Plant a seed and watch it grow.
A tiny, calm macOS app for starting new projects β made for late nights, brain resets, and fresh beginnings. π
Notarized by Apple Β· macOS 26+ Β· drag to Applications and go
Some nights you don't want a dashboard. You just want to start something.
Seedling lives quietly in your menu bar. Summon it β a click, or β₯βS β and a small window fades into the center of your screen: just a seed in the dark, waiting for a name. Type one. Watch a little line-art seedling draw itself and bloom. Your new project is alive.
That's the whole thing. That's the point.
Every project starts from the same handful of files β your rules and guidelines. AGENTS.md, CLAUDE.md, README, TODO, SECURITYβ¦ the DNA a project grows from.
In Seedling, those files are your seeds, kept in a folder you call your Root. Name a new project and Seedling plants a fresh copy of them into your Garden β and a new folder is born. Tend your seeds whenever you like; every future project grows from the latest version.
π° Root β where your seed files live π³ Garden β where new projects grow πΏ Plant β name a project, and it sprouts, seeded and ready
It never overwrites anything. Re-plant into a patch that already exists and the old files stay untouched.
- A seed in the dark β one quiet field: name your project
- It grows β the line draws itself, then a single breath of light
- Enter the garden β your new folder opens, and the window fades away
No menus to wade through. No settings page pretending to be a workflow. Just a moment.
The easy way β download the latest .dmg, open it, and drag Seedling to Applications. It's signed and notarized by Apple, so it opens with no security warnings. (Or browse all releases.)
From source β it's a native macOS app (SwiftUI, built for macOS 26 with Liquid Glass):
open Seedling.xcodeproj # then βR in XcodeEither way: look for the leaf πΏ in your menu bar. On first run it asks where are your seeds? then take me to your garden β after that it's just β₯βS, a name, and grow.
Requires macOS 26 (Tahoe) or later.
One pastel-sage accent, hairlines, Liquid Glass, no drop shadows β and a single belief: starting a project should feel like a new beginning, not a chore.
For the curious β the technical bits
A focused menu-bar app: no main window, no networking, ~16 small Swift files. Sandboxed with security-scoped bookmarks, a Carbon global hotkey, and a Finder "Seed this folder" service on the side. The growth is pure SwiftUI line-art (no image assets), and the whole flow lives in a centered, key-accepting NSPanel.
