App

New Expensify is a ground-up rewrite of the expense management platform, built as a React Native app that runs on iOS, Android, web, and desktop from a single codebase. It handles expense reports, receipt scanning, corporate card management, invoicing, and bill pay.

The open source angle is interesting: Expensify publishes their entire client app on GitHub, which is rare for a fintech company. But this is not a tool you self-host. It is the client for Expensify's paid service. Contributing is encouraged but the product only works with Expensify's backend. Alternatives like Fiskl and Budget Zen exist for personal expense tracking, but for corporate expense management the real competitors are SAP Concur, Brex, and Ramp.

The catch: open source client, closed source backend. You cannot run your own Expensify. This is transparency, not freedom.
