Unfortunately, it is not possible to deliver Live Topics to a classic self-hosting environment. Our "cloud" is not simply "some server space" but rather a complex array of technologies wrapped up in custom configuration and code.
Live Topics is not a PHP and MySQL application. It is actually a React and NodeJS app and uses the following technologies: NodeJS via ExpressJS server, ReactJS, Web Sockets/Socket.io, JWT Authentication, Redis, AWS SQS, AWS EC2 and MySQL. Those technologies are managed via a custom SQS queue which triggers command runners and workers. All this is bespoke to our cloud environment.
Even if you managed to set up all those services, you'd still need our configuration and custom elements.
By developing on a single platform allows us to rapidly deploy new features and functionality.
This makes it unsuitable for a self-hosting environment.
