Bucketeer

Purpose: Bucketeer is an open-source feature flag platform for reducing deployment lead time and release risk.
Feature flags: It can enable or disable features in real time without deploying code and supports dark launches and staged rollouts based on user attributes, devices, and segments.
Experimentation: Bucketeer uses Bayesian probabilities for A/B testing and says this can produce results with smaller sample sizes.
Rollouts and targeting: Features include progressive rollouts, reusable user segments, date-based targeting, flag-based targeting rules, and flag prerequisites.
Automation: Auto operations can schedule flag changes, respond to event rates, and use webhook triggers for CI/CD or APM integrations including Datadog, New Relic, and Dynatrace.
Integrations: The maker lists Slack notifications, Firebase Cloud Messaging push updates, webhooks, a RESTful HTTP API, and OpenFeature compatibility.
Security and governance: Listed controls include environment-level Viewer, Editor, and Owner roles, audit logging, separate client, server, and public API keys, and environment isolation.
SDKs: Client SDKs are listed for Android, iOS, Flutter, JavaScript, React, and React Native; server SDKs are listed for Go and Node.js.
Self-hosting: Deployment options include Docker Compose for lightweight setups and Kubernetes with Helm for production; the page says the platform can scale to 100M+ users.
Evaluation modes: The maker says server SDKs support local and remote evaluation, while client SDKs evaluate remotely.
API limit: The documentation labels the HTTP API as Alpha.
Support: The maker directs users to the Bucketeer channel in Cloud Native Slack for questions and community discussion.
