How Tinder Solves Complex Lottie Localizations with Server Driven UI
Article Summary
Tinder was manually creating 40+ localized Lottie animations for every campaign. Their solution? A clever architecture that reduced it to just one.
Tinder's engagement team faced a scaling nightmare: every animated campaign needed separate Lottie files for each locale. Jason Picallos and the team engineered a server-driven solution that leverages dynamic text layers, eliminating manual duplication across their global user base.
Key Takeaways
- Reduced from O(n) to O(1) complexity: one animation now serves infinite locales
- Dynamic text layers in After Effects enable runtime text replacement via Lottie SDK
- Four platform alignment required: After Effects, Insendio, backend, and mobile clients
- Team used time complexity analysis to evaluate real world scalability of solutions
- Cross functional collaboration between design, engineering, and product drove the breakthrough
Critical Insight
Tinder transformed Lottie localization from a manual, per-locale process into a single animation that dynamically adapts to any language through server-driven text overrides.
