Featurevisor

Featurevisor is an open-source framework designed for developers to manage feature flags, A/B tests, and remote configuration in a declarative manner. It enables teams to control these aspects directly from their Git repositories, supporting workflows that integrate configuration with version control. The tool provides a structured way to define when and for whom features are enabled, such as targeting users in specific segments or regions.

Developers can use Featurevisor across different environments, as it is platform-agnostic and works in frontend, backend, and mobile contexts. js, Go, Swift, and Java. This allows integration with a broad range of technology stacks. Featurevisor supports fetching configuration data from a CDN or a custom server, giving flexibility in how feature data is delivered to applications.

The tool is distributed under the MIT License, emphasizing its open-source nature and a commitment to avoiding vendor lock-in. It can be self-hosted on the user's own infrastructure, allowing teams full control over their feature management system without requiring an enterprise contract. Featurevisor is positioned as a purpose-built solution for managing feature toggles, experiments, and remote configuration declaratively, helping developers build and deploy products with greater control over feature rollout.

Featurevisor belongs to the class of feature management frameworks, providing capabilities for classic feature toggles, targeted rollouts, and experiment management directly from code and configuration files.
