I don't know if these are multi-tenant projects but you could certainly explore them: leantime.io and openproject.org. Source: about 1 year ago

I just started messing with OpenProjectOpenProject which seems pretty nice, but I actually bought a lifetime license to Nifty.pm a couple years ago on AppSumo and it is awesome.. Not free or open source or self-hostable though.. :/. Source: over 1 year ago

Openproject.org BIM edition is the closest I got so far, but it lacks the smooth versioning experience of git and the accessibility of a platform like github. Source: almost 2 years ago

I know I am asking for a lot here. I worked for a company that used everything from Atlassian and miss the unified experience. Now I am working for a hospital and we are required by law to keep everything on premise. Atlassian makes it very obvious that they are a "go cloud or gtfo" company so... I am kind of searching or something equivalent. Currently using openproject.org as a JIRA replacement, Mediawiki as a... Source: almost 3 years 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 / 5 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 / 5 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 / 11 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
