Room For Improvement

Simplify configuration, improve UI, expand features, clarify pricing, and enhance security to improve accessibility and functionality for smaller teams.
TeamCity's complex setup, poor UI navigation, and integration issues hinder efficiency, with needs for API, reporting, and alert improvements.
There is not a lot of good support for pipeline as code, and I often find myself not using pipeline as code the way other platforms such as GitHub Actions or Jenkins integrate pipeline as code.
Technical Associate at ZS
Improved documentation and onboarding tutorials would help accelerate adoption.
Cloud Platform at Futurescape
One key area for improvement is simplifying the onboarding of new users; the reduction of platform complexity will help new users understand how all components interact, which feels initially very difficult.

Setup Cost

Harness pricing is higher than open-source but justified by benefits, with room for improvement in licensing cost noted.
TeamCity offers a developer-focused solution with scalable costs but requires an initial server setup expense despite a free version.
From what I understand with respect to Harness, licensing and setup costs were relatively low for an enterprise, and the pricing was more catered toward enterprises who would invest in the technology.
Technical Associate at ZS
However, once Harness was fully integrated into our workflow, the operational benefits became clear, justifying the investment for our use case, despite the slightly higher cost for smaller teams.
ML Engineer at a energy/utilities company with 51-200 employees
The licensing cost is a little bit too high.

Valuable Features

Harness simplifies CI/CD automation with AI-driven processes, enhancing deployment speed and reliability while reducing risks and manual effort.
TeamCity excels in build step flexibility, plugin support, cross-platform capabilities, Git integration, and intuitive usability for efficient pipeline management.
Harness uses AI to suggest errors in case of deployment failures.
Senior Software Engineer at a financial services firm with 10,001+ employees
The platform also supports cloud-native environments and Kubernetes deployments, making pipeline management easier, and its automation capabilities significantly improve speed and reliability.
Cloud Platform at Futurescape
The unified platform through Harness is extremely valuable because it has reduced our tool sprawl; instead of maintaining separate CI/CD, feature flagging, and verification tools, we can now manage everything effectively.

Templatized pipelines have improved efficiency while limitations in code-based development remain
Harness UI can do a lot of good things. Harness's UI should not feel very complicated. At the current stage, it feels very commercialized and compared to other platforms such as Argo CD or Jenkins, which feel much more lively and much more simple. Infrastructure as code or pipeline as code is something that Harness severely lacks. There is not a lot of good support for pipeline as code, and I often find myself not using pipeline as code the way other platforms such as GitHub Actions or Jenkins integrate pipeline as code. Pipeline as code is definitely one of the disadvantages when it comes to Harness. Additionally, the entire platform feels very commercialized, which is something that a lot of developers, especially open-source enthusiasts, might not appreciate even within the organization. One of the very important key factors I observed was that there is no way to execute nested pipelines, which means that we cannot execute child pipelines within child pipelines and child pipelines even within those child pipelines. There is no way to execute nested pipeline execution, which may or may not be required based on the use case, but it is definitely one of those features that I wish the platform had.

Versatile agent support boosts builds but UI and setup costs need refinement
TeamCity's user interface could be improved; specifically, the tree structure on the homepage is not clear, making it difficult to search for projects. Moreover, there are some limitations related to the version we were using. For instance, there were issues with agent specifications for particular build jobs and a timeout issue where jobs running longer than three hours would fail automatically.
