Pinrail is a desktop inbox where coding agents submit structured approval requests (code reviews, image edits, feedback forms) and wait for human decisions before proceeding. It combines a Rust/Tauri app, a CLI for agents, and a plugin system with HTML views and JSON schemas, keeping everything local via a loopback API. This is an interesting, well-crafted take on human-in-the-loop agent workflows, though the early stage and niche positioning limit its immediate reach.

Target audience: backend devs, AI agent users, devops, product engineers using coding agents
