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.

Sign-in and approvals through messaging apps for your website or app. No passwords, no forms, no SMS codes - zero typing, even on screens without a keyboard.

The user scans a QR code shown on a computer, TV or any other screen - or taps a button on their phone - and confirms with a single tap in a messaging app they already trust: Telegram, WhatsApp or another supported channel. Veriqa plugs into your application as a standard OIDC provider, with no frontend SDK. Open source under MPL-2.0.
