HOW IT WORKS
·
A code for your folder. That’s it.
Nothing uploads. The folder stays on your drive. The other side opens Foldy, types the code, and gets a live view through a direct WebRTC tunnel between your machines.
02
CODE
Get a code.
Foldy hands you a short code, easy to read aloud. Paste it in chat, dictate it on a call, write it on a sticky note.
EXPIRES ON CLOSE
03
OPEN
Open it on another device.
The other side runs Foldy, types the code, and sees the folder live — read, write, drag, delete. Like a network drive that exists for one conversation.

WHO IT’S FOR
·
Built for anyone who keeps things on their own drive.
Personal use.
Your photo archive on the desktop. Mounted live on your laptop and your phone. No iCloud bill, no upload wait, no compressed thumbnails — the originals, on demand.
ONE PERSON · MANY DEVICES
Distributed teams.
Drop the project folder in. Six engineers in three time zones see it live. No per-seat fees, no admin console, no waiting for sync — the folder is just open while you’re online.
SHARE ONCE · LIVE FOR EVERYONE
Big families.
The household photo archive lives on the home Mac. Grandma sees it on her tablet. The kids dump school stuff from their phones. One drive, the whole family — no rented terabyte.
ONE HOUSEHOLD · ZERO RENT
TRY IT
·
Three seconds. No upload.
Pretend this is your machine. Drag the folder onto the share zone and watch the rest of it happen — same flow as the real app, nothing leaves this page.

WHY NOT CLOUD
·
Every cloud quietly does three things. Foldy does none.
We don’t host your files.
Once a cloud has your bytes, they live on its disks — its TOS, its subpoenas, its training set, its next price hike. Foldy never touches them. The folder stays on your laptop, with you.
DIRECT P2P · NO MIDDLE
We don’t read your files.
Clouds need to read your files to “optimize”, “scan”, and improve their model. We’re not in the loop — the connection is end-to-end between two machines. No middle, nothing to read.
END-TO-END · ZERO KNOWLEDGE
We don’t hold your files hostage.
Cancel any time. Because your files never lived on our servers, there’s nothing for us to delete, lock, or hold for ransom. Your folder stays on your drive — subscription or not.

Same folder. Now in your pocket.
Open a folder on your Mac. Hold up your phone. Scan the QR. The same folder mounts live on Android over WebRTC — read, write, gallery-integrated. Same Ed25519 identity, no cloud in the middle.
PAIRING
QR quick-pair.
Point the phone at the laptop. The same Ed25519 identity carries across — no re-typing, no re-trusting.
MOUNT
Live folder mount.
Bytes stay on the laptop. The phone reads on demand. First paint lands in a couple hundred milliseconds, even on a big folder.
RESUME
7.5-minute retry.
Network drops mid-transfer? StatPartial picks up where it left off. Outlives a full WebRTC rebuild.
GALLERY
Gallery integration.
Swipe through a photo folder like it’s on the device. Multi-select, share-sheet, bulk move — straight from the laptop.
FAQ
·
Quick answers.
01 Where do my files actually live?
On your machine. Foldy doesn’t have a server full of your folders — it opens a direct connection between you and the person you’re sharing with. If you close your laptop, the share goes offline. When you open it again, it comes back.
02 Is it encrypted?
Yes. Every byte between the two devices is end-to-end encrypted over WebRTC’s DTLS-SRTP, keyed by an Ed25519 identity that lives on the device. Keys never leave your machine. Foldy can’t read your files even if we wanted to — the cipher is
ChaCha20-Poly1305 and the trust model is TOFU, like SSH.
03 What happens when my computer is offline?
The share is paused. The recipient sees “sender is offline” until you come back online. There’s no “cached copy in the cloud” — that’s the whole point. Your folder, your machine, your availability.

04 Do I need an account?
Yes — your email signup IS your account. We use it to keep your shares organized, recognize you across devices, and get you onto the beta. No password chase, no “verify your email” loop — just the email you give us above.
05 Is there a file size limit?
No artificial cap. The practical limit is the slower of the two internet connections and how much RAM you want a single transfer to use. Big folders just take longer to read file-by-file on demand — the same way they’d download from any source.
06 Can I share with multiple people at once?
Yes — you can attach multiple recipient devices to the same share. Paid plans differ by how many devices you can attach.
07 How will Foldy be priced?
Foldy will have paid plans, priced by the number of recipient devices on your share. Exact tiers are still being finalized — beta sign-ups get locked-in early pricing.
08 How is this different from Dropbox / WeTransfer / iCloud?
Those copy your files to their servers first. We don’t. Dropbox is a synchronized clone, WeTransfer is a temporary upload, iCloud is rented storage. Foldy is none of those — it’s a live window onto a folder that already exists on your drive.
09 What about Nextcloud or Syncthing?
Nextcloud is our closest cousin in spirit — same anti-cloud instinct. But the lift is real: you run a server, pick a host, install, configure clients, route a domain, keep it patched. And the files still copy through your box. Syncthing is genuinely peer-to-peer, no middle, but it’s sync — full mirrored copies on every device, configured ahead of time, running in the background. Foldy skips both shapes. It’s a live mount: nothing copies, the folder appears on the other side only while the share is open, set up with one short code.
10 Is beta open?
Beta is open. You can sign up above and start using Foldy now — we’re still adding people in waves to keep peer-discovery healthy, but the gate has moved from “wait for invite” to “you’re in.”
