A lightweight Linux alternative to Parsec for UDP screen streaming & real-time latency telemetry inspired by Parsec workflows. Disclaimer: This project is an independent open-source tool and is not affiliated with, sponsored by, or endorsed by Parsec Cloud, Inc. or Unity Technologies. Uses CPU JPEG frame encoding over UDP rather than proprietary GPU hardware codecs.
Key capabilities: • UDP Chunked Frame Streamer (Host & Client): captures X11 desktop frames via QScreen.grabWindow, encodes JPEG at configurable FPS (10-60), scale (50%-100%), and quality (30-95), splits frames into numbered UDP datagram chunks with microsecond timestamps, and reassembles frames in real time. • UDP Input Back-Channel: forwards mouse movement, clicks, scroll wheel, and keyboard events over UDP; applies input on X11 via XTest (libXtst) when available, or runs in honest view-only mode otherwise. • Live Real-Time Telemetry & Graphs: measures round-trip latency (RTT ms) via UDP timestamp echo, RFC 3550 EWMA jitter (ms), packet/chunk loss (%), measured FPS, and bitrate (Mbps) on live QPainter sparklines + frame log. • Stream Presets, Peer Access Control & Diagnostics: LAN High Quality / Balanced / Low-Bandwidth presets, HMAC peer token allowlist & session log, and a built-in localhost UDP loopback benchmark.
Honest limitations: direct UDP only (no cloud relay or NAT traversal; host UDP port must be reachable on LAN/VPN). Uses CPU JPEG frame encoding rather than GPU hardware H.264/HEVC codecs, does not stream audio, and cannot access Wayland-native compositor windows or root lock screens.

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
Snap can be installed from the command line on openSUSE Leap 15.x and Tumbleweed.
You need first add the snappy repository from the terminal. Choose the appropriate command depending on your installed openSUSE flavor.
Tumbleweed:
sudo zypper addrepo --refresh https://download.opensuse.org/repositories/system:/snappy/openSUSE_Tumbleweed snappy
Leap 15.x:
sudo zypper addrepo --refresh https://download.opensuse.org/repositories/system:/snappy/openSUSE_Leap_15.6 snappy
If needed, Swap out openSUSE_Leap_15. for, openSUSE_Leap_16.0 if you’re using a different version of openSUSE.
With the repository added, import its GPG key:
sudo zypper --gpg-auto-import-keys refresh
Finally, upgrade the package cache to include the new snappy repository:
sudo zypper dup --from snappy
Snap can now be installed with the following:
sudo zypper install snapd
You then need to either reboot, logout/login or source /etc/profile to have /snap/bin added to PATH.
Additionally, enable and start both the snapd and the snapd.apparmor services with the following commands:
sudo systemctl enable --now snapd
sudo systemctl enable --now snapd.apparmor
To install Low Latency Screen Stream, simply use the following command:
sudo snap install low-latency-screen-stream
Browse and find snaps from the convenience of your desktop using the snap store snap.
