Have a great idea for your new startup? Let’s get acquainted with the most appropriate technologies of the backend. The most common and widely used backend technologies are web programming languages Ruby, Python, PHP, and NodeJS. Each of them must be paired with the right frameworks, libraries, and runtime environments to ensure success. At Async Labs, our primary backend technologies are PHP and NodeJS, but we are open to other technologies, so we have systems in C #, Python, and Ruby.
