In simple English
Feature flags let you turn new parts of your software on and off without deploying new code. A/B tests let you show two different versions to different users and see which one performs better. Bucketeer is a self-hosted system that gives you these tools on your own server. You do not pay monthly fees to a third-party service, and your user data stays with you. Setting it up takes some effort because it runs several background services.
What it is
Bucketeer is an open-source feature management and experimentation platform. It combines targeted rollouts, Bayesian A/B testing, and user segmentation into a single dashboard.
What it is good for
Solo builders and teams who want advanced feature flags and experiment tracking without paying expensive per-user SaaS fees.
- Runs on your own infrastructure so you keep complete ownership of your data.
- Includes Bayesian A/B testing for faster statistical results with smaller sample sizes.
- Provides official software development kits for web, mobile, and server environments.
- Requires running multiple services like MySQL and Redis, making local setup complex.
- Demands server resources to handle databases, backend workers, and web gateways.
- Maintained primarily by a corporate team rather than a large independent community.
Paid feature flag services like LaunchDarkly or Split
Docker (a way to run a program inside its own sealed box, so it cannot break anything else on your server) and Kubernetes (a system for running and scaling containerized applications across many servers)
