Bottle vs Yii

Being a small one file distribution it includes almost every vital thing you need to support little websites (routing, templating). Everything else can be implemented using plugins.

Bottle works around the one-file approach, everything is done in a bottle.py file. This means that it's extremely easy to share and upload your application since it practically is just one python file.

It is so little there's no need to install, it is included in the standard libs python.

Using it with gevent is a breeze. It's a WSGI app so it's easy to make it work with anything.

Yii takes care of repetitive tasks through Gii, a web-based scaffolding tool. Gii takes care of code generation and creating code templates for:

• Models
• Controllers
• Forms
• Modules
• Extensions
• CRUD controller actions and views
• There are a lot of scaffolding templates made by community for Gii, that improve generated code functionality by a lot.
• Gii is very easy to extend yourself.

Since security is a crucial part of any application, Yii comes with great security features out of the box to help developers create a secure and reliable application. These security features contain but are not restricted to:

• Input validation
• Output filtering
• Features against SQL injection
• Cross-site scripting prevention

Yii is built to be extremely extensible. Virtually every component of the framework can be extended programmatically. For example, if you want to add a unique id to your views, it's very easy to do:

namespace app\components;

class View extends yii\web\View {

    public $bodyId;

    /* Yii allows you to add magic getter methods by prefacing method names with "get" */

    public function getBodyIdAttribute() {
        return ($this->bodyId != '') ? 'id="' . $this->bodyId . '"' : '';
    }

}

Yii makes use of Codeception, a great PHP testing framework that helps developers run their tests. They can be unit, functional or acceptance tests since Codeception supports them all.

Yii has about 2000 addons hosted on Yii's official website. These addons significantly decrease development time and increase the developer's efficiency.

Yii is free and open source and is distributed under the BSD License.

Yii has a strong and rather large community behind it. This is proven by the great number of blog posts, tutorials, guides and reviews on the Yii framework as well as the great number of extensions developed for it.

Yii uses Composer to handle it's dependency installation. This is rather easy and not very time consuming, although it should be noted that Composer is very resource-intensive considering what it's job is. But that is not really Yii's fault.

Yii Framework Provides most of features require for crud functionalities like GridView, Listview and DetailView (with jquery search and validation functions) by generating using GII.
