I'd give https://papercups.io a try, they have a native flutter chat widget (last I checked the only live support native flutter package). Source: over 1 year ago

HelpKit does have a widget that you can embed on your own site. HelpKit itself has a built in email contact integration. If you want a live chat widget with HelpKit, the widget allows you to hook up one of many live chat providers… One of them called Papercups is actually fully free to use such as Tawk + more privacy friendly :).

If chat means just "customer should be able to chat directly with our employees" for you, then something like chatwoot or papercups should do the job. Basically just a chat widget you can drop into your site where customers can message you. Source: about 2 years ago

No affiliation, but have you looked at https://papercups.io/ ? They are also OSS: https://github.com/papercups-io/papercups. - Source: Hacker News / over 2 years ago

Yeah, it's kinda crazy. I'm considering just inhousing to https://papercups.io/ and save a bunch of money each month. Source: almost 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
