In their own words
Bucketeer
Bucketeer is an open-source, self-hosted feature flag platform intended to reduce deployment lead time and release risk. Teams can switch features on or off without deploying code, and use dark launches and staged rollouts based on user attributes, devices, and segments. Controls also include progressive rollouts, reusable segments, date-based targeting, flag rules, and prerequisites between flags. For A/B testing, Bucketeer uses Bayesian probabilities and says this can provide results with smaller sample sizes. Automated operations can schedule flag changes, react to event rates, or use webhooks for CI/CD or APM integrations such as Datadog, New Relic, and Dynatrace. Integrations also include Slack notifications, Firebase Cloud Messaging updates, a RESTful HTTP API, and OpenFeature compatibility. Governance features include environment-level Viewer, Editor, and Owner roles, audit logging, separate client, server, and public API keys, and environment isolation. Client SDKs cover Android, iOS, Flutter, JavaScript, React, and React Native; server SDKs cover Go and Node.js. Deployment options include Docker Compose and Kubernetes with Helm. The HTTP API is labeled Alpha.

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.
