The record

Purpose: Sentry WMS is a free, open-source warehouse management system built for e-commerce fulfillment.
Scope: It handles warehouse execution—including receiving, storage, picking, packing, shipping, and counting—while connecting those operations to an existing database or ERP.
Picking: Pick Walk supports multi-order batch picking with serpentine walk path optimization.
Inventory: It supports bin-level cycle counts with variance detection and an admin approval workflow, plus inventory transfers and reason-tracked adjustments.
Platform: The documented stack includes a React web admin panel, a React Native (Expo) mobile app, a Flask API, and Docker Compose deployment.
Android app: The deployment guide documents sideloading an APK onto a device and configuring it to connect to the operator's API server.
Security: The deployment guide requires configured secrets for production and documents an encrypted connector credential vault, a hash-chained audit log, content security policy, and rate limiting.
Connector security: Connector security controls include an SSRF guard with DNS-rebinding protection, encrypted credentials that are not returned in plaintext through the API, and audit logging of credential writes.
Deployment requirement: The production deployment guide says HTTPS requires a reverse proxy in front of the HTTP-only API.
Not an ERP: The project states that Sentry is not an ERP and expects an existing system to manage orders, products, or customers.
Limits: The Admin Panel guide states that bulk CSV or JSON imports support a maximum of 5,000 records per import.
License: The repository states that v1.7.0 and later are Apache License 2.0, while earlier tagged releases remain MIT-licensed.
Maker: The repository identifies Hightower Systems L.L.C. as the maker of Sentry WMS.
