Please have a look at the warnings in the comments:
Meshcentral is discontinued because it was based on Intel ME (official program completely sucks) and when the dev was fired by Intel, he obviously lost any interest in the thing. All downloads even removed, only the source is available
Completely disagree. Meshcentral is amazing. I use it almost everyday. Sure it has some querks, and I am not a fan of the default layout but that is an easy change.
It is certainly not discontinued.
Yes Ylian (the developer) was laid off from Intel and later started working at Microsoft. But the project is still alive and well. (He owns the domain so he was able to keep the website alive. Another user (Si458) Has taken up alot of the development (30 commits this month ) and Ylian has also continued development although much less now he has a day job. (1 Commit this month)
The only thing that got discontinued was the publicly hosted server of MC. That was costing to much and it required to much maintenance now this became a side project. So you will need to self host it now.
I was searching for a binary 6 months ago and they were all removed. The website is still offline
You can download everything here. https://meshcentral.com/downloads.html
But to your point https://www.meshcentral.com (That is linked in the Github page give me a certificate error. Guess they need to fix that lol) But https://meshcentral.com (without the www) works.
Github page has been fixed!
