SplitDuo

Project information

Shared finances, without the noise. SplitDuo is a lightweight, open-source, self-hosted expense splitting app for small groups / couples, housemates, travel companions, or anyone sharing costs. No subscription, no third-party servers, no data you don't control.

A focused alternative to Splitwise and Cospend, deployable in one docker compose up. Features settlement-aware balances that minimize transfers to settle up, alias mode for subgroup splitting, AI-powered receipt scanning with any OpenAI-compatible endpoint, expense attachments, mobile-first installable PWA, invite-by-email, TOTP 2FA with backup codes, CSV import/export (Splitwise, Cospend, native), per-group stats with charts, full i18n (English and Italian), and an admin panel — all in a single Docker container.
