The Checkly team has developed a new feature called the "Checkly Agent" which is a container-based tool that runs API and browser checks in users' infrastructure, eliminating the need for another monitoring setup. This agent connects to the Checkly cloud to define check intervals, store results, and alert when things go wrong. It provides private locations where users can run tests and receive alerts without having to set up separate monitoring infrastructure for their internal applications. The agent is designed to be stateless, scalable, and ephemeral, allowing users to add and remove it as needed, and can even run redundancy checks with multiple agents in the same infrastructure.
