Open source
Chaos Monkey
Netflix's instance killer. The original, tied closely to Spinnaker.
⚠ Comparison
Chaos engineering tools, honestly compared
The main chaos engineering tools are Chaos Monkey, Chaos Mesh, LitmusChaos, Toxiproxy, AWS Fault Injection Service, Azure Chaos Studio and Gremlin. Most are building blocks you run yourself; a managed service adds scheduling, guardrails and reports. Here is where each one fits, including us.
Open-source building blocks
Open source
Chaos Mesh and LitmusChaos
CNCF projects for Kubernetes chaos. Powerful, and yours to run and upgrade.
Open source
Toxiproxy
Network fault proxy for latency, timeouts and dropped connections.
Open source
k6 and stress-ng
Load and resource stress. Great primitives, no orchestration.
Managed services
Cloud-native
AWS Fault Injection Service
Strong inside AWS; does not cover other clouds or on-prem.
Cloud-native
Azure Chaos Studio
Strong inside Azure; same single-cloud trade-off.
Commercial
Gremlin
Established chaos engineering platform with a broad feature set.
Us
Oh My GDaaS
GameDays as a service: open-source lineage, multi-cloud, guardrails, scheduling and reports, running in minutes.
How to choose
If you have a platform team with spare quarters, open source gives you full control. If you are all-in on one cloud, its native tool is a fine start. If you want GameDays running this week across everything you own, without maintaining the plumbing, that is what we built.
