Self-hosted personal cloud
The personal cloud
you actually own.
Cloud9 is self-hosted file storage with a signature drop-link: anyone can send you a file, no account required.
Your files stay under your control

Built for private, personal use
A link that lets anyone hand you a file.
Generate an unguessable URL and share it. Whoever opens it uploads straight to your inbox, tagged with a name, a message, and threaded comments.
- The sender needs no account and no app
- Set an expiry, password, size cap, and upload cap
- Bot checks and per-link rate limits keep abuse out
Three moves from empty link to file in hand.
Generate
Create a drop-link with an expiry, a size cap, and an optional password.
Share
Send the URL through chat, email, anywhere. The person on the other end needs nothing.
Receive
Their upload is held for a safety check, then lands in your inbox with full attribution.
Your files, your rules
A real file manager, not a folder of links.
Resumable by default
Large uploads survive a closed tab and pick up where they left off, with progress the whole way.
Trash, then restore
Deletes are soft. Recover a file or a whole folder tree from Trash.
50 GiB
Per-user quota by default, enforced at upload so the bill never runs away.
Anonymous uploads, treated as a threat until proven safe.
Letting strangers upload is a security minefield. Cloud9 is built for it from the ground up.
Sandboxed content
Uploaded files are served from a separate, locked-down surface, never alongside the app.
Real file checks
A .exe renamed to .png is rejected on sight, not by extension.
Safety first
Every drop upload is held for a check before it reaches your inbox.
Private downloads
Files are never left open to the public. Downloads use short-lived private links.
