OpenKOS

Open-source property management platform for boarding houses (kos), apartments, and rentals. Self-hosted, extensible, and built with Laravel + React. OpenKOS handles the full rental lifecycle — properties, units, leases, tenants, invoices, payments, rent reminders, and maintenance — with a plugin architecture that lets you extend without forking. - Properties & Units — Manage multiple properties with unit-level tracking, capacity, rates, and availability - Leases & Tenants — Flexible leases with multi-tenant occupancy, billing intervals, and automated rent scheduling - Invoices & Payments — Payment tracking with proof upload, manual confirmation, and overdue detection - Rent Reminders — Automated WhatsApp reminders with configurable scheduling and manual one-off sends - Maintenance — Ticket-based maintenance tracking with status workflow (reported → in-progress → resolved) - Multi-Property Support — Dashboard, reports, and settings scoped per property - Role-Based Access — Owner, admin, and staff roles with granular Spatie permissions - Plugin Architecture — Extend via plugins (navigation, dashboard, settings, workspace tabs, notification drivers, payment gateways) - WhatsApp Integration — Pluggable WhatsApp driver system with a built-in log driver and optional integrations Sign-in: this app keeps its own accounts. Each member signs up or signs in inside the app with an app username and password; the hub remembers each member's session. First account: made when the app is installed (owner), with a password the hub generates; the hub's owner reads it on the app's Access tab, then sign in at /login. OpenKOS is the open-source project senatroxx/OpenKos (https://github.com/senatroxx/OpenKos) by senatroxx, released under Apache-2.0. Ion packages it unmodified from commit aeb354411dad, adding only a manifest, an icon and a start script.

Not rated. Nobody has said who this app is suitable for, so Personal Clouds and the Oikou app treat it as 18+.

Internet

It asks to reach these hosts, and no others:

• inertiajs.com
• marketplace.openkos.id

While your Personal Cloud builds it, the build asks to download from:

• registry.npmjs.org
• registry.yarnpkg.com
• pypi.org
• files.pythonhosted.org

Sign-in details your Personal Cloud makes

The Personal Cloud makes a sign-in password for this app when it is installed. Only you can read it, on the app’s Access tab on your Personal Cloud. Oikou never sees it.

• admin-password — The password of OpenKOS's first administrator account, made when the app was installed (account: owner)

Its address

Works best with its own address. A Personal Cloud shared through Cloudflare can give it one; on a private Personal Cloud on Tailscale it opens under your Personal Cloud’s address, where it may not work fully. Private and shared Personal Clouds
