What are Free Chaos Engineering Tools?

Chaos engineering tools are software programs designed to simulate and test potential failures in a system. These tools allow engineers to identify weaknesses and potential points of failure in their systems before they occur in real-world situations. They often use techniques such as fault injection, randomization, and controlled disruptions to intentionally introduce chaos into a system. The goal of these tools is to help organizations build more resilient and reliable systems by exposing vulnerabilities and allowing for proactive problem-solving. Many companies use chaos engineering tools as part of their regular testing and development processes to continuously improve their systems' stability. Compare and read user reviews of the best Free Chaos Engineering tools currently available using the table below. This list is updated regularly.

    Harness

    Harness

    Harness

    Use each module independently with your existing tooling or use them together to build a powerful unified pipeline spanning CI, CD, STO, SRM and Feature Flags with metadata enhancing cloud cost management. AI/ML are at the heart of every Harness module. Our algorithms verify deployments, identify test optimization opportunities, make cloud cost optimization recommendations, restore state on rollback, assist with complex deployment patterns, detect cloud cost anomalies, and trigger a bunch of other activities. After a deployment, sitting around staring at logs and dashboards sucks. Harness analyzes the logs, metrics, and traces from your observability solution and automatically determines the health of every deployment. When a bad deployment is detected, Harness can automatically rollback to the last good version.
