In their own words
Sentry WMS
Sentry WMS is a free, open-source warehouse management system for e-commerce fulfillment. It covers receiving, storage, picking, packing, shipping, and counting, while relying on an existing database or ERP to manage orders, products, or customers. Pick Walk supports batch picking across multiple orders with serpentine walk path optimization. Inventory functions include bin-level cycle counts with variance detection and an administrator approval workflow, along with transfers and adjustments tracked by reason. The connector framework provides a starting structure for ERP, commerce, and other HTTP API connections, but the project does not ship first-party connectors for named systems such as NetSuite, QuickBooks, Shopify, or BigCommerce. The documented stack includes a React web admin panel, a React Native mobile app, a Flask API, and Docker Compose deployment. Android setup uses a sideloaded APK connected to the operator's API server. Production deployment requires configured secrets; HTTPS requires a reverse proxy in front of the HTTP-only API. CSV or JSON bulk imports are limited to 5,000 records per import. Version 1.7.0 and later are Apache License 2.0; earlier tagged releases remain MIT-licensed.
