Reimagining Feature Flags: How Eppo Eliminated the Engineering Burden

Stop us if this sounds familiar: your data, product, or marketing teams are eager to run more experiments and ship features faster with a new experimentation platform,
but you can already see it coming: a flood of additional engineering hours spent managing feature flags. We’ve seen this pattern play out repeatedly, so we partnered with our users to completely redesign Eppo’s feature flag management experience.

In conversations with dozens of teams (not just engineers), we heard the same story: experimentation programs often place a heavy, ongoing burden on engineering. The proliferation of feature flags creates complexity that only engineers can untangle.

Common Complaints From Engineers

  • Overwhelmed by cluttered UIs that mix routine tasks with rarely-used options.
  • Stressed about turning on flags in production without knowing the exact impact
  • Swamped by constant requests to create or manage flags for other teams.
  • Frustrated by training new team members on complicated flagging solutions.
  • Concerned about needing to manage separate flags or even flagging solutions for software rollouts and experimentation.

Solving these complaints has led to an approach that makes it easier than ever to create flags, visualize their scope and impact, and ensure stress-free launches every single time.

Our Solution: Effortlessly Intuitive Workflows

The redesigned experience directly addresses these pain points, creating an intuitive interface that makes feature flag management easier for everyone. Engineers can implement the flags needed for feature releases and error rollbacks, all while data, product, and marketing teams have the tools needed to easily modify flags for experimentation when needed.

1. Simplified Flag Creation

Transforming complexity into clarity:

  • Flags now start with just a name, we handle the key generation and apply smart default settings.
  • On/off flags are the default, making the most common use case the simplest one.
  • Advanced features, like randomization and targeting rules, stay accessible but discreet.

This simplified model frees up engineers to tackle more complex challenges, instead of spending hours handling routine toggle requests.

2. Chrome Plugin for Feature Management

Optimize your experimentation workflow and deliver smooth feature rollouts with Eppo Developer Tools. It is a robust browser extension designed to help you manage and analyze experiences driven by Eppo Feature Flags. 

With this tool, you can:

  • Quickly search for and toggle feature flags to test different variations with ease.
  • Recreate user-specific experiences to QA and troubleshoot effectively.
  • Get deeper insights into how Eppo flags are shaping your application's behavior.

3. Global Environment View

Our global environment view is one of the most significant upgrades to your feature flagging workflow.

  • See every rule across all environments at a glance.
  • The ability to create and edit rules that apply to multiple environments, ensures rules always stay in-sync. No more worrying about duplicating rules or updating them in multiple environments.
  • Enjoy clear visualizations that immediately indicate flag behavior without clicking through multiple screens.

This unified perspective enhances clarity, reduces errors, and ensures consistency across environments.

4.  Scheduled Rollouts and Phased Deployments

Take control of your feature releases with powerful scheduling capabilities that reduce risk and increase confidence. 

  • Create automated rollout schedules for gradual, controlled feature releases
  • Set precise phases with specific dates, times, and traffic percentages
  • Easily modify schedules as priorities shift

This structured approach to deployment allows DevOps teams to safely introduce features to production, monitor performance metrics in real-time, and make data-driven decisions about wider rollouts.

5. Record any action your users perform for even deeper insights

Eppo’s Track API allows you to easily track every click, page view, or purchase. This is then automatically processed and loaded into your data warehouse, ensuring engineering, data, product, and marketing are all referencing the same information.

  • Discover where users might get stuck, what features they love, and what drives them to come back.
  • Customize their experience based on those learnings — send personalized messages or recommend features they’d find useful.
  • Keep everything consistent across all your different tools (analytics, CRM, marketing platforms, etc.).

This enhanced visibility and insight builds confidence across teams, allowing teams to experiment more effectively and immediately apply their learnings.

Keeping the Power, Losing the Clutter

While we’ve simplified the user experience, we’ve preserved all the advanced functionality that experts rely on, giving your company the best of both worlds: a reliable feature flagging solution with enterprise-grade reliability, redundancy, and low latency while fostering the experimentation culture that powers today’s most successful companies.

  • Advanced randomization options stay accessible in a logical, organized way.
  • Experiment analysis integration remains seamless, whether using randomized flags or optional configurations.
  • Sophisticated targeting rules can be built through an intuitive rule editor that doesn’t sacrifice complexity.

Before and After: A Streamlined Redesign

Feature flags that act to simply turn app features on and off used to require several steps that could be time-consuming or confusing. Now, all you need to do is name the flag, and the system takes care of the rest by applying smart defaults. For Eppo and flagging experts, we’ve kept all the advanced tools for more complex tasks, but they’re thoughtfully organized to avoid unnecessary clutter for others.

The Future of Feature Flag Management at Eppo

Eppo’s redesigned experience is just the start. Here’s a glimpse of what’s coming next to make feature flags even more powerful and accessible:

  • Real-time monitoring and telemetry - See how users are receiving variations in real-time, detect unexpected behavior immediately upon activation, and break down variation traffic at a glance for a detailed distribution snapshot.

  • Enhanced logging integrations - Easily connect feature flag data with tools like Datadog and Sentry.

  • Granular assignment breakdowns - Understand flag evaluations across every environment with precision.

Try It Yourself Today

We’ve created a platform without the constant tug-of-war between effective feature flagging and scalable experimentation. Product managers can confidently toggle features without waiting on engineering, data scientists can run precise, impactful experiments, and marketers can validate ideas in real-time, all while engineers have a low-maintenance and high-observability flagging solution.

We see high-performing teams do this every day by leveraging Eppo’s feature flags. Built for seamless collaboration and trusted by cross-functional teams, we empower organizations to innovate faster, experiment smarter, and grow together.
