When comparing Yii vs Meteor, the Slant community recommends Yii for most people. In the question“What are the best backend web frameworks?” Yii is ranked 21st while Meteor is ranked 34th. The most important reason people chose Yii is:
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.

Pros
Pro Rapid development through code scaffolding
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.
Pro Comes with important security standarts
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
Pro Highly extensible
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 . '"' : '';
}
}
Pro Integrated with a testing framework
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.
Pro Lots of plugins available
Yii has about 2000 addons hosted on Yii's official website. These addons significantly decrease development time and increase the developer's efficiency.
Pro License
Yii is free and open source and is distributed under the BSD License.
Pro Strong community support
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.
Pro Easy to install
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.
Pro Best framework for CRUD operation
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.
Pro Highly extensible without effort
Pro Easy to learn
Meteor was developed with simplicity in mind, even for beginners who have just started using JavaScript frameworks. One of the reasons that beginners should start with Meteor is that Meteor is a full-stack framework, this way they can get the complete learning experience when it comes to web development (back-end and front-end development), all by using a single platform and a single language.
Furthermore, Meteor does not have complex and esoteric concepts that may be hard to grasp by a beginner, it has a clear documentation and well-established coding conventions.
There's also a very useful resource for learning Meteor in the form of a book: Discover Meteor, by the authors of many Meteor packages.
Pro Full-stack reactivity
Changes in the database will be propagated to all subscribed clients in real time, without you having to write any code.
Pro Isomorphic package system
A Meteor package can supply code for both the client and the server, and for mobile (Cordova) apps. For example, an autocomplete package supplies both server code to search a collection, and client code to display the results. The mdg:camera package supports the native camera if the app is built for mobile, or the HTML getUserMedia API to take pictures from the browser.
Pro Built-in security
Meteor takes care of many concerns with it's out-of-the-box security measures.
Pro Seamless communication between client and server
Meteor is built on top of Node.js and jQuery on the client.
Meteor enables the client and server to communicate data seamlessly, in real-time. You don't have to write any REST API or pub/sub code - Meteor takes care of it all automatically for you.
Pro Integrated front-end library
Meteor uses both your existing front-end library and it's own library called Blaze, which is integrated beautifully in the framework and fulfills the purpose of a true MV* front-end framework.
Pro Auto reload/refresh (hot code push)
Every time a change in the source file is saved, all connected clients will refresh automatically - browser tabs, mobile apps running in the simulator or on the physical device.
Or, deploy a Meteor app (meteor deploy myapp
) and all clients, plus all mobile apps with the server set to myapp.meteor.com
will automatically reload to use the code changes.
This drastically reduces the development cycle for apps in the App Store, where a regular update can wait for one to two weeks before being approved.
Pro Popular
Meteor is the 10th most starred project on GitHub and has overtaken even Rails.
Pro Support for MySQL, PostgreSQL and Redis
While Meteor only supports MongoDB and Redis natively, MySQL support is on the roadmap, and there are 3rd-party packages that integrate MySQL reactively with Meteor to some extent, such as numtel:mysql. For reactive PostgreSQL support, there is numtel:pg.
Pro Real-time testing framework
Meteor also has an official testing framework called Velocity. Velocity enables real-time unit testing and integration with Jasmine or Mocha syntax. Tests are automatically run when code is saved and the testing result is indicated by a green or red dot in the upper right corner of the app.
Pro Includes latency compensation
The client will mimic instant server-side response, and updates automatically if it was different once the information is available.
Pro Mobile apps from the same code base
Meteor can generate mobile (iOS and Android) apps from the same codebase as the web app, using the Cordova (PhoneGap) library (which brings native device functionality to JavaScript applications).
Meteor-generated mobile apps are JavaScript, HTML and CSS bundles that run in a UIWebView (on iOS) or WebView (on Android). Apps can be run locally in the iOS/Android emulator, or on physical devices. You can also publish them to Google Play Store or Apple's App Store.
Moreover, these hybrid mobile apps benefit from hot code push, which dramatically accelerates the development cycle.
Pro Eliminates the need to look for a database to use
Meteor uses MongoDB, eliminating the choice among NoSQL databases. MongoDB is highly scalable - used to store petabytes of data and perform billions of operations daily at eBay, FIFA, Adobe, Craigslist, McAffee, Foursquare and others.
Pro Gets rid of Node's callbacks
Although Meteor's server side runs on top of Node.js, it manages to avoid callbacks by making use of Fibers.
Pro Extensive ecosystem
Meteor's package repository called Atmosphere has more than 5000 packages available. What's more is that Meteor can also use into the packages available for the Node ecosystem.
Pro Powerful performance monitoring tools
Meteor uses Kadira which is an excellent performance monitoring tool for Meteor apps. It profiles CPU and RAM consumption, subscription latency and throughput etc.
Pro VC-funded open-source
Bright future for Meteor - funded by venture capital and open-source.
Pro In-app debugging
The community behind Meteor has created a useful application for debugging Meteor apps that will automatically delete collections and display client-side documents, allow you to control subscriptions and lets you modify the documents.
Meteor also has great support for server-side debugging, and WebStorm has also released full support for Meteor, including debugging capabilities.
Cons
Con Can be hard for beginners
Since Yii requires developers to write code following certain rules, or in other words, it requires developers to follow the "Yii way of doing things" it can be hard for beginners to warm up to it and start using it right away.
Con Not very good at many to many relations
(but there is a good plugin, namely CAdvancedArBehavior extension to do this)
Con No native SEO support (no server-side rendering)
Meteor does not have support for server-side rendering of views, which is extremely helpful when it comes to SEO. However, there's a third-party server-side rendering package available for download. The Meteor team has also said that server-side rendering is on the roadmap.
Though lately Google has announced that the search engine can render JS and CSS files just like modern web browsers

Con Officially supports only MongoDB, which is well-known to have issues with data integrity
MongoDB advertises scalability but only if you don't care about data-integrity. There are other backend options but none of them are officially supported.

Con Requires reliable network connection
It's common for the front-end and back-end to lose sync if an internet connection is flaky. Even though the connection should be in real-time, if the connection is weak, you may lose that real-time sync. For example, in chat applications you may have to refresh the page to get the latest updated data from the server.
