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.
