Everything Connected

A coding agent that understands your Mac and your stack.

Built natively for macOS with deep system integration, multi-provider AI, and a tool system that actually works.

AI

Multi-Provider AI

Use Anthropic, OpenAI, OpenRouter, Ollama, or on-device CoreML models with tier-aware access controls.

Local Tool Execution

Run file, shell, git, Docker, browser, cloud deploy, Keychain, OCR, Spotlight, and Xcode tools.

MCP Client & Server

Connect to popular MCP servers, manage credentials in Keychain, and expose G-Rump tools over MCP.

Ambient Code Awareness

Keep project context fresh with file watching, LSP diagnostics, proactive suggestions, and memory.

Flexible Agent Modes

Switch between Standard, Plan, Full Stack, Argue, Spec, and Parallel workflows for every task.

Mac-Native Experience

SwiftUI panels, global quick chat, themes, keyboard shortcuts, and packaging built for macOS.

Developer Workflow

From idea to validated change.

Three simple steps to go from concept to shipped code with full confidence.

01

Plan with context

G-Rump reads project facts, active files, diagnostics, and custom skills before proposing work.

02

Build with tools

Approve safe tool calls, apply diffs, run commands, and coordinate parallel agents locally.

03

Review and ship

Inspect git changes, run tests, export conversations, and prepare release artifacts or DMGs.

Platform

Built for serious macOS development.

G-Rump is a Swift 5.9+ and SwiftUI application for macOS 14+ with a Node.js backend for authentication and OpenRouter proxying. Distributed outside the Mac App Store to support shell execution, language servers, and deep system integration.

Requirements

  • macOS 14 Sonoma or later
  • Swift 5.9+ for local builds
