Best Feature Management Software for Kubernetes

Flagsmith is a fully supported open-source Feature Flag, Remote Configuration, and A/B testing tool. You can use our hosted API to deploy to your private cloud or on-premise. Flagsmith makes it easy for you to create and manage feature flags across web, mobile and server-side applications. Flagsmith allows you to toggle the feature on or off in different environments, users, or user segments by wrapping a section of code with a Flag. Feature flags - Release new features with confidence using phased rollouts. Remote configuration - You can toggle individual features on or off and make changes without having to deploy new code. Segments for A/B Testing and Multivariate Tests - Use segments to perform A/B or multivariate testing on new features. Segments can also be used to introduce beta programs in order to gain early user feedback. Organization Management - Help keep your deployment organized by creating projects and organizations, as well as assigning roles to team members. Integrations - Enhance Flagsmith with your favorite tools.

Octopus Deploy was founded in 2012 and has enabled successful deployments for more than 25,000 companies worldwide. Octopus Deploy was the first release orchestration and DevOps automation tool. They were limited to large enterprises, slow, and didn't deliver on their promises. Octopus Deploy was first to be adopted by software teams. We continue to innovate new ways for Dev & Ops to automate releases and deliver software to production. Octopus Deploy provides a single location for your team: - Manage releases - Automate complex application deployments - Automate routine or emergency operations tasks Octopus is different because it focuses on repeatable, reliable deployments and has a deep understanding about how software teams work. Octopus is our philosophy about what makes good automation. This philosophy has been refined over a decade of many thousands of successful deployments. Octopus is designed to handle the most complex deployments.
