Relay.

Relay is a desktop API client built with Electron and Vue 3 — a fast, privacy-first alternative to tools like Postman. It runs entirely on your machine with no account, no telemetry, and no cloud sync. HTTP requests are routed through Electron's main process, eliminating CORS entirely.

The interface follows a familiar three-pane layout: a collapsible sidebar with request collections and history, a central request editor with method selector, URL bar, headers/body tabs, and a response pane with syntax-highlighted JSON, status codes, and timing data.

State is managed by Pinia with persistence to the local filesystem via Electron's IPC bridge — workspaces, collections, and request history survive app restarts. The editor supports environment variables with a dot-notation syntax, making it easy to switch between dev and production endpoints without editing individual requests.
