Are you a Quality Assurance (QA) engineer struggling with these daily challenges?

It works in development, but you can't test it in staging right away because there's no data.

The combination patterns for each feature are too complex to test everything.

In today's world, where development cycles are sped up by Generative AI, the role of QA is more important than ever. Yet, preparing test environments and testing complex feature combinations takes a lot of time and can slow down development.

What if you could freely switch specific features ON or OFF without changing any application code or environments?

This article will show you concrete ways to use Bucketeer, a feature flag and A/B testing platform, to solve the problems QA engineers face and drastically improve test quality and efficiency.

Improving a website or application inevitably involves releasing new features and changing designs. However, every change carries inherent risks: "Will this break something?" or "Will this negatively impact the user experience?"

This article explains how to use a powerful technique called feature flags to manage these risks and effectively run A/B tests that are both safe and data-driven, complete with practical examples.

Almost two years ago, we made our in-house product, Bucketeer, open-source, starting with version 0.1.0. Since then, through extensive use across multiple projects, we have established its stability and reliability, leading us to the milestone release of version 1.0.

Feature flags contain various elements such as ID, name, tag, etc., and managing them can be hard sometimes. As the number of feature flags increases, finding the desired information using a simple list display becomes challenging. Bucketer provides a search filter function that allows you to search based on ID, name, etc., and filter by tags, administrator, etc. However, there are many different ways to search for feature flags, and various patterns exist. Therefore, setting different search conditions each time to search for information can be tedious and waste time and effort. In this article, we will introduce a feature that allows you to save search condition shortcuts, which can be helpful in such situations.

Efficiency and automation are essential for operating any system or service. Feature flags are a technology for dynamically turning on or off certain features in software development, but managing them manually can take time and effort.

Bucketeer's Multi Schedule feature is a powerful tool for solving that problem. In this blog, we'll explore what Multi Schedule is, its key benefits, and practical examples of how it can be used effectively.

In Feature Flags management, it's useful for users to control Feature Flags automatically at specified times or when certain specific events occur.

In Bucketeer, we offer scheduling functionality with Auto Operations to specify dates and times, an event rate feature to set target thresholds for goal events, and a Progressive Rollout feature that allows you to roll out your feature gradually.
