Lab13 shelf — both shipping apps

Mon, 18 May 2026 11:20:00 GMT

Two Mac apps are on the shelf right now: Offsend and Promptix. Both target macOS 13 Ventura or later, run on Apple Silicon and Intel, are signed and notarized, and are free to try. Nothing here tracks you; if something breaks, e-mail hello@lab13.io.

One more app is under construction — no public name yet, probably shipping this year. Want an early build? Drop a line to hello@lab13.io.

Internal memo: Herbert the tab (easter egg)

Mon, 18 May 2026 10:48:00 GMT

Herbert is Lab13's honorary tab character. He has no roadmap, no OKRs, and flawless indentation. If your reader strips whitespace, apologize to Herbert quietly.

FAQ: Does this feed support push? (easter egg)

No servers, no push — it's a static XML file next to the landing export. If you wanted live psychic release alerts, try refreshing the old-fashioned way; it builds character and saves battery.
