Installing on Linux

SubnetSlinger ships on Linux through the standard free app stores, plus a direct download for people who'd rather not use a store.

The basics — pick one:

• Flathub (Flatpak) — works on almost every distribution; auto-updates. The easiest option for most people.
• Snap Store — first-class on Ubuntu and derivatives; also auto-updates.
• Direct .deb / AppImage — from our GitHub Releases page, for Debian/Ubuntu (.deb) or a portable single file (AppImage).

All of these are the free tier out of the box. Pro is unlocked inside the app (a one-time purchase over the web — the store you installed from takes no cut and isn't involved in the payment).

Going deeper: Flatpak and Snap both run the app in a sandbox. That's good for safety but it changes one thing — unprivileged ICMP (see "Ping without root"). If you want raw-socket ping without any caveats, the direct .deb is the most permissive path because it can grant the capability at install time. The AppImage is the most portable (nothing installed system-wide) but you grant capabilities yourself.

Good to know: whichever channel you choose, the app is the same build. Channel only changes how it's delivered, sandboxed, and updated — not what the tools do.
