Gremlin is a SaaS solution for organizations to conduct chaos experiments and help test the resilience of their systems. It comes with a series of failure attacks — including resource, network and state failures — that can be run ad hoc or on schedule and require minimal setup (especially for Kubernetes users, who can run Helm to install Gremlin). The Gremlin client also has a nice web-based user interface, which makes it easy to execute and manage chaos experiments.
