FaultMesh vs Steadybit

FaultMesh is a Kubernetes-native platform for testing system resilience through controlled failures, anomaly detection and automatic remediation. It injects latency, packet loss, pod kills, CPU stress and memory stress using Chaos Mesh CRDs. Real-time metric analysis can surface regressions, while rules and actions can heal systems automatically. The platform scores services across six dimensions and assigns L1–L5 maturity levels. It tracks SLO error budgets and supports multi-step chaos game days with checks between steps. Safety controls include blast-radius limits, dry runs, an error-budget gate, a background monitor and an instant kill switch. Teams can use managed SaaS or deploy a Kubernetes Operator in their own cluster, where data stays inside their perimeter. Security features include JWT and API-key authentication, role-based Admin, Operator and Viewer access, encryption in transit and an immutable audit trail. The maker describes controls as SOC 2-aligned, with formal certification on the roadmap, and data handling as GDPR-aligned. Starter is free for up to three services; Growth costs $49 a month billed per host, and a 14-day trial is available.

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.
