Show a single Windows application window in any web browser on LAN

Ever needed to show one app window on a tablet without any remote-desktop software?

I built WindowStream for exactly that, and Ive just open-sourced it.

Its a small Windows tray app that streams a chosen window as MJPEG over HTTP on your local network. On the tablet or other PC you just open a browser: nothing to install, and its strictly view-only.

What Im happy with:

Any modern browser works as the viewer (Android, iOS, another PC), with pinch-zoom, panning and fullscreen.
Two capture modes: a screen copy, or PrintWindow, which keeps streaming the window even when other windows cover it.
Light on resources: a frame is encoded only when the picture has changed, and JPEG encoding goes through libjpeg-turbo.
Starts with Windows and finds the window again even if its title changes.
English and Russian interface, a single-exe build, unit tests, and user manuals in three languages. Python, MIT licensed.

One caveat: there is no password or encryption, so its meant for trusted networks only, and the docs say so clearly.

Code, a release with the ready-made exe, and documentation: https://github.com/eugenyh/WindowStream

Feedback and ideas are very welcome!

🚀 VoxShare – Multicast Push-to-Talk Audio App with GUI (Python)

Hi everyone! 👋

I've created an open-source desktop app called VoxShare — a Push-to-Talk voice communication tool that uses UDP Multicast and the Opus codec for fast and efficient audio streaming over local networks. It’s designed with simplicity and privacy in mind — no servers, no accounts, just instant LAN voice chat.

🎯 Key Features:
🔊 Real-time audio streaming with Opus codec (via PyOgg)
🌐 UDP Multicast — works without centralized servers
🖥️ Modern GUI built with CustomTkinter
🎤 Push-to-Talk (PTT) with optional keyboard shortcut
📻 Visual audio level meter
💡 Multiclient audio mixing (each peer is both sender and receiver)
🧩 Configurable INI file (with GUI options coming soon)
💬 Nicknames and active speaker display
🆓 100% open-source, cross-platform (Windows for now, Linux support in progress)

This project was born out of my personal need for a lightweight, LAN-based voice chat tool, especially for offline setups, local team coordination, or internal networks without access to Discord/Zoom/etc.

Any feedback, testing, suggestions — all are welcome! 🙌
Happy to answer any questions or collaborate with others.
