DoubleSpace gives you Dropbox convenience on infrastructure you own. Unlike rclone, it works out of the box. Unlike Dropbox, your files go to your own R2 bucket.
Install
Download the desktop app or CLI. Run dblspc setup — it auto-creates your R2 bucket on Cloudflare.
Sync
Pick folders to sync. DoubleSpace watches for changes and pushes them to R2 in real time. Pull changes from other devices automatically.
Mount
Mount your cloud storage as a native drive letter. Open it in File Explorer, Finder, or your file manager. Read and write like a local disk.

Your storage. Your rules.
DoubleSpace never touches your files. The CLI and desktop app sync directly to your Cloudflare R2 bucket using your own S3 credentials. Our API handles auth, metadata, and sync coordination — that's it. No proxy. No middleman. R2's first 10 GB are free.
Continuous Sync
WebSocket push keeps every connected device in lockstep. Edit a file on your laptop — it appears on your desktop in seconds. Offline? Changes reconcile on reconnect.
Native Drive Mount
Mount as a Windows drive letter (D:), macOS Finder volume, or Linux FUSE path. No browser needed. Files appear in your OS like any local disk.
Zero Egress
Cloudflare R2 charges $0 for downloads. Sync, share, and download your own files without bandwidth fees. Multipart uploads handle files up to 5 GB.
AI File Agent
Ask questions about your files in natural language. Semantic search finds documents by meaning, not just filename. Auto-tag and organize with Workers AI.
Share Links
Generate public links with password protection, expiration, and download limits. Recipients access files without creating an account.
Full-text Search
FTS5-powered content search. Text extracted and indexed on upload. Find any file by name or by what's inside it.
