On GitHub
Swift packages to drop into an app, and the engines that run AI on the device. Most-starred first.
-
ThinkingOrbs
Dotted, honestly-3D loading indicators for AI and agent interfaces in SwiftUI. Nine hand-tuned designs, two tuned sizes.
-
Minted
Turn any SVG into a physically-lit 3D gold medallion for SwiftUI
-
VesaliusNew
A map of your codebase for Claude Code: an on-device code graph with an MCP server, a CLI, a Mac app and a VS Code extension.
-
MuscleMapKit
Interactive 3D muscle map for iOS. Shade muscles by how hard they were worked, spin the body, tap a group.
-
ProcessingField
A SwiftUI progress field: a grid of marks whose sizes describe one soft shape that drifts, folds and breathes while your app is busy.
-
Gepetto
A browser agent for iOS and macOS that a person can take over at any time. Real WKWebView, small on-device models, a native SwiftUI panel.
-
ClayGlobe
A claymorphic 3D globe for SwiftUI that plants a waving flag on every country you visit
-
Mirage
One-stop on-device diffusion image-generation engine for iOS / macOS / visionOS. Embeds stable-diffusion.cpp + ggml-metal behind a tight Swift API. Supports SD, SDXL, SD3, Flux, Chroma, Qwen-Image, ERNIE-Image, Z-Image, and anything else sd.cpp can load.
-
Scrubbers
Twelve sliders you'll want to touch, for SwiftUI. One view, one enum: Scrubber(.jelly, value: $value). Liquid Glass, jelly, elastic, fluid, squiggle, thermostat, swing, mood and more.
-
SiriGlass
The Siri drop from iOS 27, for SwiftUI: Liquid Glass that pours out of the Dynamic Island and lights up with your voice. One modifier: .siriGlass($state).
-
ios-eras
Drag a ruler from 2007 to 2026 and watch the iPhone rebuild itself. Every home screen, dock, notch and one button, redrawn.
- greenscreen-to-hevc-alpha Strip green-screen from a video and export as HEVC with alpha (.mov), Apple's native transparent-video format.
-
Kiln
Live Swift / SwiftUI interpreter you can embed in any iOS or macOS app. Parses, evaluates, and renders Swift source at runtime, no compile step.
-
Terrarium
Embedded Python 3.13 runtime for iOS/macOS apps with on-device pip install + Pyodide fallback for scientific packages
-
Forge
A floating SwiftUI overlay debugger for local LLMs. Every token, sampler, grammar mask, and tool call, live.
- Apparition One SwiftUI modifier that gives any view AI superpowers. .aiAware() and you're done.
-
LiquidPhotosNew
Photos that flow into each other, for SwiftUI. Every pixel travels to its place in the next photo, and a shelf of photos flips each one out to meet you. One line: LiquidAlbum($photos).
-
md2pdf
Native macOS app that turns Markdown into pixel-perfect PDFs (live preview + high-fidelity exporter)
- retro-remote Retro Remote - A skeuomorphic TV remote control app for iOS
- Foundry On-device LoRA fine-tuning for iOS / macOS. Personalize a local LLM from inside your app, while it sleeps.
-
HaploUI
-
KoiPond
A living koi pond for SwiftUI: koi glide over any view, lily pads drift on top, and a Metal shader ripples and refracts it all. Tap to feed, drag to stir, flip it into a pool. One modifier: .koiPond().
- Markdown A native SwiftUI Markdown rendering engine for Apple platforms. Maintained by Haplo.
- Mesh Peer-to-peer LLM federation over LAN. iPhone borrows your Mac's 70B model over wifi.
- podium A local-model terminal coding agent, optimized for small context windows and modest Macs.
- claude-code-starterNew Starter project pre-wired for Vesalius, the on-device code graph for Claude Code. Clone it, run vesalius setup, and ask Claude Code about the sample code.
- swiftui-starterNew Sample SwiftUI app demonstrating ThinkingOrbs, Minted, and ClayGlobe from Haplo in one view.
On Hugging Face
Open models converted and quantized to run on Apple silicon, and a few we trained ourselves. Downloads are Hugging Face's count for the last 30 days.
Language models 27
Quantized for llama.cpp, small enough to run on an iPhone or a Mac.

-
Cinder
MuscleMapKit was built for Cinder, where its 3D muscle map shows what every workout worked.
