Chatlio offers this functionality pretty well from what I've seen. A workspace in my org uses them to respond to people who ask questions through their site's chat function. Source: about 2 years ago

Wow, awesome advice. Yeah, you're right. I will have to reconsider some stuff. I was initially modeling the pricing based on Chatlio. But I think you're right in a lot of ways. Source: over 2 years ago

Yes. https://chatlio.com/ Creates a short-lived channel per chat. It works well in terms of sharing responsibilities with a team and allowing people to jump in easily. I did feel a bit of unease with having customers in the same place as our "private" conversations. - Source: Hacker News / about 3 years ago

For file transfers over the internet, https://wormhole.app/ and https://toffeeshare.com/ are often suggested. - Source: Hacker News / 3 months ago

Isn’t https://wormhole.app/ the solution here? Note I haven’t used it, it’s just often brought up here as a good solution for this class of problem. Is it surprising that the author mentions a ton of solutions but not this one? - Source: Hacker News / 4 months ago

One of the two creators of https://wormhole.app here :) Now that we’ve shifted our company’s focus to https://socket.dev, I’d love to open source Wormhole. I’m quite proud of the code - I’ve worked on P2P and file transfer systems for so so long that I think this might be some of the best code I’ve worked on. It’s just a matter of finding the time, but I expect this will be open source eventually. - Source: Hacker News / 5 months ago

It's unfortunately not FOSS, but I quite like https://wormhole.app/ - It's client side encrypted and P2P when possible. - Source: Hacker News / 5 months ago
