Facts

Purpose: Chaos Toolkit is a chaos engineering toolkit for developers to explore and test systems to discover weaknesses.chaostoolkit.org · 28 Sept 2026
Experiment format: Experiments can be declared and stored as JSON or YAML files for collaboration and orchestration like other code.chaostoolkit.org · 28 Sept 2026
Open API: The toolkit is extensible for systems through its Open API.chaostoolkit.org · 28 Sept 2026
Automation: The toolkit can be embedded in a CI/CD chain.chaostoolkit.org · 28 Sept 2026
License: The toolkit is open source under the Apache 2 license.chaostoolkit.org · 28 Sept 2026
Experiments: An experiment declares a steady-state hypothesis and probes to validate it, plus a method made up of actions and probes.chaostoolkit.org · 28 Sept 2026
Safety gate: If the steady state is not met, the method is not applied and the experiment must bail out.chaostoolkit.org · 28 Sept 2026

Installation: The installation guide provides Python setup instructions for macOS, Debian or Ubuntu, and Windows, and installs the CLI using pip.chaostoolkit.org · 28 Sept 2026
Extensions: After installing the CLI and core library, users can install extensions for different facets of chaos engineering.chaostoolkit.org · 28 Sept 2026
Deployment options: The offering page describes a standalone open source CLI; it distinguishes Reliably as a separate platform with SaaS, private SaaS and on-premises options.chaostoolkit.org · 28 Sept 2026
Community: The project invites contributions through issue reports, issue voting, project stars, community Slack, pull requests and extension proposals.chaostoolkit.org · 28 Sept 2026
Security practice: The contribution guide suggests contributor accounts enable 2FA to reduce security risks if an account is breached.chaostoolkit.org · 28 Sept 2026
