Which tech when?

02 Aug 2026

Question to ask when starts a project:

Does it needs to serve a lot of user or a few single user?
Does it needs to keep a lot of long-lived connection?
Does it needs to process a lot of request per second?
Does it needs high fault-tolerance and scaling?
Does it optimize for concurrency or for speed?

In my opinion:

Zig, Rust, C, Go

Embedded system
Small and fast single user app
Reliable process
A lot of HTTP request per second
SPEEEDDDD

Elixir

Massive concurrency
Chat systems
Real-time related stuff like dashboard, messaging, collaborative app

Python

Just for experimenting and trial
Should never build real system with it
