The easy of use of advanced features related with spring, the convention over configuration, the groovy language itself. All of that produces a very good piece of code that is easy to understand. Review collected by and hosted on G2.com.

Well sometimes some plugins don't work well when you put them all together and other times when I have some sort of bug I need to do a clean and compile to fix it. Review collected by and hosted on G2.com.

- Compared with other Java frameworks, you typically write less then 50% code which vastly improves maintainability

- Automatically generated and customizable CRUD pages

- Large, complex applications can easily be split up into self-contained sub-applications Review collected by and hosted on G2.com.

* convention over configuration

* relatively easy to learn

* many useful plugins

* built on top of mature technologies (Spring, Hibernate)

* Groovy-powered Review collected by and hosted on G2.com.

I love the conventional approach to web application development that Grails brought. Grails gives you a very simple "interface" to the complicated components that underly it, such as Hibernate, Spring, and some template engine, for example. It does a good job of finding the sweet spot between making it very simple/fast to do common things, and not-so-difficult to do more specialized things. Grails is similar to Rails - in fact it was inspired by Rails.

I loved the unit-testing support provided by the framework. It is quite easy to write tests for your Grails controllers and services. Review collected by and hosted on G2.com.

Using frameworks like Grails tends to leave you with monolithic beasts over time. I've tended to favor toward an approach where the UI and server-side are divorced. For example, an architecture with a "REST"-ful back-end (almost no server-side rendering) along with single-page apps for the front-end. Review collected by and hosted on G2.com.

Understandable and easy syntax. Easy way to import services. Easy way to handle lists/arrays.

A lot of plugins are available and easy to use. You can see changes only refreshing the page, no need to recompile witch saves a lot of time. Review collected by and hosted on G2.com.

The only downside I found is that it's hard to find an IDE that can read the syntax without buying intelliJ Review collected by and hosted on G2.com.

I like the easiness of the framework. One can really get a quick start on a project. Even if someone has started the development, he can also take advantage of it to create a prototype quickly. Review collected by and hosted on G2.com.

Black Boxed plugins. This is really a big challenge for us right now. Grails user should not depends up on the community driven plugin to fulfill their needs. Review collected by and hosted on G2.com.

Convention over configuration,

Less boilerplate code,

Development is fun and very easy,

I can focus more on business logic of the application rather then performing the framework ceremonies. Review collected by and hosted on G2.com.

Debugging is hard sometimes, I hope it is improved in Grails3 Review collected by and hosted on G2.com.

It was my first professional job, it made it easier to start since it makes the stack simpler than using Java. Review collected by and hosted on G2.com.

The community wasn't really big when I worked with Grails. Review collected by and hosted on G2.com.

Grails is a great tool that made my life easier, really like Integrated ORM / NoSQL support. Review collected by and hosted on G2.com.

I am a new user so im still learning about the tool. Review collected by and hosted on G2.com.

Super fast configuration for API, a lot of plugins Review collected by and hosted on G2.com.

Grails community is too small, too little examples with a new technologies for the beginners Review collected by and hosted on G2.com.
