Figma has published a detailed account of how it built an in-house Redis proxy service called FigCache, replacing a fragmented caching stack that had become a liability for site availability. The system, described in a post by Kevin Lin, has been in production since the second half of 2025 and has delivered what the company describes as six nines of uptime across its caching layer.
