Case Study: Cal.com achieves automated localization across 36 languages with Lingo.dev

Cal.com automates localization for 36 languages with Lingo.dev

Cal.com, an open-source scheduling platform, faced significant challenges with its internationalization efforts. Despite investing in translation agencies and crowdsourcing through a translation management system, the company was perpetually behind, with high costs and a constant drag on engineering velocity. To solve this, they turned to the vendor Lingo.dev and implemented its localization engine.

Lingo.dev's solution was a stateful translation API that integrated with Cal.com's CI/CD pipeline. This automated the process, delivering translations for 36 languages with every code push. The results were substantial: the engineering team no longer managed translation workflows, all languages stayed synchronized, localization costs were significantly reduced, and the process required zero handoffs. According to Lingo.dev, engineers stopped thinking about localization entirely as it became a seamless part of their infrastructure.
