Hitman is a desktop and web SSH connection manager. It keeps an encrypted ed25519/PEM key vault, opens multi-tab xterm.js terminals with resizable split-pane layouts (single / vertical / horizontal / 2x2), organises hosts into connection groups, and supports DoIt OIDC single sign-on with an offline password fallback. Ships as a self-contained Windows installer (bundled Node server, no separate runtime required).
