GitHub - SnapXL/SnapX: SnapX is a free, open-source, cross-platform tool that lets you capture or record any area of your screen and instantly share it with a single keypress. Upload images, videos, text, and more to multiple supported destinations

Built on the foundations of ShareX, made cross-platform.

Everything you love, engineered for speed. User-centric. Native. Powerful.

Caution

SnapX is in Early Access. The core capture and upload engine is stable and ready for daily use. However, the Image Editor is still in the works.

Feature-wise

Supporting high DPI screens
Screenshots on an HDR monitor aren't blown out[1]
Cross-platform OCR powered by PaddleOCR for industry-leading precision. Experience accuracy that outperforms PowerToys OCR, ShareX, Tesseract, and Windows' built in OCR.

[1] When tested on KDE Plasma Wayland 6.2.90 with HDR, the resulting screenshots' colors were not blown out. Your mileage may vary.

Supported Desktop Environments

This application relies on XDG portals to handle screenshots in a secure and desktop-agnostic way. It is actively tested on:

We also use direct X11 screenshot capture on X based environments.

Tip

Other desktop environments or Wayland compositors, like Budgie, Cinnamon, MATE, Hyprland, and any others that have the right screenshot portal, should work, but they haven't been officially tested.

Packaging

See our quick start testing guide here to learn how to test SnapX.

SnapX is packaged on:

Flatpak (Flathub pending)

x86_64: Download
aarch64: Download

Additionally, you can download nightly builds from here.

Technical Details

Uses .NET 10 and ImageSharp (cross-platform image library).
Uses SQLite for image metadata like image hashes & history.
Uses YAML for a cleaner configuration supporting comments with auto migration from JSON.
UI is GPU-accelerated, leading to a more responsive UI & yet less CPU usage while navigating the UI. (Fixes low performance on 4K screens with a weak CPU)
Respects XDG directory specification, Symlinks ~/Documents/SnapX to respective config/data directory on Linux/macOS.
Uses Direct3D11 & WinRT to capture on Windows, XCap on macOS, and XDG Portals on Linux.
Supports PNG (including animated variant), WEBP (including animated variant), AVIF, JPEG, GIFs (should be smaller than your typical ShareX GIF), TIFF, and BMP image formats.
Supports 95% of ShareX uploaders (we're a fork!).
Allows you to fully configure SnapX via the Command Line via command flags & environment variables. Additionally, you can configure SnapX using the Windows Registry.
Keeps compatibility with the custom uploader configuration format (.sxcu).
As a user, you do NOT need to have .NET installed. Whether you're on Linux, Windows, macOS, or FreeBSD.

What does this all mean? It means you'll be able to have a more performant, reliable, and stylish application.

You will not receive any support from the ShareX project for this software.
