Matching the technology to the hosting.
WHAT RUNS EASILY ON SHARED HOSTING
PHP applications of any kind: WordPress, Laravel, custom code. This is what shared hosting is built around, and everything works without special arrangement.
Static sites, which run anywhere.
WHAT RUNS WITH SOME CONSTRAINTS
Node.js and Python applications, where the interface is available, within the limits described.
WHAT NEEDS A VPS
Anything requiring persistent processes, websockets, custom system packages, specific service versions, or root access.
A PRACTICAL POINT
The stack you know beats the stack that is fashionable. A well-built PHP application on shared hosting serves users better than a poorly understood modern stack on infrastructure you cannot maintain.
BEFORE COMMITTING
If you are choosing technology for a project that will live on shared hosting, confirm it runs there before you build. Discovering the constraint after three months of development is expensive.
Open a Sales ticket describing the intended stack and we will tell you what is possible.
