Our Lambda functions process 50M events a month but we have no idea which users are behind them. Traditional analytics assumes a persistent server that we do not have.
Person-Level Analytics for Serverless Architectures
KISSmetrics works in stateless environments. Track events from Lambda, Edge Functions, and Workers with a lightweight client that adds zero cold-start overhead.

Sound familiar?
Serverless architectures changed deployment, but analytics tools have not caught up. Traditional server-side SDKs assume persistent processes with in-memory state, connection pools, and graceful shutdown hooks. In a Lambda function that spins up, processes a request, and dies in 200ms, those assumptions are liabilities. Connection pools never warm up, background flush timers never fire, and events are lost when the execution context is frozen.
KISSmetrics provides a serverless-native client designed for ephemeral execution environments. It uses synchronous HTTP sends (or configurable async with waitUntil support), has zero initialization overhead, and does not rely on background processes or persistent connections. Every event is delivered before your function returns.
Whether you are running AWS Lambda, Cloudflare Workers, Vercel Edge Functions, Deno Deploy, or Netlify Functions, KISSmetrics captures events reliably. Combined with frontend tracking, you get unified person timelines that span client-side interactions, edge logic, and serverless backend processing - all attributed to the same user.

“We process 12M events/day through Lambda functions. The previous analytics SDK added 400ms to every cold start. KISSmetrics adds zero. Our P99 latency actually improved after adding analytics.”
