FeatureHub vs Featurevisor

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.

Featurevisor is a Git-based tool for managing feature flags, experiments and remote configuration through YAML files in a Git repository. Teams build datafiles for each environment, deploy them and evaluate features through an SDK. Rules can target users in order, roll out a percentage and assign weighted experiment variations. Typed global and feature variables allow defaults and targeted overrides, with schemas validated during datafile builds. Applications fetch static JSON datafiles and evaluate flags locally in memory, without a network request for each decision; the datafiles are served from the customer’s own CDN. YAML test specifications can check expected behavior locally or in CI, with failed assertions returning a non-zero exit. Git pull requests and CI linting, tests and builds provide change control. Featurevisor is self-hosted and MIT-licensed. Its free plan is free, with no per-seat pricing or evaluation service to keep running. Listed platforms include Android, iOS, Linux, macOS, web and Windows.
