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.
| Feature | koigrid | CloudWatch Synthetics |
|---|---|---|
| Pricing | Flat rate | Per canary + Lambda runs |
| Setup | One API call / dashboard | Canary scripts + IAM + CloudFormation |
| Assertions | Status · latency · body · header | Scripted (Node/Python) |
| Alerts | Built-in (email + webhook) | CloudWatch Alarms + SNS |
| Lock-in | None (portable) | AWS-only |
| EU data residency | Yes | Region-dependent |

No scripting
Declare a check with assertions — no Puppeteer canary to maintain.
Alerts included
Email + webhook out of the box, no SNS wiring.
Flat rate, no lock-in
