Alternatives to Reliably

{"intro": "Reliably gives teams a resilience engineering workspace for designing, running, and reviewing chaos experiments. Its builder offers more than 300 actions without requiring a new language, while JSON imports, reusable templates, schedules, scores, freshness indicators, timelines, and dashboards support ongoing work. Runs can use GitHub Actions, the CLI, Docker, Kubernetes jobs, cron jobs, or Reliably-managed execution. Pre-checks and safeguards can stop or interrupt experiments, and supported targets include major clouds, Kubernetes, Prometheus, and Spring. It runs on Linux, macOS, Windows, web, and self-hosted deployments.\n\nReaders may still want a free project, narrower Kubernetes focus, deeper network simulation, or automatic remediation. Reliably’s Free plan permits one team member, 180 cloud execution minutes monthly, a 10-minute cloud-run cap, five custom experiments, one template, and two weeks of retention; paid plans start at £40/mo. Compare those limits with each alternative’s experiment format, fault coverage, execution methods, safety controls, deployment model, integrations, and monitoring. The better choice depends on whether you need a managed workspace or direct control over code, clusters, proxies, or service-level objectives.", "rows": [{"ref": "sw:chaos-toolkit", "name": "Chaos Toolkit", "best_for": "Developers defining chaos experiments as code", "pricing": "Free plan", "key_difference": "Chaos Toolkit is a free, code-oriented open-source toolkit with JSON or YAML experiments and an extensible Open API.", "choose_when": "Choose it when you want portable experiment files, CI/CD embedding, and broad integrations without Reliably’s paid workspace."}, {"ref": "sw:chaosblade", "name": "ChaosBlade", "best_for": "Cloud-native teams running varied Kubernetes scenarios", "pricing": "Free plan", "key_difference": "ChaosBlade combines a CLI with ChaosBlade-Box, offering resource, application, and Kubernetes scenarios plus Helm deployment and Prometheus integration.", "choose_when": "Choose it when Kubernetes-native execution methods and a unified experiment interface matter more than Reliably’s experiment review workspace."}, {"ref": "sw:faultmesh", "name": "FaultMesh", "best_for": "Teams needing automated remediation and resilience scores", "pricing": "Free plan; paid from $49/mo; 14-day trial", "key_difference": "FaultMesh adds real-time anomaly detection, automatic healing, six-dimension resilience scoring, SLO tracking, and managed or in-cluster deployment.", "choose_when": "Choose it when automated remediation, maturity scoring, and error-budget gates outweigh Reliably’s broader execution options."}, {"ref": "sw:krkn", "name": "Krkn", "best_for": "Kubernetes operators exploring many scenario types", "pricing": "Free plan", "key_difference": "Krkn focuses on Kubernetes failures with more than 20 scenarios, PromQL SLO validation, Cerberus health signals, and Krkn-AI experiment selection.", "choose_when": "Choose it when Kubernetes scenario breadth, cluster health monitoring, and objective-driven experiment discovery are priorities."}, {"ref": "sw:toxiproxy", "name": "Toxiproxy", "best_for": "Testing network behavior in development and CI", "pricing": "Free plan", "key_difference": "Toxiproxy is a TCP proxy for manipulating connections over HTTP, with deterministic or randomized network conditions rather than Reliably’s broader experiment platform.", "choose_when": "Choose it when you need controllable latency, packet loss, bandwidth, resets, or timeouts around test connections."}, {"ref": "sw:chaos-mesh", "name": "Chaos Mesh", "best_for": "Kubernetes teams orchestrating diverse infrastructure faults", "pricing": "Free plan", "key_difference": "Chaos Mesh uses Kubernetes resources and a dashboard to schedule workflows across pod, network, cloud, physical-machine, JVM, and other fault types.", "choose_when": "Choose it when Kubernetes-native workflows, recurring schedules, and wide fault coverage suit you better than Reliably’s hybrid platform."}, {"ref": "sw:gremlin", "name": "Gremlin", "best_for": "Organizations wanting managed chaos with GameDays", "pricing": "Pricing on request; 30-day trial", "key_difference": "Gremlin injects faults across services, hosts, containers, and serverless workloads, with GameDay Manager, automatic halt and rollback, and Private Edition.", "choose_when": "Choose it when you need coordinated incident scenarios, enterprise integrations, or self-hosted Gremlin rather than Reliably’s freemium plans."}]}
