What Gremlin is

Gremlin is a chaos engineering platform that helps engineering teams find failure modes, fix them, and validate reliability before failures become outages. It injects faults into services, hosts, containers, and serverless workloads so teams can examine system responses. Blast-radius controls limit experiments, and the platform can automatically halt and roll back tests if issues arise.

Teams can sequence experiments into incident scenarios, schedule them, and use GameDay Manager to prepare, run, analyze, and store results. The platform also includes dependency discovery, standardized test suites and reliability scores, disaster recovery testing, detected risks, and organization-wide benchmarking. Documented integrations include Slack, Datadog, Dynatrace, AWS, Azure, Google Cloud Platform, Grafana Cloud k6, Jira, and custom webhooks. Supported environments include public clouds, Linux, Windows, Kubernetes, and on-premises deployments through self-hosted Private Edition. Gremlin states that it is SOC 2 Type II certified and encrypts data in transit with TLS and at rest with AES-256. The 30-day trial is free, requires no credit card, and does not auto-convert. Platform pricing is by custom quote per service, with agents, targets, and test volume sized during the pricing conversation.
