Wise Engineering As of the financial year 2025, Wise supports 15.6 million active customers, moving approximately GBP 36 billion across borders each quarter. Approximately 65% of our transfers arrive instantly, and our Wise Platform facilitates payments for banks, financial institutions and enterprises globally. This success is driven by our technology-first approach, robust architecture, and dedicated engineering teams.

These teams are empowered to innovate and make decisions independently, fostering transparency, trust, and collaboration. This article follows our Tech Stack 2022 to cover the most recent improvements in Wise's tech stack that enable us to achieve our mission of money without borders -- instant, convenient, transparent and eventually free. Moving money with WiseOur web and mobile applications Our web applications are built using CRAB (a Wise-specific abstraction on top of the popular Next.js framework) and comprises of 40 distinct apps, each handling specific product functions making deployments safer and more manageable. One of the biggest changes has been in our testing methodology. We've adopted Storybook for visualising individual React components during development. Storybook pairs really well with Chromatic which captures snapshots after each change and can highlight the visual differences in the component. These snapshots are very effective for catching visual regressions during code changes which helps us prevent bugs from reaching our customers. Wise mobile app: faster, smarter, and more efficient Our iOS engineers have upgraded our infrastructure by migrating 250+ Xcode modules from Xcodegen to Tuist and switching from Cocoapods to Swift Package Manager (SPM), unlocking improvements in caching for builds. The team also improved flexibility, reducing zero-change build times from 2
