Gremlin vs Steadybit

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.

Steadybit is a chaos engineering platform for teams assessing reliability through planned testing. A no-code editor and templates support experiment design, while a live run view shows progress. Reliability Advice flags risks against best practices and suggests experiments and mitigations. Discovery identifies targets and metadata so teams can visualize and group system components. Tests can inject faults and check health across network, resource, and application layers. The platform supports scheduled experiments and blast-radius controls, with open source integrations for Kubernetes, AWS, Azure, GCP, Datadog, Grafana, Prometheus, Kafka, and RabbitMQ. Teams can also create integrations and custom actions with Extension Kits, ActionKit, and AdviceKit. Steadybit is available as SaaS and supports on-premises deployments, including air-gapped environments. Teams, roles, and fine-grained permissions help govern testing. Pricing is available on request; there is no free plan, but a 30-day free trial is offered. Professional has standard support during 9–5; Enterprise lists on-prem installation, SAML, audit logs, enterprise support, and tailored onboarding.
