It's a native desktop app for Windows, macOS, and Linux that lets you: - Create a named environment per project and apply it in a few seconds - Flush DNS with one click (runs the correct command per OS) - Auto-backup before every apply, so you can restore your hosts file if something breaks - Handle large hosts files (1000+ entries) with instant search and IP validation
It's a one-time purchase (4.99 €) with lifetime updates no subscription. There's a 3-day free trial (no credit card) and an interactive demo on the site.
Happy to answer questions about the approach, the DNS-flush handling across platforms, or the Team setup.
