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.
GO Feature Flag
GO Feature Flag is an open-source feature-flag management system built on OpenFeature for infrastructure you control. Its relay proxy runs locally with Docker and a flag configuration file. Teams can target users and segments, use percentage or progressive rollouts, schedule changes, and run A/B tests. Client and server SDKs are listed for 16 languages and frameworks, including JavaScript, TypeScript, React, Swift, Kotlin, Go, Java, Python,.NET, Ruby, Rust, and others. Retrievers load configuration from HTTP(S), local files, Kubernetes ConfigMaps, cloud storage, Git providers, MongoDB, Redis, and PostgreSQL. Exporters send evaluation data to Kafka, AWS S3, BigQuery, OpenTelemetry, webhooks, or logs. Notifications can reach Slack, Discord, Microsoft Teams, webhooks, or logs. The MIT-licensed Opensource plan costs nothing, billed forever, with all features, unlimited flags, and community support.
