| Integrations | FIS can be accessed through the AWS Management Console, CLI, SDKs, CloudFormation, and HTTPS API, and its APIs can be used in CI/CD pipelines and custom tooling. | Documented integrations include Slack, Honeycomb, Dynatrace, Google Cloud, Grafana, OpenAI ChatGPT, pre-checks, safeguards, and auto-pause. |
| Purpose | AWS FIS runs fault injection experiments on AWS workloads to help teams improve application performance, observability, and resilience. | Reliably helps teams build resilience engineering capability and deliver more reliable products by exploring operational risks and incidents. |
| Safety controls | Experiments can use tags to select targets and CloudWatch alarms or other tools to stop an experiment when conditions are met. | Pre-checks can stop an experiment before it starts and safeguards can interrupt it during execution when configured conditions are not met. |

Reliably
Reliably helps teams examine operational risks and incidents as part of resilience engineering. Built around an open-source chaos engineering platform based on Chaos Toolkit, it offers an experiment builder with more than 300 actions, including attacks and probes. Teams can import JSON Chaos Toolkit experiments, reuse templates, schedule runs, and review scores, freshness indicators, timelines, and dashboards. Experiments can run as GitHub Actions, through Reliably-managed execution, with the CLI, in Docker, or as Kubernetes jobs or cron jobs. Listed targets include AWS, Azure, Google Cloud, Kubernetes, Prometheus, and Spring. Pre-checks can prevent a run from starting; configured safeguards can interrupt one during execution. Environments store variables and encrypted secrets for the app, CLI, or GitHub workflows. The Free plan is free and limits teams to one member, 180 cloud execution minutes per month, a 10-minute cloud execution cap, and two weeks of data retention. Start costs £40 a month, billed monthly.
