Pros
Pro Large community
GitHub is the largest code host on the planet with over 21.4 million hosted repositories and many users. It's unarguably the largest VCS used by developers worldwide and as such, it has a vibrant community that follows it resulting in many guides and tutorials for new users. Even experienced developers can always find an answer to any question they may have.
Pro Nice and usable UI
GitHub's UI is clean and intuitive. Each view is designed to not fill the screen with useless information.
For example, the repository view displays only the most crucial data about that repo - on the top it displays the number of commits, branches, releases and contributors. When clicked, each of them will take the user to a page that displays more detailed information.
Pro Integrated issue tracking
GitHub has integrated issue tracking that makes hunting and solving bugs easy. Each project's issues page can be filtered by closed issues, assignees, labels and milestones. Issues are also sortable by age, number of comments and update time.
Pro Provides free hosting for static websites
GitHub Pages is a feature that allows developers to create websites for their projects or anything they need a static website for, for free.
Pro Anyone can fork
Any user can fork a project and submit a pull request. If accepted by the owner, the fork will be merged with the master branch.
Pro GitHub makes it easy to find open source projects
GitHub is the largest host in the world for open source projects. Developers from all over the world fork and work on countless projects hosted on it.
GitHub's search box is a powerful tool that allows developers to find open source projects in areas they are interested in and where they can immediately start to contribute.
GitHub also has a page dedicated solely at exploring and finding open source projects, grouping them by each topic they cover. In the same view, GitHub displays trending repositories and sorting them by day, week or month.
Pro Gist (Snippets)
Gists is GitHub's way to easily share code, text snippets or any kind of information with the world. They are an easy way to share text and they work as Git repos, which means that they are forkable and versioned. They are also fully compatible with Git.
Pro Simplified team management tools
GitHub has easy and useful features to control teams, large and small alike. Team members can be given different powers on different projects, ranging from the ability to create them, to only being able to have read-only access.
Pro Convenient continuous integration with Travis CI
GitHub can be integrated with Travis CI for code testing and deployment, furthermore it is free of charge for free open-source projects.
Pro Supports Two-Factor authentication
GitHub has added another layer of security to their user accounts. This layer comes in the form of Two-Factor authentication. After it's enabled, GitHub delivers an authentication code by SMS, or by a free application for smartphones. After two-factor authentication is enabled, the authentication code is sent to the account owner's phone any time someone attempts to sign into their GitHub account. This means that only someone who has both the password and authentication code can sign into the account.
Pro Easy integration with cloud hosting services
Many widely used cloud hosting services are easily integrated with GitHub. Any project hosted on GitHub can be set up on these services in seconds. Some companies that offer this feature are:
- Amazon Web Services
- Google Cloud
- Heroku
- Windows Azure
Pro Support for mandatory code reviews
GitHub allows maintainers to make code reviews mandatory for any repository they choose.
Pro Code search functionality
GitHub supports searching code. Whether it's from a specific project or from the whole website. What's more, GitHub has excellent SEO and you can easily find any line of code hosted on public repos on GitHub even from Google.
Pro Student discounts
GitHub offers very good student discounts along with other things, such as AWS credits.
Pro Additional features for academics
For those with a valid .edu email or valid school ID there are additional benefits such as free private hosting. While it may take time for the account to be verified, it can easily be worth it.
Pro Project management tools available
GitHub has a tool called (quite intuitively) "Projects". It helps teams to organize and prioritize the work they are doing by creating roadmaps and release checklists.
Pro Comprehensive documentation
The Sencha documentation is comprehensive, with detailed documentation and a number of examples displaying the various widgets, tools and themes.
Pro Supports MVC and MVVM development
Pro Supports Web and Mobile deployment out of the one framework or codebase
Pro Support for easy theming of applications
Pro Visual Design tool available
The Sencha Architect product allows you to visually build your application, or rapidly prototype a system.
Pro IDE Plugins available
A number of plugins are available for some of the commonly used IDEs (eg: JetBrains, Eclipse, Visual Studio), providing templates, refactoring support, hinting and code completion/generation, as well as management of includes and other time-saving features.
Pro Charting package included
Cons
Con Rule of thumb: 1GB per repository, 100MB per file
For most repositories this is acceptable, but for already large repositories with a long history, this may be a limiting factor.
Con Proprietary
Con Steals and sells your privacy
Con Limited web browser support
Modern web browsers like Waterfox are no longer supported, breaking basic UI elements and making the site unusable.
Con No OAuth2 support
In order to sign in to GitHub, users have to sign up first with unique credentials for GitHub only, so no option to sign in with Google+ or Facebook.
Con Owned by Microsoft
Con Very inconvenient UI
Very hard to switch between projects.
Con Sencha CMD is bloated and frustrating to work with
To do any meaningful development, you are stuck with CMD. There is a gulp task that will handle the JS concatenation, but there is nothing outside of CMD that can handle theming in their ecosystem.
In addition, CMD is based on Java, and is very heavy to run (600MB+ on Windows 10 to watch for changes in the application and recompile).
Con Sencha CMD (their CLI) is under documented, and out of date
Their latest release of CMD changed some configuration locations, but the documentation was not updated to reflect this. There is no reference guide on the json configuration files, other than the (unfortunate use of) comments in the generated json files.
Con They use proprietary extensions to SASS, making it incompatible with anything but their Fashion processor
On the plus side, you do not have to install ruby alongside CMD for more recent versions of ExtJS. However, their Fashion processor seems to only be available through CMD.
Con Too often breaking changes between versions. They have little concept of backwards compatibility
Compounded by the fact that there are now two "toolkits" in the same "version" of ExtJS, with certain components not existing in one vs the other.
Con The IDE tools are not sold separately - you must purchase the appropriate license pack
You get all the IDE plugins, even if you only need one. They should offer sell them individually, or continue to bundle them with a dev license pack.
Con Difficult to integrate with 3rd party software
Any third party library you wish to include has to be wrapped in some sort of component adapter. You have to do a lot of tweaking to get the build process right if you want the 3rd party lib to be bundled into your application in the right order.
Con Can be expensive
The framework is a commercial package, and the recent decision to start with a minimum of 5 users may rule out smaller developer teams or startups. Recently, they have started a program that allow essentially what are contractors to purchase single licenses, but not individual, independent developers.
