Executive Summary

Review summaries and opinions

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

ROI

Sentiment score
9.0
Harness enhances deployment efficiency, reducing release times, improving processes, and decreasing failures, saving up to 40% development time.
Sentiment score
8.0
TeamCity enhances build efficiency and deployment across time zones, supporting automation for optimized resource allocation and ROI evaluation.
Time is saved because we now save engineering time. Before, it required two to three engineers actively monitoring production during deployments, but after starting to use Harness, there is zero or minimal manual monitoring.

Scalability Issues

Sentiment score
7.7
Harness is scalable for large enterprises, though stability issues may arise with integrations exceeding 20 applications.
Sentiment score
7.3
TeamCity enables scalable deployments with multiple agents, requiring regular maintenance, effectively supporting large-scale projects and numerous users.
It is able to work on our infrastructure side, which is EKS, and we are able to handle our organization growth effectively for an enterprise use case.
Technical Associate at ZS
Our entire organization uses it with hundreds of applications, and it supports this scale effectively.
Senior Software Engineer at a financial services firm with 10,001+ employees
When I integrated Harness to more than 20 applications in one place, it becomes less stable.

Stability Issues

Sentiment score
7.2
Harness is stable with prompt support, though integration of multiple applications may reduce stability, and occasional downtime occurs.
Sentiment score
7.7
TeamCity offers high reliability and stability, with minimal disruptions and effective resource management, despite occasional minor lags.
We have rarely faced issues with Harness tech support.
Senior AWS Consultant at Quantum Integrators
Harness is decently stable.
Technical Associate at ZS
 

Room For Improvement

Harness should streamline setup, enhance security and stability, simplify configurations, and revamp the UI to outperform competitors.
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
Flexible pricing models and more essential features in lower tiers could address this issue.

When deploying multiple components to multiple environments, like production and BCP, failures sometimes occur.

Setup Cost

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.

Valuable Features

Harness simplifies code deployment with automation, visual tools, AI error detection, and secure, downtime-free deployment methods.
TeamCity excels in build step flexibility, plugin support, cross-platform capabilities, Git integration, and intuitive usability for efficient pipeline management.
Meantime to recovery (MTTR) improved from 30 to 60 minutes before Harness to 5 to 10 minutes now.
Site Reliability Engineer at a tech vendor with 1,001-5,000 employees
Harness uses AI to suggest errors in case of deployment failures.
Senior Software Engineer at a financial services firm with 10,001+ employees
One of the best features Harness offers is the ability to templatize pipelines.

Automated delivery has made production releases safer and has reduced deployment incidents
The first point for improvement is the steep learning curve, where concepts such as services, environment, pipelines, and templates take time to understand. New users often need training before becoming productive, resulting in slower initial onboarding compared to simpler CD tools. An improvement idea is better guided onboarding with more opinionated defaults and examples. The second improvement can be on UI complexity and navigation; the UI can feel cluttered with many options and finding past executions, logs, or specific settings sometimes takes extra clicks, leading to small but noticeable productivity loss. Simplified UI views for common workflows and improved search and filtering could help. I also see cost and licensing as potential areas for improvement, as pricing can feel high for small teams and advanced features are tied to higher tiers, which may limit adoption for startups or smaller organizations. Flexible pricing models and more essential features in lower tiers could address this issue.

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.

I generally find TeamCity a lot more intuitive than Jenkins.
Moving to TeamCity from Jenkins At work, we’re slowly migrating from Jenkins to TeamCity in the hope of ending some of our recurring problems with continuous integration. My use of Jenkins prior to this job has been almost strictly on a personal basis, although I pretty much only use Travis…
