Steadybit vs Toxiproxy

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.

Toxiproxy is a free, open-source TCP proxy for testing how software responds to network and system problems in development, testing, and CI. Applications route test connections through it, then users change connection behavior through an HTTP API or command-line interface. Built-in toxics can add latency or jitter, restrict bandwidth, delay socket closure, time out or reset connections, slice TCP data, limit transmitted data, or drop packets. Settings support deterministic connection changes as well as randomized chaos. The API manages proxies and toxics, resets proxies, and returns version information and Prometheus-compatible metrics. It listens on port 8474; configuring a proxy with listen port 0 assigns an ephemeral port. Client libraries are listed for Ruby, Go, Python, .NET, PHP, Node.js, Java, Haskell, Rust, and Elixir. Installation options include Linux packages and binaries, Homebrew and MacPorts, a Windows download, a container image, and building from source with Go. The project identifies its license as MIT. Its HTTP API is unauthenticated by default, though bearer-token authentication is supported.
