Additionally, the segment functionality facilitates A/B and multivariate testing, providing a means to implement beta programs that can garner valuable early feedback from users. Flagsmith also promotes efficient deployment organization through the creation of projects and organizations, along with the assignment of roles to team members. Moreover, you can further enhance the Flagsmith experience by integrating it with your preferred tools and services, ensuring a comprehensive development ecosystem.

CloudBees provides a comprehensive software delivery platform that empowers developers to accelerate innovation through self-service and scalable workflows that are both repeatable and compliant. With our solutions, you can enhance the safety and speed of your software releases. Effective management, release, and monitoring of features can be achieved at scale, ensuring that visibility extends beyond a single pipeline. By orchestrating your entire software delivery process, you can experience a transformative approach to project management, often referred to as "meta" orchestration. This allows you to evaluate, communicate, and quantify the effects of software delivery on overall business success. Our platform answers all your inquiries regarding software delivery analytics, ensuring that compliance is maintained throughout every phase, including production. By automating the identification of potential risks, you can address them proactively instead of waiting for builds, troubleshooting bugs, or rewriting scripts. This shift enables you to concentrate on what truly matters: feature management and efficient workflows. Furthermore, you can streamline automation for compliance, security, and governance while maintaining the necessary flexibility. Ultimately, a confident development team leads to happier developers, reinforcing the idea that software delivery should be treated as a vital business function. Proactively managing risks is essential for sustained success.

Each module can function on its own or in combination to form a robust integrated pipeline that encompasses Continuous Integration (CI), Continuous Deployment (CD), and Feature Flags. All Harness modules leverage the capabilities of AI and machine learning to enhance their performance. Our algorithms are designed to verify deployments, pinpoint opportunities for test optimization, suggest recommendations for cloud cost savings, and restore the system to its previous state in the event of a rollback. They also play a crucial role in facilitating complex deployment patterns, identifying anomalies in cloud costs, and initiating a variety of other tasks. Staring at dashboards and logs post-deployment can be tedious; let us handle the monotonous tasks for you. Harness systematically evaluates the logs, metrics, traces, and other relevant data from your observability systems to assess the health and status of each deployment. If a problematic deployment is identified, Harness is capable of automatically reverting to the most recent stable version, ensuring a seamless experience for users. This automation not only saves time but also minimizes the risk of human error during critical deployment processes.

Hypertune is a remarkably flexible platform that specializes in the management of feature flags, A/B testing, analytics, and application configuration. It boasts a robust architecture that ensures end-to-end type safety and incorporates a version control system inspired by Git, along with the ability to conduct local, synchronous, in-memory evaluations of flags. You can create type-safe, customized input parameters like the current User or Organization to refine feature flag rules, which helps in precisely targeting the intended audience. Additionally, the platform supports the development of reusable variables, such as user segments, which can be applied across different feature flags, thereby simplifying the debugging process for specific users. Hypertune offers an array of options including A/B testing, percentage-based rollouts, multivariate tests, and machine learning loops, enabling a seamless process for rolling out, testing, and optimizing new features. You also have the capability to log analytics events using type-safe custom payloads and can generate dynamic funnels and charts on the dashboard for evaluating the impact of each feature release. Furthermore, the SDK allows for initialization with only the essential feature flags, permitting partial evaluations of flag logic at the edge, which significantly boosts both performance and security. This diverse set of features positions Hypertune as an exceptional tool for developers who are eager to innovate and enhance their applications, ensuring they can adapt swiftly to changing requirements. With its user-friendly interface and powerful functionality, Hypertune empowers teams to make informed decisions based on real-time data.
