saltboZPan
The open-source, S3-native file hosting platform.
Image bed, file sharing, and backup — powered by S3, deployed anywhere.
What is ZPan?
ZPan is a lightweight file hosting platform built on top of S3-compatible storage. Files upload directly from the client to S3, bypassing server bandwidth entirely.
Three scenarios, one platform:
- Image Bed — Upload via PicGo / ShareX / API, get a URL instantly
- File Sharing — Upload files, generate share links, distribute to anyone
- File Backup — CLI agent syncs local directories to S3/R2
Deploy
Cloudflare Workers (Recommended)
Deploy via GitHub Actions with zero server management. Free tier covers personal use.
- Fork this repository
- In your fork, go to Settings → Secrets and variables → Actions and add:
CLOUDFLARE_ACCOUNT_ID— found on the Cloudflare dashboard sidebarCLOUDFLARE_API_TOKEN— create one here with Workers Scripts:Edit and D1:Edit permissions
- Go to the Actions tab, select Deploy to Cloudflare Workers, and click Run workflow
After initial setup, the workflow runs automatically every time you sync your fork with the latest release.
Docker
Quick start — pull the pre-built image:
curl -O https://raw.githubusercontent.com/saltbo/zpan/master/deploy/docker-compose.yml
docker compose up -d
With RustFS (self-hosted S3-compatible storage):
curl -O https://raw.githubusercontent.com/saltbo/zpan/master/deploy/docker-compose.rustfs.yml
docker compose -f docker-compose.rustfs.yml up -d
RustFS console will be at http://localhost:9001 (admin / admin123). Create a bucket there, then configure the storage in ZPan's admin panel.
