Hey Product Hunt! 👋 I built AnyDrop out of pure personal frustration. Recently, I was doing some cross-platform troubleshooting on a borrowed Windows laptop. I quickly realized that while moving files between a Mac and a PC is annoying, moving a simple block of text, a syntax snippet, or a long URL is infinitely worse. I was tired of emailing myself code snippets or logging into messaging apps just to copy and paste one line of text. So, I built a universal, browser-based alternative to AirDrop that requires absolutely zero friction to use. Here is what AnyDrop does: Live Notepad & Clipboard Sync: Open a shared notepad between connected devices to instantly paste code snippets, links, or text blocks back and forth in real time. Frictionless File Drops: Drag and drop files of any size seamlessly across Mac, Windows, iOS, and Android. Auto-Discovery: Just open the site on two devices on the same Wi-Fi, and they find each other instantly. If you are on different networks, use a Magic Link or QR code to pair them. Secure Chat & Voice Notes: Tap on a connected device to open an end-to-end encrypted chat thread directly between the screens. The Tech & Privacy: Under the hood, AnyDrop uses WebRTC for direct Peer-to-Peer (P2P) transfers. This means your files, chat logs, and clipboard snippets are never uploaded to a database or cloud server. Everything travels through an encrypted tunnel straight from Device A to Device B, and the exact moment you close the browser tab, the session is permanently wiped. It's 100% free, there are no ads, and you don't need to make an account. I am actively optimizing it, so I’d love for you to test out the real-time notepad sync and see how fast you can push large files. Let me know if you run into any bugs or have feature requests!

I have been asked many times on the privacy part of the. Under the hood, AnyDrop is built entirely on WebRTC Data Channels. To keep it secure and cloud-free, here is how the flow works:

First, our server strictly acts as a switchboard using WebSockets. It just helps the two devices find each other to trade connection info. Once that handshake is made, our server steps completely out of the way.

From there, it’s true peer-to-peer. The file bytes flow directly from Device A to Device B, meaning your files literally never touch our servers. Because it’s built on WebRTC, that direct connection is automatically end-to-end encrypted (DTLS/SRTP), so even if you're on a public Wi-Fi network, the transfer is completely locked down.

Finally, to guarantee a zero digital footprint, the incoming file chunks are buffered directly into the receiver's temporary browser memory (RAM). When the transfer finishes and you click download, the browser saves it straight to your local drive. No databases, no cloud uploads, and no lingering files!

Let me know if you want to dive deeper into the tech stack, always happy to geek out about it!

As someone using an Android phone alongside a Mac, this is exactly the gap I've felt for a long time. AirDrop is great until it isn't, and most workarounds feel like overkill. The fact that it works just from a browser with no account is what makes it actually usable. Congrats on the launch!

@ray_artlas Thank you for your kind words.

Congrats on the launch.

Japan-based founder here. One Japan-specific thought: the “AirDrop in your browser” idea is clear, but Japan already has strong sharing habits around AirDrop, LINE, and Google Drive.

The sharper local wedge may be temporary no-login sharing in events, schools, clinics, small teams, or cross-device troubleshooting, where “no cloud / no install” matters more than generic file transfer.

@wakuta Thank you for your thoughts. The idea for AnyDrop is that you don't always want to swap personal chat handles or mess around with Google Drive access requests just to share a quick reference file or document.

The idea is that everyone just leaves an AnyDrop tab open. It turns into an instant, temporary drop zone where anyone on a Mac, PC, or phone can bounce files back and forth and also use chat to send text snippets easily. The app support any number of devices at the same time. Easier alternate where you don't need any accounts, no giving out your personal info, and everything stays completely private.

@jamshic That makes sense. Framing it as an instant temporary drop zone is clearer than “file transfer.”

For Japan, I’d probably test 3 concrete use cases first:

1. small in-person events / meetups where people do not want to exchange LINE or Google Drive access,

2. clinics / small offices where temporary document sharing needs to feel private and accountless,

3. cross-device troubleshooting between family members or small teams.

The “no accounts, no personal info, no cloud” part may be the strongest local trust angle.
