Featureflow vs FeatureHub

Featureflow manages feature releases for engineering and product teams. It separates deployment from release: teams can deploy code silently, then enable features later without another deployment. Targeting rules can use individual users, cohorts, dates, times of day and custom attributes. Teams can roll features out by percentage or environment, organize users into segments and use instant kill switches. Release pipelines arrange ordered phases with environment mapping, default targeting and approval gates. Integrations include Slack, Jira, CI/CD webhooks, a REST API and AI assistants through MCP. SDKs are listed for a broad set of server and client technologies, including Java, Node.js, Python, React Native, iOS and Android. Feature flag and user data are encrypted at rest in a SOC II compliant data centre. The free plan supports five seats, one project, two environments and one million SDK requests monthly. Team is $99 a month; Business is $399 a month. Enterprise pricing is custom, and the service lists a 14-day trial.

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.
