specific category before spending it. No projected income, no made-up numbers. You budget what's in your accounts right now, which keeps your plan grounded in reality.
It's local-first by design. Your data lives on your device, and the app works fully offline. Sync happens in the background across as many devices as you want, but a dropped connection doesn't stop you from using it. For people who've grown uncomfortable with cloud-first finance tools, that's a meaningful distinction.
Key capabilities:
The interface is intentionally minimal and fast. Categorizing transactions, reviewing spending, and moving money between envelopes are all optimized to take as few taps or clicks as possible. Dark mode and system-level theming are built in.
Actual is self-hosted. You run the sync server yourself, which means your financial data never touches a third-party service unless you choose bank sync. Among budgeting apps that offer this level of privacy, few match its combination of polished UI and full local control.
An all-in-one personal finance platform. Track, optimize, grow, and manage your money through every stage of life.
