Everyone paid something.Balancia works out the rest.

Yes. An account on this instance costs nothing and no feature is held back. The software itself is free under AGPL-3.0-or-later, so you can also run your own copy and never depend on this one.

No. Invite them through a revocable link. Guests can view the group, add and edit expenses, settle up and upload receipts, but never manage people, links or the group itself.

Add the amount, choose who paid and select the people included. You can split the expense equally, enter exact amounts, assign percentages or use custom shares. Balances update automatically.

Yes. Enter the exact amount for each person, assign percentages or use weighted shares, such as three shares for one person and two for another. Balancia always keeps the total exact.

Keep each currency balanced on its own, or convert into one base currency at a rate frozen when the expense is recorded, so historical expenses are never silently recalculated. Daily rates can be filled in from the European Central Bank's published figures; that is off by default.

Any group downloads as JSON — the complete record, amounts exactly as stored — or as CSV or an Excel workbook, from its settings page.

No. Telemetry never carries personal data or amounts — it exists only to help improve the tool, and on a self-hosted instance it is off by default. Even the category guessing runs locally, with no AI service involved. Optional integrations only make network requests when an administrator enables them. The one thing you can start yourself is connecting an AI assistant to your groups, and it then sees only what you allow.

Yes. Balancia accepts a Splitwise group CSV export or JSON backup. It previews the import before bringing in expenses, repayments, currencies and people. Final shares are preserved as exact amounts, but the original split-method label and historical exchange rates are not recreated.

Balancia is an open-source, self-hostable alternative to Splitwise and Tricount. Its differences include guest participation without an account, progressive web app installation, four split methods, multi-currency groups and Splitwise data import. Features and offers from each service may change.

Yes. Balancia works in a modern browser on desktop, iPhone, iPad and Android. You can also add the progressive web app to your home screen so that it opens like a regular app. It is not distributed through the App Store or Play Store.

Yes. Balancia is an MCP server, so Claude, ChatGPT and other assistants that accept custom connectors can add it by its address and send you to a Balancia screen to sign in and press Allow. There is nothing to install and no key to copy. You choose read only or read and make changes, and every group or just one, and you can disconnect it from Settings at any time. It acts as you, never sees payment details or email addresses, and Balancia itself calls no AI service. Which plans allow custom connectors is up to the assistant's maker.

Yes. Balancia's source code is public at github.com/sebitr/balancia under the AGPL-3.0-or-later licence, where the community can inspect, audit and improve it.

Two commands: download the bootstrap script, then run it. It asks what to enable and starts PostgreSQL, the migrations, the app and its worker with Docker Compose. Reverse-proxy examples for Caddy, Traefik and nginx are in the docs.
