Why Swarm
No servers. Just Swarm.
Nook runs a Swarm node on your computer, so your files live on the Swarm network, not in someone's data center.
-
No company in the middle
Independent nodes hold your files, not one company.
-
Upload and walk away
Your files stay online when your computer is off.
-
Can't be swapped
Whoever opens your link gets exactly what you uploaded.
-
Outlives the app
Any Swarm app can open your files, not just Nook.

How it works
Where your files actually go.
Nook keeps your files on Swarm: a network of independent nodes, not one company’s servers.
-
Split
Your file is cut into small chunks of 4 KB, each with its own address, and the whole file gets one address you can share.
-
Upload
The chunks are spread across the nodes of the Swarm network. Each chunk is kept by several nodes, so one going offline loses nothing.
-
Store
You pay upfront for as long as you want to keep it, and node operators get paid to hold on to your chunks. Close your laptop; your file stays online.
-
Download
Your node asks the network for each chunk. The request is passed from node to node until it reaches one that holds it, and the chunks come back and rebuild the file.
What you can do
Everything in one quiet app.
Create drives that auto-extend
Choose how much space you need and for how long. Turn on auto-extend to keep the drive alive. Nook notifies you before it extends, and if your funds are running low.
Deletable drives
Delete files from a drive and get the space back for new ones. Useful for content that changes over time. Currently in beta.
Share privately
Encrypted drives you can share with the people you choose — and revoke access again whenever you want.
Publish a website
Drop in a folder and it's live — with a permanent address that stays the same when you update, and your ENS name.
End-to-end encrypted messages
Message other Nook users. Encrypted on your device, stored on Swarm, readable only by the two of you.
FAQ
Good to know.
What does it cost?
Nook itself is free. Storage on Swarm is paid upfront in xBZZ for a size and a length of time you choose — no monthly subscription. Small amounts of xDAI cover network fees.
What is Swarm?
Swarm is a decentralized storage and communication network. Files are split into chunks and kept by many independent nodes, so no single company holds your data.
What is Swarm ID?
Swarm ID is a decentralized identity for apps built on Swarm: one account you create and manage yourself, and use to sign in across Swarm apps. You sign in with a passkey, an Ethereum wallet or a password. Every key comes from your account's recovery phrase, each app gets its own keys so two apps never share one, and your account can be restored from Swarm on a new device. In Nook, Swarm ID is how other Nook users find and message you. Keep your recovery phrase safe: it's the only way back into your account.
Is it ready for everyday use?
Nook is in beta. It works, and we use it daily — but features change and bugs happen. Keep only small amounts in the node's wallet.
Which computers does it run on?
macOS (Apple silicon and Intel), Windows and Linux (.deb and .rpm).
