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.

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.
