REAL-WORLD ENGINEERING AT CURSOR: BUILDING FOR 100X GROWTH

Summary from the TLDR AI newsletter

Cursor cofounder Sualeh Asif reveals how the two-year-old startup handles 1M+ queries per second without storing any code on its servers, using Merkle trees for secure indexing. The team survived 100x growth by switching databases during outages (Yugabyte → PostgreSQL → Turbopuffer in hours) and built Anyrun, their Rust-based orchestrator, to manage thousands of GPUs.
