ColdStartIQ

ColdStartIQ is a web app that pinpoints why your serverless and edge functions feel slow in real user traffic, then tells you exactly what to change. It ingests traces and logs from common stacks, detects cold-start events, and correlates them with deploys, regions, memory settings, dependency size, and upstream calls. You get a “cold-start budget” per route/function, a ranked list of the worst offenders, and a replayable test harness to validate improvements before shipping. The product focuses on pragmatic wins: package slimming, init-time hotspots, connection reuse, runtime choice, and region placement. It also tracks the cost impact of fixes so teams don’t trade latency for runaway spend. This is not a generic APM clone; it’s a narrow tool aimed at one of the most stubborn serverless pain points.
