Tartanleaf Open Source

Free & Open-Source Tools

Practical software that makes everyday technology simpler — free to download, inspect, adapt, and share.

Technology That Stays Understandable

Tartanleaf develops small, practical tools around real problems. They are free community resources rather than subscription services or supported commercial products.

HomeNetCheck + homenet

One home-network diagnostic project, with two ways to use it. Both check common problems such as router reachability, DNS, double NAT, latency, internet speed, and Wi-Fi, then explain what the results mean.

  • HomeNetCheck is the graphical desktop app for Windows, macOS, and Linux. Download it, open it, and click Check my network.
  • homenet is the command-line engine for scripts, automation, remote support, and people who prefer a terminal.

HomeNetCheck downloads are not code-signed, so your operating system may show a first-run warning. The opening instructions explain why and what to check.

For small hospitality spaces

Open Lobby Board

A local-first welcome board for hotels, inns, B&Bs, restaurants, event venues, and reception spaces. It runs on a Raspberry Pi connected to a lobby display, while staff update the board from a phone or computer on the same trusted local network.

There is no subscription, cloud account, advertising service, database, or hosted dependency. The sample content remains set in Baddeck, Nova Scotia, where the project was originally developed for Gisele’s Inn.

Free and open source · MIT License · Locally controlled

This is an example project for technically comfortable operators. It is designed for a trusted, non-routable local network and must not be exposed to the public Internet.
