Frappe Books

Frappe Books is a free, open-source desktop accounting software designed for small and medium-sized businesses that need accurate, offline financial management without cloud dependency. It eliminates the complexity and cost of traditional accounting tools by offering a clean, intuitive interface powered by modern web technologies.

Built with Vue.js for the frontend, Electron for desktop packaging, and SQLite for local data storage, Frappe Books runs natively on Windows, macOS, and Linux. It supports full double-entry accounting, point-of-sale transactions, and offline operation—all while keeping user data entirely on the local machine with no cloud uploads.
