Open-source, local-first garden operating system built on a horticultural knowledge graph. Native Swift and SwiftUI for macOS.
Croft models a real garden and the knowledge to run it, entirely on your machine. Everything lives in a local SQLite database: no account, no sync service, no network dependency. And the knowledge is accountable: plant relationships cite their sources, so unsourced folklore doesn't get in.
Download Croft-<version>.dmg from the latest release, open it, and drag Croft into Applications. Builds are signed and notarized, so macOS opens them without warnings. Requires macOS 15 or later.
Croft keeps itself current: from 0.2.0 onward the app offers new releases in place through Sparkle, with a Check for Updates item in the app menu. Versions before 0.2.0 need this one manual download first.
- Knows plants. Family down to cultivar, with cultivation profiles covering sun, water, soil pH, spacing, germination, sowing, frost tolerance, and days to maturity: 32 common crops and over a thousand cultivars, bundled offline.
- Knows what threatens them. The major home-garden pests and diseases, what they attack, which cultivars resist them, and identification imagery.
- Maps your garden the way it's actually laid out. Properties contain gardens, gardens contain growing areas and beds (raised, in-ground, or container), and every planting is a real crop in a real bed, traced back to the seed lot or starter batch it came from.
- Remembers what happened. Observations with photos, harvests, and tasks, each connected to the planting, bed, or plant it belongs to.
- Captures fast. Add a planting, log an observation, record a harvest, manage tasks, or add a seed lot from wherever you are, keyboard friendly and prefilled with the current date and your last-used bed and unit.
- Starts your day. A Today screen with local weather and the garden tasks that are due or overdue.
Plant pages cover everything in the bundled catalog: browse, search, and per-plant detail with growing conditions, cultivars, threats, and imagery.
The knowledge snapshot is imported deterministically from pinned, cited sources; knowledge/ documents how it's built. Bundled imagery comes from Wikimedia Commons, iNaturalist, and Flickr under public domain, CC0, and CC BY licenses, with per-image attribution in knowledge/ATTRIBUTION.md.
One typed knowledge graph over SQLite (GRDB). Entities and relationships carry provenance and confidence, single-cardinality edges are enforced with partial unique indexes, and every schema change lands as a migration with preservation tests. The CroftCore package splits into Domain, Persistence, Graph, Knowledge, and feature modules under Core/.
Requires macOS with Xcode 26 or later and mise.
mise install
mise run generate
open Croft.xcodeproj
The Xcode project is generated from project.yml with XcodeGen and is not checked in. Regenerate it after changing project.yml. The macOS app target is Croft-macOS; mise run build also rebuilds the bundled knowledge snapshot.
mise run check
Runs formatting, lint, the package tests, and the macOS app build. mise run check-fast skips the app build for tight iteration; the pre-push gate is the full check. mise run ci adds the runtime design-token resolution tests and is exactly what CI runs.
