I did some research on the topic and focused on minimizing the cost per member (we are only a group of 5), simple UI, and having a searchable archive for all emails and having all the attachments indexed in an archive. I settled on https://gaggle.email/ It is not the most fully featured, there is one that allowed to tag discussions that seemed very appealing, but out of budget. The other ones I found are:. - Source: Hacker News / 3 months ago

Check if your country has public-funded LISTSERV/Mailman/etc. If not, I'll check https://gaggle.email. - Source: Hacker News / over 1 year ago

So, for the next readers, I found a way, even if not the prettiest one : using gaggle.email. Source: over 1 year ago

We have a lot of issues specifically with Gmail having significant delays with delivery that were looked at by others in the role before me. Ultimately we want to get rid of Listserv as even their cloud option isn’t cheap. Are there any good alternatives out there others have used? I found Gaggle Mail, which sounds like a good potential replacement but I need to research it further. Source: over 1 year ago

That argument would hold more power if there wasn't an existing native client for Slack and Discord, made by one person, with all the features I needed, working with absolutely no lag and minimal resource use, working on MacOS, Linux, Windows. Unfortunately the development stopped, or I'd still use it. https://cancel.fm/ripcord/. - Source: Hacker News / 5 months ago

Https://cancel.fm/ripcord/ Used it before, worked OK. Now I use Matrix, so I don't need it anymore. Neat trick: AppImages are squashfs compressed filesystems, so they can have slow startup etc. Fix this with ./app.AppImage --appimage-extract, find the binary in the created folder and run that one instead, so that you pay the decompression cost only once. - Source: Hacker News / 6 months ago

Not sure if it still works (or will continue to work) but this might be what you're looking for: https://cancel.fm/ripcord/ I've also had fairly good results using gtkcord4, though it takes it little finagling to get up-and-running: https://github.com/diamondburned/gtkcord4. - Source: Hacker News / 6 months ago

There are a bunch of features in slack beyond the core chat stuff, like: 1. Being connected to multiple communities and switching between them instantly this can be of course simply replaced by connecting to different servers in a tabbed terminal and use the terminal's built-in cmd-1/2/... shortcut, which happens to be the same as in slack. 2. Meta data about others, like their timezone or how to pronounce their... - Source: Hacker News / 12 months ago

All three of these are web browsers (slack and vscode are built on electron) that are notoriously RAM-hungry. If you don't want to buy new hardware, switching to using the slack web-app or using a third party client like Ripcord will remove one of those browsers, and using an IDE that isn't a web browser would take out another. You may also find that another browser like Firefox uses less memory than Chrome. Source: about 1 year ago
