Mattermost VS mattermost-webapp

> Tell me another platform that is free, has realtime chat, voice and video, has stable service, allows sharing images and other media, with good ownership management... and is open source.

Mattermost: https://mattermost.com/

Rocket.Chat: https://www.rocket.chat/

Nextcloud Talk: https://nextcloud.com/talk/

Self hosting and some assembly required. I've run all of them on cheap VPSes to explore a Slack/Discord replacement, neither was mindblowing but all of them seemed okay (Nextcloud's offering was rather barebones, though).

Audio and video support varies because getting those right is challenging, at best you'd just integrate with something like Jitsi, that one's actually pretty good for meetings and such: https://jitsi.org/ and has a cloud version too: https://meet.jit.si/ (yet people still go for Zoom and it's odd UI/UX choices)

I actually rather liked forums back in the day, but I guess nobody will be setting up that many phpBB instances in the current year, though projects like Discourse also seem promising: https://www.discourse.org/

I don't think many people at all will be leaving Discord, due to how entrenched the platform is (network effect): if you want people to help you with what you're working on, you go where they are, not vice versa.

Mattermost for Chat, and also for Notifications sent by Uptime-Kuma

Mattermost offers a secure, open-source solution for seamless collaboration throughout the software development lifecycle. Tailored to cater to technical and operational needs, it easily integrates with a wide range of third-party developer tools—to streamline development and engineering workflows. With self-hosted and private cloud deployment options, coupled with access to the source code, you have complete control over the data via a shared, adaptable, and extensible platform designed specifically for your team. Kindly suggested by Molasses_Major.

FWIW, most of the TypeScript lines of code are in the E2E tests[0] and the webapp dir [1], which, as the name suggests, contains "the client code for the Mattermost web app". So we should really only be counting lines of Go code.

Mattermost is an good alternative to companies, workers and teams.

But it seems that you're right for Mattermost.

I don't know about the quality, but Mattermost is in TS: https://github.com/mattermost/mattermost-webapp

On the web platform end, we merged the upgrade to React 17 (again) into master, and performed a bunch of (more minor) dependency updates while at it. We also continue our journey towards using MUI-based menus.

On the web platform end, we continue the work on menu components, found and fixed the issue that marked a whole lot of channels as unread last week (with GarphQL enabled). We’ve also been working on performance regression tests. And we’re upgrading moar dependencies.

On the web platform end, the team has been working on unifying post components (and cleaning up afterwards), more fighting with Webpack and friends in the context of the front-end part of the multi-product architecture, testing out a prototype of menus based on Material UI, and the regular cycle of dependency updates.

On the web platform end, beside being overwhelmed by anticipation of the upcoming new joiners, we’re making good progress in getting webpack federation ready to be merged. This will be a solid step towards the multi-product architecture on the front-end. The upgrade to React 17 is also almost there. Beyond that, as mentioned, we’re fixing a few issues in GraphQL before we enable it again on community.

On the web platform end, we are experimenting with “theme weeks” as a budgeting hack to work on important but not urgent stuff. This first theme week (and this will likely be a recurring one) is focused on 🥁 performance! We’re pulling in a whole bunch of tickets accumulated over time of smaller things we can optimize for performance. Some of these improvements are already landing.

Platform involves work in many of our “highest traffic” repositories. I’m still figuring out reasonable ways how to keep up with what’s happening in the webapp, server, mobile repos as well as everything related to QA.

Most projects on GitHub have CONTRIBUTING.md file which describes how you can contribute, so you can start from there. Generally I'd say getting to meaningful contributions is very difficult for someone without real-world development experience, so if you choose to do this it won't be easy. On the other hand, this is precisely why employers prefer people who already have this experience -- it takes time and effort and not everyone makes it even with support from senior collegues.

Mattermost was the closest I was able to find and until their cloud beta finishes you have to setup a server to run them. With a Github or Google identity you are one click away from running Uclusion (and with any email several clicks) - no credit card required.
