How Indragie Karunaratne developed a macOS app using Claude Code

8 July 2025

San Francisco based developer Indragie Karunaratne:

I recently shipped Context, a native macOS app for debugging MCP servers. The goal was to build a useful developer tool that feels at home on the platform, powered by Apple’s SwiftUI framework. I’ve been building software for the Mac since 2008, but this time was different: Context was almost 100% built by Claude Code.

Karunaratne has extensively documented the process. Of the twenty-thousand lines of code that make up the app, he estimates he wrote about one-thousand lines. Cluade Code did the rest.
