What it is

Sentry WMS is a free, self-hosted warehouse execution system for e-commerce businesses that already use a system of record or ERP. It handles receiving, storage, picking, packing, shipping, and counting, including multiple warehouses. Teams can batch orders for picking with serpentine walk-path optimization. Inventory tools include bin-level cycle counts with variance detection and admin approval, plus adjustments and transfers. Barcode lookup from the mobile app home screen can identify items, bins, purchase orders, or sales orders. An inbound API accepts updates for sales orders, items, customers, vendors, and purchase orders using source-specific YAML mappings and scoped WMS tokens. Its connector framework is intended for ERP and commerce platforms, but operators or developers must build the connectors; first-party ones are planned for v2.0.0. The documented deployment uses Docker Compose, a Flask API, PostgreSQL 16, a React admin panel, and a React Native Expo mobile app. The public project is under Apache-2.0 and documents encrypted connector credentials, a hash-chained audit log, and SSRF protections.
