Review on Immutable by Nathan Jones

It is very easy to use with no hassle of configuration or deployment issues as it comes pre-built in different languages like Python/JavaScript etc., so you don't have worry about that part at all! The support team has been really helpful too when I was stuck somewhere during my implementation process alongwith their documentation available online are also great assets here!! Nothing much but if your looking out an open source solution then this should be one option worth considering because they provide multiple language options including JavaScript (NodeJS), Java(JEE) &Python3/.NetCore2 API's apart from RubyOnRailsAPI✔s - So there might not always exist such kind solutions where we can get our hands dirty by writing code ourselves! Highly recommended!! As stated above its pretty straight forward approach without any complexities involved while using them hence good fit into small teams who want something simple yet powerful.
