Case Study: Linktree achieves 99.999% uptime and scalable global performance with Fastly

How Linktree scaled to support 4 million new users in 3 months

Linktree, the Australian SaaS startup behind the “link in bio” category, was growing fast and needed a better way to handle security and scaling challenges. As views approached nearly 1 billion per month and signups surged, Linktree turned to Fastly for an edge cloud platform and next-gen WAF to improve protection, reliability, and global performance.

Fastly implemented its Cloud WAF and CDN to help Linktree block abusive traffic, support edge-based security rules, and scale more efficiently. The results were immediate: Linktree detected and stopped a fake-account bot within two minutes, boosted uptime from 96% to 99.999%, and supported 4 million new users in three months while keeping profiles fast and reliable worldwide.
