In their own words
feat
feat is a hosted feature-flag platform for early engineering teams. Server SDKs evaluate flags locally, so each flag read does not require a network call; changes stream to connected SDKs in under a second. Targeting rules combine conditions across users, devices, organizations, sessions, and requests using AND and OR. Sticky percentage rollouts keep a user, device, or organization on the same variation across requests and sessions. First-party SDKs are available for Node.js, Bun, Deno, Go, Python, Ruby, browser JavaScript, and Flutter/Dart, with OpenFeature providers for web, Node.js, and Dart. Metric sources include Segment, Mixpanel, PostHog, and custom sources. The Free plan costs nothing and includes 7,500 MAU, 100 server connections, two projects, unlimited environments, and unlimited flags. Starter costs $19 a month, with annual billing listed at $15/mo. Built-in statistical experiments, variant tracking, metric integrations, auto-advance gradual rollouts, and Slack integration are listed as coming in Q3 2026, not current features.
FeatureHub
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.
