How's Linear so fast? A technical breakdown

Article excerpt

Linear, the issue-tracking software, achieves its snappy performance through careful architectural choices: local-first data handling that keeps frequently-accessed information client-side, optimistic UI updates that predict server responses before they arrive, and efficient database indexing. The performance.dev analysis breaks down how these techniques, common in modern apps but rarely implemented as thoroughly, combine to deliver sub-100ms response times even on slower networks. Linear's engineering priorities reveal a discipline often absent in heavier project management tools, where every keystroke and page transition feels instantaneous rather than laggy.
