Comparison

koigrid vs CloudWatch Synthetics

Uptime & synthetic monitoring — the simple, flat-rate replacement for CloudWatch Synthetics.

CloudWatch Synthetics runs canary scripts on Lambda — powerful but fiddly, AWS-only, and billed per canary plus Lambda runs. koigrid Checks gives you the same outcome (is my endpoint up, fast, correct?) with simple declarative checks, built-in alerting and a flat rate, EU-hosted.
