Likelihood to Recommend I recommend JRebel for Java developers, it will remove the time needed for redeployment, it will increase the focus on the task at hand (without being distracted by the redeployment) and will make them happier. I recommend JRebel for Java Development Managers, they should purchase this for their teams - it will increase productivity, decrease the product's time to market, and it will save money for the company. The ROI can be calculated upfront and presented to higher level management for approving this, if needed.
Read full review TeamCity is very quick and straightforward to get up and running. A new server and a handful of agents could be brought online in easily under an hour. The professional tier is completely free, full-featured, and offers a huge amount of growth potential. TeamCity does exceptionally well in a small-scale business or enterprise setting.
Read full review Pros Deploys all layout changes consistently (when Instant Run was initially available, you couldn't tell if the change you made to a layout was actually being tested or not). Doesn't require a full build as often as Instant Run when changing code. Works with compile time annotation libraries like Realm, etc. Read full review TeamCity provides a great integration with git, especially Bitbucket. When a new code release (build) fails TeamCity has a great tool for investigation and troubleshooting. TeamCity provides a user-friendly interface. While some technical knowledge is required to use TeamCity, the design helps simply things. Read full review Cons It worked great, no big cons Read full review The customization is still fairly complex and is best managed by a dev support team. There is great flexibility, but with flexibility comes responsibility. It isn't always obvious to a developer how to make simple customizations. Sometimes the process for dealing with errors in the process isn't obvious. Some paths to rerunning steps redo dependencies unnecessarily while other paths that don't are less obvious. Read full review Performance The performance of JRebel is great. It is enabling the Java team to do hot re-deployments and it has to be transparent and fast for the user, otherwise the whole purpose of reducing wasted time with re-deployments doesn't make sense. Also the User Interface for License Server management and analytics loads fast and the navigation through pages is quick.
Read full review TeamCity runs really well, even when sharing a small instance with other applications. The user interface adequately conveys important information without being overly bloated, and it is snappy. There isn't any significant overhead to build agents or unit test runners that we have measured.
Read full review Alternatives Considered Hot code swapping doesn't have many players...it's mainly JRebel. We use JRebel a lot in our backend code development where it minimizes our development cycle (20min down to 30sec). For Android, the competitor is Android Studio's Instant Run which works fairly well now. For smaller apps, Instant Run is faster deploying but needs more full builds. With JRebel, you hardly ever need to do a full build.
Read full review TeamCity is a great on-premise Continuous Integration tool. Visual Studio Team Services (
VSTS ) is a hosted SAAS application in Microsoft's Cloud.
VSTS is a Source Code Repository, Build and Release System, and Agile Project Management Platform - whereas TeamCity is a Build and Release System only. TeamCity's interface is easier to use than
VSTS , and neither have a great deployment pipeline solution. But
VSTS 's natural integration with Microsoft products, Microsoft's Cloud, Integration with Azure Active Directory, and free, private, Source Code repository - offer additional features and capabilities not available with Team City alone.

Read full review Return on Investment It sped up the developing time, and time is money for the company. Read full review TeamCity has greatly improved team efficiency by streamlining our production and pre-production pipelines. We moved to TeamCity after seeing other teams have more success with it than we had with other tools. TeamCity has helped the reliability of our product by easily allowing us to integrate unit testing, as well as full integration testing. This was not possible with other tools given our corporate firewall. TeamCity's ability to include Docker containers in the pipeline steps has been crucial in improving our efficiency and reliability. Read full review ScreenShots
