I’m in the process of rebranding and moving domains, so the documentation links are broken. You can try the search. it seems to work reasonably well. A good place to start could be from here:

Feel free to reach out for clarity on anything.

Thanks!

Here is the foss equivalent of this project: https://github.com/positive-intentions/chat

Unfortunately, open source isn’t sustainable. I’m investigating close-source as a way to create something competitive. My plan is to try to sell it on the Play store.

As for pairdrop, their approach to peer discovery relies on knowing the network you’re connected to. This makes it easy to find peers in cases where you use the same WiFi network. In mine I’m using WebRTC to allow connections over the internet. Peer discovery is achieved by using crypto-random IDs exchanged as a link or QR code.

Ultimately it’s worth noting my app is a work in progress and not ready to replace existing apps or services. I hope I can update the UX to make the functionality as seamless as pairdrop.

This is using the WebRTC protocol. As a webapp it’s immediately good to go, there isn’t a need to run something like a FTP server.

Of course limitations apply like sending larger files nukes my ram… But I after it’s sent, it seems to settle down.

I have a weird setup with open and closed source.

I have open source examples of this code in action. If interested: https://github.com/positive-intentions/chat

I’m trying to keep it vanilla. I’m using module federation (love it or hate it), to get it from this repo.

Thanks!

Perhaps you’d like to give feedback on a separate but similar foss project: https://github.com/positive-intentions/chat
