Overview
G-Rump is a macOS-native AI coding agent written in Swift/SwiftUI — 54,000+ lines. It brings multi-model AI, more than 100 local development tools, 58 MCP presets, and six agent modes into a fast desktop app built for Mac developers. Public source on GitHub with a live product site.
The Challenge
Most AI coding assistants live in a browser tab, bill per seat, and never touch the machine where the work actually happens. Mac developers wanted something native, fast, and private.
The Solution
A SwiftUI desktop app: multi-model AI with 100+ local development tools, 58 MCP presets, and six agent modes — the agent works where the code lives instead of the other way around.
