FeatureHub vs Zenmanage

FeatureHub is a runtime control plane for managing feature flags, configuration, and operational controls across environments. Feature flags and configuration values can use strings, numbers, or JSON. Teams can target rollouts by criteria or percentage, including gradual releases and A/B experiments. SDKs can receive updates through real-time Server-Sent Events or REST requests. The site lists SDKs for JavaScript, C#, Java, Python, Ruby, Dart, and Swift, while its SDK languages list also includes Go. Documented integrations include Slack, Google Analytics, and webhooks for feature updates. The Open Source edition is self-hosted and installed with Docker; deployment documentation also describes Docker and Kubernetes options. FeatureHub SaaS costs $4.99 a month per user, billed monthly, with separate pay-as-you-go charges for API requests: Streaming is 0.38 USD per 10K requests, REST is 0.35 USD per 10K, and Test is 0.33 USD per 10K. A 30-day trial includes 10,000 API requests and requires no credit card. FeatureHub says its SaaS service encrypts data transfers with SSL certificates issued by Google Cloud and Fastly.

Zenmanage is a feature flag management platform for controlling feature releases and changing application behavior at runtime. It supports boolean, string, and numeric flags, with default values and fallbacks for when the service cannot be reached. Teams can target flags using user or application context, group contexts into reusable segments, and release features gradually through percentage ramps and cohorts. Remote configuration allows behavior changes without redeploying code.

The service is available on the web and through an API. Listed SDKs cover JavaScript/TypeScript, PHP, Laravel, Python, Go, and .NET; REST APIs and webhooks are also listed. The Management API can create and update flags and targeting rules, and read audit history with scoped Bearer tokens. Permissions can be limited by account, project, or environment, including restrictions on production changes. Audit records include actor and environment details, and the maker says they cannot be edited or deleted. Zenmanage offers a free plan and paid plans from $29/mo, plus a 30-day Team-feature trial with no credit card required.
