The record

Purpose: Reliably helps teams build resilience engineering capability and deliver more reliable products by exploring operational risks and incidents.
Chaos engineering: The platform is built around an open-source chaos engineering platform based on Chaos Toolkit.
Experiment builder: The experiment builder simplifies creating experiments without learning a new language and provides more than 300 actions, including attacks and probes.
Experiment management: Users can import JSON Chaos Toolkit experiments, reuse custom templates, schedule executions, and review scores, freshness indicators, timelines, and dashboards.
Execution options: Plans can run as GitHub Actions, through Reliably-managed execution, using the CLI, in Docker, or as Kubernetes jobs or cron jobs.
Supported targets: The site lists AWS, Azure, Google Cloud, Kubernetes, Prometheus, and Spring among supported experiment targets.
Integrations: Documented integrations include Slack, Honeycomb, Dynatrace, Google Cloud, Grafana, OpenAI ChatGPT, pre-checks, safeguards, and auto-pause.
Integration behavior: Slack integration posts experiment activity to a channel in near real time, while Honeycomb sends traces using OpenTelemetry.
Secret handling: Reliably environments store variables and encrypted secrets used by the app, CLI, or GitHub workflows.
Safety controls: Pre-checks can stop an experiment before it starts and safeguards can interrupt it during execution when configured conditions are not met.
Open source: Reliably describes itself as open source and says its approach avoids lock-in.
Support: The pricing page lists email support on the paid plans, with Start, Scale, and Enterprise specifying weekday 9/5 CET support; Enterprise offers an optional support SLA.
Notable limits: Free includes one team member, 180 cloud execution minutes per month, a 10-minute cloud execution cap, and two weeks of data retention.
Company: The website says it is operated by ChaosIQ Limited, registered in England and Wales, with a registered office in London.
Price from: £40/mo
