Ruby on Rails web framework uses the Ruby programming language for most of its web applications development tasks. On the other hand, Laravel is based on PHP (Hypertext Protocol) programming language for developing web applications that work across different operating system platforms.

Like every programming language has a syntax or format of inputting machine code for the purpose of creating websites and software programs that can be used by both tech-savvy and non-tech savvy individuals, the same goes with Ruby on Rails and Laravel as well. However, the difference here is that Laravel uses semi-colon and curly braces in their code, but this is not so in Ruby on Rails. RoR does not support the use of semi-colon and curly braces in their code.

The use of Ruby on Rails and Laravel differs as well. Ruby on Rails is basically a back-end web application development platform and meta-programming framework. On the other hand, Laravel web application development framework’s usage is predominant in enterprise-level application to building small websites.

The template engine used by Ruby is ERB (Embedded Ruby), which is a feature that enables developers to generate any kind of text and of any quantity conveniently from the templates. ERB is part of Ruby’s standard library. On the other hand, the template engine that is used by Laravel is Blade, which can also use PHP code directly in view.

ORM tool is used for automated management of database, where the user does not necessarily have to call the database, it is handled by the ORM. Ruby on Rails uses Active Record as its ORM tool for database management. Laravel, on the other hand, uses Eloquent as its ORM tool for database management tasks.

Resources are needed to run the web framework. Thus, both Ruby on Rails and Laravel web frameworks are somewhat resource-hungry. Though Ruby on Rails take up more resources than Laravel, the developers still managed to minimise the consumption of resources. Users who are new to Laravel may find that their apps run slower compared to those that are created with Ruby on Rails.

Of the two web frameworks, Ruby on Rails does have some problems with scalability, which is more than Laravel. The main reason why Rails have scalability problems that are higher than Laravel is because RoR lacks performance and this is what makes it really very slow. Therefore, Laravel is better suited for performance and scalability.
