Start time, memory and disk

Porticol 0.1.0, Yaak 1.0.0, Insomnia 13.3.1 and Bruno 4.2.1, each on a fresh profile and on the first screen it opens to, launched once to set up and then five times, with the median shown. Time to first window runs from launch until the app's first window is on screen. Memory is the footprint Activity Monitor reports, summed over every process the app runs, including the system web view's, 30 seconds after launch. App size is the application bundle on disk. Chrome 155.0.8059.80 was measured the same way with one blank tab and no extensions, at 384 MB. Postman is not in this run yet. The machine is one laptop, not a lab.

• The machine is one laptop, an Apple M4 Pro with macOS 26.4, not a lab.
• Each app was measured on a fresh profile, at the first screen it opens to.
• A number moves with a version, a profile and an extension. Compare these apps with each other, not with a number from another page.
• The measurements are of the desktop apps alone; they say nothing about a server or a hosted workspace.
