FeatureHub review
Broad feature flag controls with open-source self-hosting and low-cost SaaS.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
FeatureHub is a feature flag, remote configuration, and A/B testing platform for mobile, web, and server applications. It supports management across applications and environments, with attribute-based targeting, percentage-based rollouts, reusable application strategies, feature groups, permissions, audit history, and webhooks. SDKs support Java, JavaScript/TypeScript, C#, Dart/Flutter, Go, Python, Ruby, and Swift, with client- and server-side evaluation. It is suited to teams that want production rollout controls while retaining a choice between hosted SaaS and open-source deployment.
Pricing is straightforward across two plans. FeatureHub SaaS costs $4.99 per user per month when billed monthly and includes unlimited feature flags, applications, and environments; API requests are billed separately. The Self-hosted Open Source plan costs $0 as a one-time price and runs on the team's own infrastructure. A 30-day free trial is also available. This structure gives budget-conscious teams a low-cost hosted entry point, while organizations that prefer infrastructure ownership can deploy the open-source edition without a listed license charge.
The strongest fit is for teams that need more than simple on/off switches. REST polling, SSE streaming, test APIs, targeting rules, percentage rollouts, feature groups, application strategies, and audit tracking support varied release and runtime-control patterns. Integrations include Fastly, Google Analytics, and Twilio Segment, and the platform covers web, iOS, Android, API, and self-hosted use. The trade-off is operational choice: SaaS users pay separately for API requests, while self-hosted users take responsibility for their own infrastructure. Choose FeatureHub for flexible rollout control and deployment choice; consider a narrower tool if basic flag management is all you need.
