Wallos is an open source application for tracking subscriptions and recurring expenses. It centralizes all your paid services — streaming, software, insurance, SaaS tools — in a clear dashboard and automatically calculates your consolidated monthly and annual cost, broken down by category and currency.

Its main benefit is preventing forgotten charges: Wallos displays upcoming deadlines and sends notifications before each renewal, via email or through various channels (webhook and notification services). You can then decide in time whether to keep, renegotiate, or cancel a subscription.

Wallos supports multiple currencies with exchange rates, multiple users, custom categories, and provides visual statistics. Self-hosted, the application keeps your financial information strictly private, with no connection to your bank and no transfer to a third-party service.
