Sentry WMS - Free, open-source warehouse management for e-commerce

by•
Most WMS platforms cost $500-2,000/month per warehouse. Sentry is free forever. Open-source, scan-driven warehouse management built for e-commerce. Runs on industrial barcode scanners. Receiving, put-away, pick walks, pack verification, shipping, cycle counts, bin transfers, and inventory adjustments. Built by a warehouse manager from real floor experience. 307 automated tests, MIT licensed. One command to deploy with Docker. Python/Flask, React, React Native, PostgreSQL.

Hey PH! I'm Michael, a warehouse manager at an e-commerce company. I built Sentry WMS because every warehouse management system on the market costs $500-2,000/month and none of them are open source. For small to mid-size e-commerce operations, that pricing is insane -- and the enterprise products are built for warehouses 10x the size of what most online stores actually run. I manage a real warehouse floor -- 8,000 orders/month, 5 scanning stations. Every feature in Sentry comes from operational problems I solve daily, not from a product roadmap written in a conference room. Scan the PO, scan the items, complete the receive. Scan the SO, verify the items, print the label. No 40-field data entry forms. No enterprise bloat. Hardware-tested on industrial barcode scanners (Chainway C6000) with broadcast intent scanning -- not a webcam in a browser. 307 automated tests. All SQL parameterized. Non-root containers, random admin password on first run, login lockout, JWT invalidation on password change. One command to deploy with Docker. MIT licensed. Free forever. I'd love feedback -- especially from anyone running warehouse operations, building logistics tools, or evaluating WMS options for their store. GitHub: https://github.com/hightower-sys...
