AirLynk
Airlynk — browser peer-to-peer file sharing without servers
I built Airlynk because I was frustrated with every peer-to-peer file sharing tool I tried — connections would fail, transfers would stall, and NATs or firewalls always got in the way. Nothing I tested was reliable enough for real use, and I wanted a solution that actually worked.
So I decided to build it myself. Over several months, I crafted Airlynk to work entirely in the browser, using WebRTC for direct peer-to-peer transfers. I designed it to be simple, fast, and server-free, with fallback relays only when absolutely necessary. Chunked transfers and progress tracking make even large files move smoothly.
The journey taught me a lot about peer-to-peer networking, browser limitations, and user experience. My goal with Airlynk is to make file sharing effortless for everyone, and I’m excited to keep improving reliability and security based on real feedback from users.

Oh...when I visited your site a minute ago on my phone it told me "Your device and data are at risk. Viruses have been detected on your device!
For the safety of your device and stored data, do not.." and then it did all that fake file scanning stuff and wanted me to install McAfee.
I didn't, obvs.
Love the idea of your product though.
Love this. Peer-to-peer in the browser without servers is insanely ambitious — especially with all the NAT/firewall headaches.
The fact that you actually got it working reliably is huge.
As a solo founder building an AI ops copilot (Kaelis), I really resonate with the ‘build what you couldn’t find’ mindset.
Respect for tackling something so technical and user-centric 👏
Looks great. I use Tailscale for this but it's a slightly different use case as you install the TailScale client on all devices on your own private network.
They have some clever solutions for NAT traversal.

Thanks! Yeah, Tailscale’s approach to NAT traversal is really smart — we took a lighter, browser-based route so users can share files instantly without any setup or client install.
That's awesome, I have found myself using mediafire or mega to transfer files between 2 pcs on way too many occasions. This is incredibly useful in those cases. Any plans on making a browser extension out of it?
Thanks a lot! I’m really glad you find it useful 😊
A browser extension is actually something I’ve been considering, and I’ll definitely be working on it soon — it should make file transfers even more seamless between devices.
