Feature flags have transformed gradual rollouts and now empower teams to control releases
I love the Flagsmith user interface, which is so easy to understand and get onboarded, making it super convenient to use for both developers and non-technical folks. Flagsmith offers support for a wide variety of programming languages, powerful segmentation for targeted rollouts, analytics to track feature performance, and security features such as audit logs and role-based controls. The user interface is very intuitive and easy to navigate, making it easy for new people to learn or get onboarded quickly, both for technical and non-technical users. Flagsmith provides useful governance and security capabilities for managing feature flags, including role-based access controls, permissions, and audit logging to help my team manage changes and maintain accountability. Flagsmith's accuracy and reliability come primarily from its feature flag management and controlled release capabilities rather than dedicated AI functionality, helping my development team manage feature rollouts, target specific user groups, and quickly disable features when issues arise. Flagsmith integrates well into my AWS-based development environments through its APIs, SDKs, and deployment flexibility.

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.

Quotes from Members

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

Pros

"Flagsmith has made managing software releases for a platform as complicated as ours much easier."
"The user interface is very intuitive and easy to navigate, making it easy for new people to learn or get onboarded quickly, both for technical and non-technical users."
"Harness has positively impacted my organization as several teams have already migrated to it, and some are in the process of moving, reducing the dependency on one specific platform and making it faster with shortened build times and much faster deployments."
"Approximately seventy-five percent time was reduced in case of deployment and around sixty to sixty-five percent time was reduced while troubleshooting it."
"Everything in Harness is configured and runs smoothly."
"Harness starts integrating with organizations, making everything automated without the need for manual interruption."
"By adopting templates and various different pipelines across our own IDP platform, we have saved upwards of 30 to 40% of development time and also reduced risks of failures or error rates by upwards of 70%."
"The features of Harness are valuable, supporting rolling deployments, basic deployments, and blue-green deployments with zero downtime."
"Some of the best features of Harness include powerful CI/CD pipeline automation, intelligent deployment strategies, and building monitoring, and its automation capabilities significantly improve speed and reliability while saving time by reducing manual operational tasks and the number of employees needed for deployments."
"Harness has impacted my organization positively; we use Harness in most of all deployments, so it is uniform."
 

Cons

"Regarding how Flagsmith can be improved, I think more advanced built-in analytics and experimentation capabilities would be beneficial for our development teams."
"When integrating Harness with more than twenty applications in one place, it becomes less stable, causing improvements to be necessary."
"Harness setup and configurations could be made easier to configure, which would be helpful."
"There are some UI components that can be improved."
"The licensing cost can be significant for larger teams, which should be taken into account."
"The initial setup can be complex and time-consuming, and the advanced features may require some learning time due to a steep learning curve."
"I prefer the previous less compact UI version of Harness, which showed more details on the screen."
"One improvement I see for Harness is simplifying the configuration process for smaller teams or startups, as the platform offers powerful features that new users may require some time to understand."
"Infrastructure as code or pipeline as code is something that Harness severely lacks."
