Never drag a window again
Tessa tiles your windows and gets out of the way. Nine desktops, one keystroke each. Split or master-and-stack per desktop. Independent desktops on every display. It uses only the macOS Accessibility API. No SIP changes, no kernel extensions, no Terminal. Every shortcut, gap and rule is a switch in a settings window, not a line in a config file you have to learn first. The config file exists if you want it. 14-day trial. One-time purchase, two Macs, no subscription.
Tessa is a macOS developer tool that simplifies window management by allowing users to tile windows across multiple desktops with customizable shortcuts. It operates using the macOS Accessibility API without requiring system modifications and is available as a one-time purchase for use on two Macs.
A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
