Mojolicious vs Yesod: What are the differences?

Mojolicious: Perl real-time web framework. Back in the early days of the web, many people learned Perl because of a wonderful Perl library called CGI. It was simple enough to get started without knowing much about the language and powerful enough to keep you going, learning by doing was much fun. While most of the techniques used are outdated now, the idea behind it is not. Mojolicious is a new attempt at implementing this idea using state of the art technology; Yesod: A RESTful Haskell web framework built on WAI. Yesod believes in the philosophy of making the compiler your ally, not your enemy. We use the type system to enforce as much as possible, from generating proper links, to avoiding XSS attacks, to dealing with character encoding issues. In general, if your code compiles, it works. And instead of declaring types everywhere you let the compiler figure them out for you with type inference.

Mojolicious and Yesod can be categorized as "Frameworks (Full Stack)" tools.

"Open source" is the primary reason why developers consider Mojolicious over the competitors, whereas "Haskell" was stated as the key factor in picking Yesod.

Mojolicious and Yesod are both open source tools. It seems that Mojolicious with 2.12K GitHub stars and 498 forks on GitHub has more adoption than Yesod with 2.11K GitHub stars and 329 GitHub forks.

Binary.com, WebbyLab, and MynewMD are some of the popular companies that use Mojolicious, whereas Yesod is used by DoxIQ, FP Complete, and SimplyRETS. Mojolicious has a broader approval, being mentioned in 9 company stacks & 3 developers stacks; compared to Yesod, which is listed in 5 company stacks and 5 developer stacks.
