Datadog and Insomnia are often evaluated together by teams building out their reliability stack. Datadog (cloud-scale monitoring and security platform, founded 2010) is typically a fit for DevOps Teams, SREs, and Platform Engineers, while Insomnia (open-source rest, graphql, and grpc client for designing and testing apis, founded 2016) leans toward Developers, API Engineers, and QA Engineers. Both cover 4 of the same core capabilities, so the decision usually comes down to where they diverge.

No. It does a different job. API clients are built for developing and debugging requests. ObserveOne runs those same requests against production on a schedule, with assertions, alerting, and incident tracking on top.
