Open Source Projects

We use local AI to build things. Here are some of the open-source projects built exclusively with local models.

TerrapinPilot Xcode integration

TerrapinCode

GPL-3.0

Swift

A privacy-first local ACP server that runs agentic OpenAI-compatible local LLMs on your Mac. Written in Swift, designed for Xcode — but usable from any ACP-compliant IDE.

  • Runs locally on your Mac — no cloud, no telemetry
  • Speaks the Agent Client Protocol (ACP) over stdin/stdout
  • Works with any OpenAI-compatible endpoint: llama.cpp, LM Studio, mlx
  • Supports skills, session persistence, and context compaction
Calgary static site generator

Calgary

MIT

Swift

A static site generator where the build pipeline is Swift code. Write your content in Markdown, define your build as a few lines of Swift, and let Calgary assemble the rest.

  • No config files — your build is Swift code in your repo
  • Markdown pages with YAML frontmatter, HTML templates, and reusable components
  • Built-in localization, sitemap generation, and link checking
  • Used to build this very website
