⚡ A single PHP file. < 400 lines of code. No database. No background processes. No cloud. Just works. ⚡

🚀 Why uSentry?

Most IAM and SSO solutions require databases, certificates and background services baked into a dozen containers. This is all fine but also also overkill for homelabs and impossible for low-power ARM devices. uSentry is different, it isn’t pretty but it sucks less for a lot of use cases:

• 🧱 Single PHP file with less than 400 lines of code — Easy to read, easy to audit, easy to deploy
• 🍃 No persistent processes — Nothing running in the background, no wasted resources
• 💡 Designed for low-power devices — Runs perfectly on a Raspberry Pi or similar
• 💾 No database required — All users stored right into the code
• 🌐 Privacy-focused — Offline first, 100% local, no cloud, no external services, no internet access required
• ⚙️ Define users and permissions — Control access per user and per app (domain, url)
• 🕵️ SSO-ready — Authenticate once, access all apps
