Xerahs

Windows macOS Linux Available

Xerahs is the most advanced screen capture tool for Windows, macOS, and Linux — ShareX reimagined with modern UI technologies, built from the ground up for cross-platform performance. Because it is ShareX-compatible, XBackBone configures it with the exact same custom-uploader file: one download and you are sharing straight to your instance.

Set up

1. Sign in to your XBackBone instance.
2. Open Integrations from your profile menu.
3. On the Xerahs card, click Download config to get your personal .sxcu custom-uploader file.
4. Import the .sxcu into Xerahs — it reads ShareX custom-uploader files — then select XBackBone as your active uploader.

That's it. Capture a screenshot or drop a file onto Xerahs and it uploads to your instance, copying the share link straight to your clipboard.

What the config contains

The generated .sxcu is a standard ShareX custom uploader, pre-filled with your instance URL and a personal API token. It targets the /api/v1/upload endpoint and is wired up as your image, text and file uploader as well as a URL shortener / sharing service, so every destination type flows through XBackBone.

On download, XBackBone mints a token granted the resource:upload and resource:deleteabilities — enough to upload new resources and remove ones you created (through the per-upload deletion URL).

Same config as ShareX

Xerahs and ShareX share the exact same custom-uploader format. A config downloaded from either card works in both apps — the only difference is the name of the token it issues, so you can tell them apart under Profile → Tokens.

Keep your token safe

The .sxcu file embeds an API token in plain text. Treat it like a password. If it leaks, revoke the token from Profile → Tokens and download a fresh config.

Troubleshooting

• Uploads fail with a 401 / "Unauthenticated". The embedded token was revoked or the config is stale — download a fresh .sxcu from Integrations and re-import it.
• Links point to the wrong host. Re-download the config after changing your instance's APP_URL; the URL is baked into the uploader at generation time.
