Feature Flags for Product Growth:The Eucalyptus Story

Eucalyptus has three engineering teams. Two platform teams focus on the core technology while a growth engineering team works on metrics and product-market fit. One engineer, who joined from Atlassian brought a feature flag mindset to the team.

The tech stack includes React and Vue for the frontend, a shared Node.js backend, PostgreSQL for data, GraphQL for communication, and Prisma ORM. By sharing high-quality engineering and infrastructure across all brands, Eucalyptus keeps its technology efficient, scalable, and flexible. Feature flags are used on the frontend, with custom adapters built for both React and Vue applications with ConfigCat.

As a fast-moving startup, Eucalyptus wanted to release features faster and experiment with new ideas while always keeping the customer experience safe. Launching new features used to feel risky, especially for a small team. Eucalyptus needed a way to try bold changes and adapt to user needs fast without sacrificing stability or quality. Feature flags offered a way to innovate and grow safely.

Adopting ConfigCat's feature flag management platform made a real difference at Eucalyptus. Feature flags are now used for three main purposes. First, experimentation and A/B testing help the team see what users love. With data from Segment and Redshift, they know which changes work and which ones need a rethink. Second, progressive rollouts let Eucalyptus release high-impact features to a small group of users before going big, reducing deployment risks and improving release control. Third, kill switches mean that if something does go wrong, they can turn off a feature instantly and keep things running smoothly. Automatic flag caching in the ConfigCat SDKs also keeps the apps fast and reduces server requests, even on pages with lots of traffic.

Eucalyptus wanted a feature flag tool that just works and fits their modern workflow. ConfigCat's easy dashboard, reliable SDKs, and strong support make it simple for engineers to set up and manage feature flags. The platform fits right in with their React and Vue frontends, helping the team focus on what matters most: building great products and learning from users.

Eucalyptus is excited to keep expanding how they use feature flags. More experiments, smarter targeting, and even safer releases are on the horizon. Feature flag management is now a core part of their product growth strategy. With ConfigCat, the team is ready to keep innovating, keep learning, and keep users happy.

The Eucalyptus story shows how feature flag management can drive safe experimentation, faster launches, and smarter growth. If you want to help your team move faster, experiment with confidence, and keep your users happy, ConfigCat is ready to help.
