GNOME Remote Desktop vs Jubler

GNOME Remote Desktop is GNOME's free, open-source remote desktop server for Linux. It supports remote assistance to an active session, single-user headless desktop access, and headless remote login. The server offers RDP and VNC backends, though they do not support every operating mode equally. Locking the screen ends a remote-assistance connection; multi-user headless remote login integrates with GNOME Display Manager and is available only over RDP. PipeWire streams pixel content, libei handles input events, and Mutter's remote desktop API manages sessions. RDP uses FreeRDP and requires a TLS key and certificate; VNC uses LibVNCServer and supports password or prompt authentication. GNOME Settings can show an encryption fingerprint for comparison with the client. GNOME 50 adds Vulkan and VA-API hardware acceleration, HiDPI scaling, camera redirection, Kerberos authentication for screen sharing or single-user headless servers, and support for remote login sessions launched with gnome-headless-session. Listed working clients include Remmina, Connections, and xfreerdp on Linux, mstsc on Windows, and Thincast on Linux, Windows, or macOS. The project cautions against opening the firewall to the public internet.

Jubler is a free, open-source desktop editor for creating, revising and converting text-based subtitles. It runs on Linux, macOS and Windows and handles more than 20 subtitle formats, including SRT, ASS/SSA, WebVTT, TTML, ITT, DFXP and YouTube subtitles. Users can shift timing, convert frame rates, split or join entries and files, check spelling, and search and replace with regular expressions. A timeline with draggable subtitle blocks supports two-point synchronization. With VLC, Jubler can preview video and frames, show audio waveforms and let users edit subtitles during playback. Quality tools include configurable validation rules and TED guidelines checks. Translation mode supports Azure Translator, and command-line tools are available for batch work and automation. Downloads include builds for Apple Silicon and Intel Macs, Windows, Linux x86_64 and arm64, as well as a generic Java version. VLC is required for video preview and audio waveforms; ASpell is suggested for spell checking. Jubler is licensed under AGPL-3.0.
