Featureflip vs FeatureHub

Featureflip provides feature flags for changing functionality in a running application without deploying new code. It supports percentage rollouts, targeting rules, kill switches, A/B tests, and isolated environments. When a flag is no longer needed, its GitHub Action can open a reviewable pull request to remove the code path across thirteen languages and archive the flag after merge. Teams can manage flags through a REST Management API or evaluate them through the Evaluation API; thirteen SDKs and OpenFeature providers are listed. Server SDKs evaluate locally from in-memory configuration and keep using the last configuration if the service is unreachable. Featureflip also offers an MCP server for Claude Code, Cursor, Copilot, and Cline, plus a Terraform provider. Its service and PostgreSQL database run on Hetzner Cloud in the European Union. The Free plan is free and is limited to one project, 10 flags per project, two environments, and up to three team members. Team is $49 a month; Pro is $99 a month; Business is $249 a month. Enterprise pricing is negotiated directly.

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.
