Introducing Switchback Testing on Eppo: An Intuitive Tool for Complex Marketplace Experiments
Learn more
When you’re building software, enabling experiments or feature flags in production shouldn't leave you second-guessing if your implementation is correct. Integrating your event logging with your experimentation and flag tools can feel like a chore, especially if your team doesn’t already have the right infrastructure. And even with tools in place, how do you confirm everything works exactly as intended? Enter Eppo’s new Event Logger.
We designed our Event Logger to make implementation faster, easier, and stress-free, giving you visibility into the data moving through your system. Whether you’re spinning up a proof-of-concept (PoC) or refining your production setup, this tool streamlines the process of launching experiments while ensuring nothing slips through the cracks. It’s not about reinventing how logging works but solving a fundamental question instead: How can I be confident this is set up correctly? With Eppo, you’ll capture and surface logs in a way that makes them auditable, verifiable, and actionable.
The goal? Get back to shipping impactful features while we take the guesswork out of setup and validation.
It’s never just about logging events. It’s about knowing your feature flags and experiments are running exactly as designed. The Event Logger makes it easy to verify and audit your implementation, removing uncertainty so you can focus on creating real value.
Here’s how it helps you stay ahead:
Most tools are pipes that send events to other places as needed. Eppo takes it a step further, ensuring you can track down issues, verify that things are working as expected, and maintain trust in your experiments and features. It’s not just about collecting data, it’s about giving you the confidence to trust it.
Previously, managing assignments in Eppo required a few extra steps, especially during PoCs. Here’s the high-level process teams followed to get started:
Each of these steps required coordination between teams, custom development work, and potential delays.
We built the Event Logger to make your life easier. Instead of wrangling integrations and custom queries, Eppo’s Event Logger handles all the heavy lifting for you. Now, you can log assignments directly from Eppo experiments without the extra complexity.
It’s the same trusted Eppo experience but with way less upfront work.
Faster proof-of-concept launches. Less friction getting started. And more time to spend on your experimentation strategies instead of integration roadblocks.
Every team approaches logging assignments differently, and Eppo is designed to adapt to your unique needs. Whether you opt for Eppo's built-in Event Logger or integrate your own solution, like a CDP or an in-house solution, the decision isn’t about one being universally superior. It’s about choosing the approach that aligns best with your situation.
Whatever path you choose, Eppo adjusts to meet your needs. Our support for external logging solutions remains robust, but if speed and simplicity are top priorities, Eppo’s Event Logger can help you hit the ground running.
Unlike traditional loggers, Eppo’s Event Logger is purpose-built for experimentation. It doesn’t try to be a full CDP or a sprawling behavioral analytics platform. Instead, it delivers exactly what you need to get experiments rolling quickly and reliably.
Experimentation should be empowering, not exhausting. With Eppo’s new Event Logger, we’re removing barriers, cutting down on setup time, and giving you the tools to focus on what matters most and make data-backed decisions with confidence.
