To scale, Toss needed to avoid overloading its front-end teams.As internal tooling demands across departments grew, building admin dashboards and back-office apps in React became inefficient. Toss looked for a low-code platform that enabled backend developers and cross-functional teams to create internal apps without slowing down the core product roadmap. ‍
