Over the past two years, our UX team has experimented with AI across four disciplines: UX Copy, Localization, Research, and Product Design. What started as scattered manual processes has evolved into an integrated, AI-native workflow where our team orchestrates and AI executes. Three Eras of UX Copy Our UX Copy discipline evolved through three distinct eras. In the pre-AI era, we handled everything manually — iterating on copy in design and documentation tools, creating localization keys one by one (each requiring a description, key name, character limit, and screenshot), and requesting…
Introduction About six years ago, our mobile automation setup was showing its age. It was a small, homegrown framework that had worked “well enough” for a long time, until we tried to upgrade Java and a few core dependencies. That’s when things started breaking in ways we couldn’t reasonably patch around. The framework simply wasn’t built to move forward. Rather than trying to keep it alive with one off fixes, one of our engineers used the moment to start a learning project with Appium 1. The goal wasn’t to replace everything overnight, it was to explore whether we could build something…
It’s a scenario developers relate to a little too well. The product manager always comes with more and more feature requests. They also want to release fast by giving a tight deadline. While you, as a developer, care more about stability, performance, and maintainability of your application. This tension can easily turn into friction. But what if there was a way to align both sides; using data instead of relying on opinions? We are betting on a practice called Service Level Objectives (SLO). Can it stop the fight? 🤔 Why does conflict happen? ⚖️ The root of many developer vs product manager…
Mob programming often sparks hot takes. “It’s counter‑productive.” “One person could do it faster.” “Why waste five people on one keyboard?” If that’s what it looks like in your head—one senior typing while others half‑listen—that wasn’t mob programming. Real mob programming is structured collaboration that turns a team’s combined attention into forward motion. What is mob programming? Before I get into the use cases, here’s a clear definition and a few basic ground rules—consider it a TL;DR of sorts . “All the brilliant minds working on the same thing, at the same time, in the same space.” —…
Between 2023 and 2025, our approach to artificial intelligence shifted from isolated experimentation to company-wide integration. This transformation has delivered measurable productivity gains, accelerated innovation, and fostered a culture of knowledge sharing. As our AI Ambassador group celebrates its two-year anniversary in October 2025, we reflect on the data, the challenges, and the strategic direction for AI at trivago. Empowering our 700 talents to have the impact of 7,000 Ioannis Papadopoulos, our new Chief Technology Officer, set the tone: trivago’s vision is to empower its almost…
Our first browser extensions When doing exploratory testing on a web application, the nature of activities involves discovering things and not repeating the same patterns. However, there might be aspects that could be improved by specific tools without trespassing into the realm of test automation. Can coding skills help testing activities, beyond the somewhat obvious case of automated tests? In the trivago QA team we asked ourselves this question, trying to find solutions to make some testing processes less cumbersome and save time while maximizing focus. Almost 10 years ago, we started…
How I buy (learn) tech from Cloud Platform teams and sell (teach) solutions to Product Engineering teams Introduction If you are a Developer or a Product person, you might have this feeling of achievement when you work on a specific product. When it’s launched successfully in the market, you see people start using something built by you. You become proud because your hard work results in something that is helping many people to achieve their tasks. This is a rewarding feeling for many of us! But to go back a little, after working on a product, is it you who is promoting this to the mass…
Price comparison is one of the key value propositions of trivago, and in doing so, we handle billions of prices everyday to provide our users with the most accurate and up to date price as possible. We can leverage this enormous amount of historic price data to provide price context for our users in a scalable and fast way. Why do we need aggregated price data? As we handle billions of prices everyday, aggregating them in real time to provide, for example, the average price for Berlin for next month, would add an extra load into our application and it would not be beneficial for the user…
Modern frontend engineering is a collaborative effort of many people with different talents and expertise. Over the years, a team working together can continuously refine their ways of working, so that the different contributions fit together seamlessly and each step in the production process is in sync with the next one. Read about our team structure, our A/B test setup, and about what makes our QA team so special. At trivago, our frontend team is a vibrant group of about 80 people working together in squads led by product managers. With close collaboration among product managers, designers,…

Introduction Over the last year trivago refactored the existing GraphQL monolith and moved to a microservice architecture, in what is also known as a federated setup. Federated GraphQL, as championed by Apollo, represents a significant shift in how companies architect and scale their GraphQL ecosystems, especially when transitioning from monolithic designs to microservice-based architectures. In a federated setup, each microservice maintains its own GraphQL schema, relevant to the domain it serves. These individual schemas are then seamlessly stitched together into a unified gateway. This…
