Quick takeaways

Feature flagging tools can lead to technical debt and management difficulties, particularly as their complexity scales with software releases.

Lekko aims to enhance dynamic configuration by integrating feedback and AI capabilities, promoting safer and more efficient software deployment practices.

Deep dives

Challenges of Feature Flagging at Scale

Feature flagging tools, while useful for safe releases, often lead to management challenges as they scale. Teams frequently struggle with the growing complexity of understanding what each feature flag does, which can result in significant technical debt. The ease of adding flags without adequately cleaning them up can lead to a combinatorial explosion of code variations and unexpected bugs. Ultimately, the benefits of feature flags can become overshadowed by the difficulties in bookkeeping and risk management, especially when stale flags or unintended configurations are activated.

Feature flagging tools have grown in popularity as a way to decouple releases and deployment, but they can introduce their own long-term problems and tech debt.

Lekko is a startup democratizing the practice of dynamic configuration. Their motivating idea is to empower engineers to focus on software releases, and business teams and other stakeholders to shape deployment.

Konrad Niemiec is the Founder and CEO at Lekko. He previously worked at Uber where an internal tool called Flipr enabled dynamic configuration management, and which today serves as a key design inspiration for Lekko. Konrad joins the show with Sean Falconer to talk about his company and the technology they’re developing.
