Gremlin review
A broad managed chaos platform for controlled failure testing across modern infrastructure.
Reviewed by iTechGuides Editors · Editorial team · Updated Nov 2026
Gremlin is a chaos engineering and reliability platform for SRE, platform, and engineering teams. It supports controlled fault injection across services, hosts, containers, Kubernetes resources, and serverless workloads. Teams can run repeatable experiments, combine them into scenarios, schedule recurring tests, and use target selectors, percentage-based impact, exclusions, and blast-radius graphs to control scope. Web, Windows, Linux, API, and self-hosted options support hybrid environments.
The published plans show a quote-based commercial model. Gremlin Platform includes dependency discovery, fault injection and scenarios, test suites, reliability scores, disaster recovery testing, detected risks, and organization-wide benchmarking and reporting. Gremlin Foresight AI adds supervised resilience engineering agents, recommended remediation, closed-loop verification, MCP server, API, chat, and LLM skills, with unlimited team members. Professional Services covers a Reliability Baseline, Peak Readiness Campaign, Continuous Reliability Roadmap, and handoff training. Fault Injection is available separately as an enterprise suite. A 30-day trial requires no credit card and does not auto-convert.
Its standout strength is the connection between controlled failure, safety controls, and reliability analysis. Network experiments cover blackhole, latency, packet loss, and DNS failures, while health checks can halt tests when services become unhealthy. Dashboards, reports, service scoring, REST API access, and a command-line interface support repeatable operational programs. Integrations include AWS, Azure, Google Cloud Platform, Slack, Datadog, Dynatrace, Jira, Grafana, New Relic, PagerDuty, Prometheus, and webhooks. Gremlin suits organizations that need managed, multi-environment chaos engineering with governance and reporting. Teams seeking a free product or transparent self-serve pricing should consider a different option.
