Show HN: HostsLab – A Mac app for managing hosts file and SSH config (github.com)

Hey HN! I built HostsLab, a simple desktop app for managing /etc/hosts and ~/.ssh/config on macOS.

I got tired of manually editing config files every time I needed to map a local domain or add an SSH connection. HostsLab gives you a visual interface to:

- Add/edit/disable host entries (with proper sudo handling) - Manage SSH connections with dropdowns for existing keys - Generate new SSH keys (Ed25519/RSA) right from the app - Everything preserves comments and formatting in your config files

It's built with Electron + React + TypeScript, code-signed and notarized, and fully open source (MIT).

Built this mainly for myself but figured other devs might find it useful. Feedback welcome!
