| Attack types | Documented assaults include latency, exceptions, application termination, memory, and CPU load. | The fault library includes CPU, process-killer, memory, certificate-expiry and GPU experiments. |
| Founded | 2004 | Gremlin says it was founded in 2016 by Kolton Andrus, who previously built fault injection at Amazon. |
| Integrations | The documentation describes using Unleash to control feature toggles and springdoc-openapi to show Chaos Monkey endpoints in Swagger UI. | Documented integrations include AWS, Azure, GCP, Jira and configurable REST webhooks. |
| Intended users | The project is focused on Spring Boot applications and aims to help test application behavior such as fallbacks, network latency, and service failures. | Gremlin describes its users as SRE and platform teams, and says financial services, retail, media, and B2B SaaS companies use the product. |
| Purpose | Chaos Monkey for Spring Boot tests Spring Boot applications by injecting failures during operation. | Gremlin helps engineering teams find failure modes, fix them, and validate reliability before failures become outages. |

Gremlin
Gremlin is a chaos engineering platform for engineering teams seeking failure modes and ways to 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, which can halt and roll back automatically 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. A 30-day trial is available without a credit card and does not auto-convert. Platform pricing is by custom quote per service; agents, targets, and test volume are sized during the pricing conversation.
