Why we built Lekko: For 3 years I worked at Uber where I had the opportunity to work with Flipr, a dynamic configuration system that powered the entire business. We used it to make our software flexible for product and operations to change dynamically as the business required. As software engineers, we used it wherever we could, this let us respond rapidly and safely to changing markets and new requirements. When I left Uber to join a much smaller company, I immediately felt the pain of not having those tools at my disposal. I led my new team in implementing a feature flagging system, but it quickly became clear that existing tools fall far short of solving the problem. Feature flags added complexity, created difficulty debugging or reproducing issues, exposed applications to misconfigurations that caused issues for customers and led to churn churn, and ultimately frustrated the engineering team so much that the usage was limited. The problem Engineering teams today are expected to build software rapidly in an uncertain world. Existing feature flagging systems fall short because they have too tough of a tradeoff between the added speed and the risk and complexity that they introduce. Moreover, unintended outages often occur due to changes bypassing standard software controls like CI, reviews, and tests, leading to misplaced blame on the engineering teams and a lack of access for the rest of the business. How it works Lekko goes beyond feature flagging by offering a FAANG-class dynamic configuration system that minimizes risk while improving speed. Instead of defining feature flags in an external store, Lekko allows engineers to decorate functions written in their native language. Lekko wraps these functions to make them changeable at at runtime through our web based UI for software engineers and teammates who don’t write code. Lekko sits in your code so it’s easy to test locally, it doesn’t bypass CI/CD, and issue prevention can take advantage of code understanding AI to predict and prevent potential problems before they happen. With ten binary flags you have 1024 possible configurations, making it almost impossible to test every variation. So we allow you to group configurable functions and define legitimate configurations so that daily changes can be handed of to product, customer success, or sales without creating risks or the need to interrupt engineers for every small change.
