APILens vs Datadog
API monitoring without a bill that scales with every host.
Datadog is a sprawling infrastructure-monitoring platform — priced and packaged for hosts, containers, and services you probably don't have. APILens is built for developers who want instant visibility into their Express or Fastify API, at a fixed price, with one line of code.
