PUBLIC REPOSITORIES
Open source
We ship the pieces we would otherwise rewrite on every project. 16 public repositories: an LLM eval harness, Swift packages used inside our own apps, and small tools for the chores around a launch.
AI and agents
Evaluating models, calling them, and teaching agents a codebase.04konkordPYTHONLLM eval harness that measures whether its own judge can be trusted. Bradley-Terry ratings, bootstrap intervals, and the judge-versus-human agreement rate published beside every leaderboard.LIVE LEADERBOARD →REPOSITORY
chatbot-enginePYTHONReusable RAG and tool-calling chatbot engine that holds zero product state: the system prompt, model, tools and documents arrive with every request, and the engine calls the app's own tools back over MCP. Two evaluation harnesses ride along, LLM-as-judge for the system prompt and retrieval metrics (hit-rate, recall, MRR) for RAG.SwiftAIKitSWIFT5 ★One async/await interface across OpenAI, Anthropic and Apple Intelligence. Streaming, JSON mode, and the key kept in the Keychain.Swift-Agent-SkillMARKDOWN5 ★A reusable agent skill for Swift work: focused guidance, references and workflow scaffolding a coding agent can follow.Swift packages
The parts of an iOS app you would otherwise write again on every project.09MarkdownEditorKitSWIFT10 ★SwiftUI Markdown editor with live syntax highlighting and a formatting toolbar, built on UITextView.MetalCustomShadersSWIFT7 ★Custom Metal shaders for image processing and filtering.MonthCalendarKitSWIFT3 ★Lightweight month calendar for SwiftUI with custom day cells, theme injection and swipe navigation.AppleSignInKitSWIFT3 ★Sign in with Apple behind a SwiftUI-friendly API, with Keychain storage handled.GoogleSignInKitSWIFTGoogle's GoogleSignIn-iOS SDK wrapped in a strongly typed async/await API.SwiftNetworkingKitSWIFT2 ★Enum-driven async/await networking.

MainActor observable object, cached state, offline fallback.SwiftHeatmapKitSWIFT1 ★SwiftUI heatmap with four intensity levels, configurable week start and themeable colours.SwiftReviewKitSWIFTDrop-in SwiftUI review prompt with rate, feedback and dismiss actions. Fully themeable.
Tools
Small Python utilities for the parts of shipping that are pure chore.03swiftgen-scaffoldPYTHON4 ★Interactive scaffolder that drops SwiftGen config, stencils and the required folders into any iOS project.appstore-snapshotsPYTHONA Python alternative to fastlane deliver for App Store screenshots, with per-device folders and automatic locale mapping.panorama-slicerPYTHONCLI and library for cutting panorama images into vertical 9:16 slices, with custom ratios and overlap.
