A GUI for Hurl

Compiled from Swift — no Electron, no embedded webview, no React. Just SwiftUI and AppKit so it launches fast and feels like a Mac app.
Won't try and abstract your .hurl files into GUI components — you keep writing them as plain text, with syntax highlighting and linting.
Variables captured by one run feed straight into the next, with their provenance shown in the Variables panel so you always know what's set.
Look through a file's run history. Star and rename to persist. Reapply or copy variables captured from historic runs into the current session.
Configure environments backed by one or more .env files, and switch between them from the toolbar or via ⌥1–9 — the active set tints the titlebar.
Open a directory or file straight from the terminal with gurl . — slots into the rest of your shell workflow and editor jumps.
I'm distributing Gurl as a Homebrew cask. I'm currently too tight to pay Apple £99/year, so the install is a two-step to trust the self-signed certificate.
brew install --cask jamesstidard/formulas/gurlxattr -dr com.apple.quarantine /Applications/Gurl.appUpdates are then handled in the app or via Homebrew — both should work and play nice together.
