Hi I'm the author of Linen.dev. I can elaborate a bit on this. There are a ton of free tools that offer some form or another of this service. About half of the communities that are using Linen have built something similar themselves. We offer a bunch of little things that you might not build but are very helpful: * We support real time message sync in addition to historic uploads * We support sitemaps for large communities since our largest community has over 50k members and almost a million messages and it makes it easier for google to find the conversations * We support emoji and image attachments * We offer anonymization for your community members so it hides display name as well as profile pictures. We charge a higher price for premium account because we are 2 full time engineers working on this and want to hit profitability so we can be around for the long run. We are still experimenting with the pricing model so if pricing is an issue let me know.
