Swift packages for things that should be hard.
On-device AI, real 3D, live interpreters, and tools for coding with agents. All running on hardware you already own.
If something here is useful to you, a coffee keeps it going.

🩻 VesaliusA map of your codebase for Claude Code, built on your Mac. Vesalius indexes a repository into a graph of files, symbols, references and calls, so your agent can ask "who calls this?" or "where does this feature live?" and get the answer in one step, with file:line evidence, instead of grepping its way there. brew install haplollc/tap/vesalius vesalius setup Across 20 real questions graded blind, Claude Code used about half the tokens, with no measurable change in answer quality. A Mac app and a VS Code extension come with it. |
📱 iOS ErasDrag a ruler from 2007 to 2026 and watch the iPhone rebuild itself. Every stock app arrives in the release it shipped in, every icon is redrawn at every redesign, and the dock, the notch and the Dynamic Island morph from one year to the next. Every position was measured off a real screenshot of that version. |

Dotted, genuinely 3D loading indicators for AI and agent interfaces. Nine hand-tuned designs and two purpose-tuned sizes, drawn only in grayscale dots so they sit quietly in any interface, light or dark. ThinkingOrb(.searching) That is the whole integration. |
🪙 MintedHand it a flat image of a pin and get back a real 3D coin: the artwork becomes the face, the outline is traced from the image, and the gold in the art is detected and rendered as metal that catches the light. let coin = try ArtworkCoin(image: pinArtwork) SpinningArtworkCoinView(coin: coin) No 3D model files. One PNG per pin. |

A claymorphic globe that plants a waving flag on every country someone has visited, and works out where they have been from photo metadata alone. Offline reverse geocoding included, no network and no API key. @StateObject var globe = GlobeManager() ClayGlobeView(manager: globe) await globe.scanPhotoLibrary() |
| Package | What it does | |
|---|---|---|
| 🎨 Mirage | Diffusion image generation on iOS, macOS and visionOS. Embeds stable-diffusion.cpp and ggml-metal, so SD, SDXL, SD3, Flux, Chroma, Qwen-Image and anything else sd.cpp loads runs without a Core ML conversion. |
|
| 🎭 Gepetto | LLM-driven browser automation. A native WKWebView agent loop that navigates, extracts, interacts and screenshots, with the model checking its own work. | |
| 🔥 Forge | A floating SwiftUI debugger for local models. Every token, sampler, grammar mask and tool call, live, over any inference stack. | |
| 🧬 Foundry | On-device LoRA fine-tuning. Personalize a local model from inside your app, while the phone sleeps. | |
| 🕸️ Mesh | Peer-to-peer model federation over the LAN, so an iPhone can borrow the 70B running on your Mac. | |
| ✨ Apparition | One modifier that gives any SwiftUI view AI awareness. .aiAware() and you are done. |
| Tool | What it does | |
|---|---|---|
| 🩻 Vesalius | A code graph built on your Mac that Claude Code and other MCP clients query instead of grepping: who calls what, where a feature lives, what a change breaks. Comes with a Mac app and a VS Code extension. brew install haplollc/tap/vesalius |
|
| ✦ Podium | A local-model terminal coding agent with tools, skills, plan mode and subagents, tuned for small context windows and modest Macs. brew install haplollc/tap/podium |
|
| 📄 md2pdf | A native Mac app and CLI that turns Markdown into pixel-perfect PDFs: tables, highlighted code, LaTeX math, Mermaid diagrams, and page breaks that never slice a line in half. | |
| 🎬 greenscreen-to-hevc-alpha | Strips a green screen from a video and exports HEVC with alpha, Apple's native transparent video, so a looping animation plays in AVPlayer with one line of SwiftUI. |
| Package | What it does | |
|---|---|---|
| 🪙 Minted | Flat pin artwork becomes a physically lit 3D coin, with the gold in the art rendered as real metal. Also mints coins from SVG paths. | |
| 🌍 ClayGlobe | A claymorphic 3D globe that plants flags on visited countries, with offline coordinate-to-country lookups. | |
| 💪 MuscleMapKit | An interactive 3D body that shades each muscle by how hard it was worked, spins under a finger, and reports taps by muscle group. | |
| 🎏 KoiPond | A living koi pond under any SwiftUI view: koi glide over it, lily pads drift on top, and a Metal shader ripples and refracts it all. Tap to feed, drag to stir, or drain it into a pool. | |
| 🌊 LiquidPhotos | Photos that flow into each other: every pixel travels to its place in the next photo, and a shelf of photos flips each one out to meet you. LiquidAlbum($photos) and you are done. |
| Package | What it does | |
|---|---|---|
| 🔮 ThinkingOrbs | Dotted, genuinely 3D loading indicators for AI and agent interfaces. Nine designs, two sizes, one line to drop in. | |
| 📱 iOS Eras | Twenty years of iPhone on one ruler: the home screen and the button from 2007 to 2026, in SwiftUI and in the browser. | |
| 🫧 SiriGlass | The Siri drop from iOS 27 for your own app: Liquid Glass that pours out of the Dynamic Island, listens, and lights up with your voice. .siriGlass($siri) and you are done. |
|
| 🎚️ Scrubbers | Twelve sliders you'll want to touch: jelly, Liquid Glass, fluid, swing, thermostat, mood and more. One view, one enum. | |
| ⏳ ProcessingField | A progress field: a grid of marks whose sizes trace one soft shape that drifts, folds and breathes while your app is busy. | |
| 📝 Markdown | GitHub-flavored Markdown rendered as real SwiftUI views: headings, lists, tables, block quotes, fenced code and images, with a themeable style system. It powers md2pdf's PDF export. |
| Package | What it does | |
|---|---|---|
| 🐍 Terrarium | Python 3.13 embedded in an iOS or macOS app, with on-device pip install and a Pyodide fallback for numpy, pandas, matplotlib and friends. |
|
| 🔥 Kiln | A live Swift and SwiftUI interpreter you can embed anywhere. Hand it Swift source at runtime, get back a real view. No compile step. |
Cloud is expensive, slow, and wants your data. The phone in your pocket is none of those things.
- Private — your data never leaves the device. No telemetry, no API key, no middleware.
- Free to run — no per-token billing on hardware you already paid for.
- Fast — a round trip to a data center costs hundreds of milliseconds you do not have to spend.
- Offline — airplane mode, the subway, a basement. None of it should stop your app.
- Yours — nothing breaks because somebody else had an outage.
Bilbo — a travel app that plans whole trips on device, and turns the landmarks you visit into collectible 3D pins. ClayGlobe and Minted were both pulled out of it.
