Little Landlord – Offline Rent Tracker App for Small Landlords

What you get

Stop paying a monthly fee to track a handful of rentals. Little Landlord is a private, offline app for small landlords with 1 to 20 units – a single HTML file that opens in your browser. No installation, no account, no subscription, and your tenants' details never leave your computer.

Each unit hangs on the board as a key tag: paid, due, overdue or vacant – with rent collected this month, who is late, a 12-month chart and upcoming due dates, lease ends and urgent repairs.
