Building the World’s leading travel search engine

As Kayak’s tech partners since 2008, we worked to build fully integrated native iOS & Android apps that extended their web-based experience for users on the go. We also improved its backend integrations, while our dedicated team of QA engineers work with them to provide end-to-end services.

As the world’s leading provider of aggregated travel search results including flights, hotels, car rentals, and deals, KAYAK constantly needs to build and improve its backend search technology.


KAYAK’s proprietary search technology depends on integrations with hundreds of providers and resellers around the world.


With over 50 million downloads from 30+ countries, 5 stars from over 140,000 happy travelers, and featured listings in the App Store, it’s easy to see why the apps won 10 Webby awards and were included in Wired Magazine’s ‘8 Best Apps for World Travelers.’


Wanderu is a ground travel metasearch engine and fare aggregator operating in 40 countries throughout North America and Europe and cited by prestigious media such as Fast Company, Forbes, Inc, and TechCrunch as a promising startup for a whole new generation of travelers. Since 2016 Arbisoft and Wanderu have partnered together to make it easy to manage road and rail bookings in a few clicks.


Arbisoft and Wanderu began a relationship focusing on mobile development. Wanderu turned to Arbisoft for help after they were unable to find iOS engineers with the right mix of engineering skills; so they incorporated our engineers into their in-house team and worked as a cohesive unit. Thanks to our mobile engineering team, Wanderu launched an iOS app enabling travelers to search online schedules, make bookings, and calculate fare for trips on the move. We also used Twisted, Treq, and Scrapy to integrate the Wanderu API with Carrier API which allowed the app to access listings from a wider range of road and rail carriers, along with writing custom code to allow location mapping.


Currently rated 4.5 stars, its app has been awarded “Favorite New App” by Time Magazine, “Best Travel App of 2015” by PC Magazine, and is listed in several top categories on the App Store–including Best New App and Featured Travel App. Our contributions have helped Wanderu extend its services to include a much bigger list of supported carriers, increasing its value to users and helps it differentiate itself in the travel management app startup space.
Our team of engineers — working closely with Wanderu’s internal team — has been able to create a substantial business impact by helping them bring on more partners at a faster pace. Arbisoft’s software has shortened the time between signing a partner and getting them live on the site, which is incredibly important for a new startup scaling to make big.
