GoKawiilPinrail launches as desktop review app for coding agents
A new desktop application called Pinrail lets coding agents such as Claude Code, Codex, Cursor or OpenCode pause at designated steps and request human approval before proceeding. Reviewers see content-specific views, like code diffs or generated images, and their decisions are sent back to the agent as structured Markdown or JSON. The tool currently runs on macOS and Linux, with Windows support planned, and all data stays local via a loopback-only API.
