VisitFaultMesh vs Gremlin
What both publish
| Fact | FaultMesh | Gremlin |
|---|---|---|
| API | A single REST gateway exposes endpoints for authentication, experiments, game days, incidents, remediation, scoring, topology and licensing. | The public REST API uses the base URL https://api.gremlin.com/v1 and has an OpenAPI specification. |
| API authentication | Interactive clients use JWT bearer tokens while agents and CI can use long-lived API keys. | API requests can authenticate with bearer tokens or user and team API keys, with MFA-supported login flows. |
| Compliance | FaultMesh describes its controls and processes as SOC 2-aligned, with formal certification on the roadmap, and its data handling as GDPR-aligned. | Gremlin reports ISO 27001/27017, PCI DSS Level 1, SOC 1/2/3 and SOC 2 Type II coverage for its hosted environment. |
| Fault injection | The platform injects latency, packet loss, pod kills, CPU stress, memory stress and other faults through Chaos Mesh custom resources. | Experiments can target services, hosts, containers and serverless workloads, with automatic halt and rollback controls. |
| Purpose | FaultMesh injects controlled failures, detects anomalies in real time, remediates automatically and scores system resilience on a Kubernetes-native platform. | Gremlin helps engineering teams find failure modes, fix them, and validate reliability before failures become outages. |
| Safety controls | Experiments support dry runs, blast-radius limits, an error-budget gate, timeout monitoring and an organisation-wide kill switch. | Gremlin supports blast radius controls and automatic halt and rollback of experiments if issues arise. |

Pick FaultMesh if…
Starter is described for small teams beginning chaos engineering, while Growth suits teams making it routine. Enterprise is aimed at organizations that want to run FaultMesh inside their own perimeter.
Pick Gremlin if…
Gremlin is aimed at SRE and platform teams, including teams in financial services, retail, media, and B2B SaaS. It also suits teams that need self-hosting rather than SaaS.
