As we enter the new year, we’re excited to share the Q4 updates from the LitmusChaos community. Over the past few months, the chaos engineering ecosystem and the LitmusChaos community have continued to grow steadily, driven by strong participation, thoughtful contributions, and meaningful collaboration across the globe.
This blog captures the highlights from October, November, and December, bringing together key project updates, community initiatives, contributor activities, and ecosystem developments around LitmusChaos. Our goal is to keep the community informed, celebrate the work happening across the project, and reflect on the collective progress made during the quarter.
About LitmusChaos
LitmusChaos is an open source chaos engineering platform that helps teams identify weaknesses and potential outages in their infrastructure by running controlled chaos experiments. Built on cloud-native principles, LitmusChaos enables teams to validate system resilience and proactively strengthen their DevOps pipelines against real-world software and infrastructure failures.
Started in late 2017 with a focus on simple chaos jobs for Kubernetes, LitmusChaos became a CNCF Sandbox project in 2020 and was promoted to a CNCF Incubating project in January 2022. Today, the project is maintained by contributors from multiple organizations across cloud-native vendors, solution providers, and end users.
LitmusChaos is used in production by organizations worldwide, including companies such as Adidas, FIS, iFood, Cyren, Intuit, Lenskart, Orange, as well as technology leaders like Red Hat and VMware.

The quarter emphasized security hardening, user experience improvements, and enhanced customization capabilities while maintaining the platform’s commitment to comprehensive chaos engineering tooling.
Innovation Spotlight: LitmusChaos MCP Server
October marked a watershed moment for LitmusChaos with the release of our Model Context Protocol (MCP) Server – a revolutionary integration that brings natural language interfaces to chaos engineering.
What is the LitmusChaos MCP Server?
The LitmusChaos MCP Server leverages Anthropic’s Model Context Protocol to enable AI assistants like Claude to interact directly with LitmusChaos through natural language. This integration transforms how teams approach chaos engineering by removing technical barriers and making resilience testing accessible to everyone.
Hacktoberfest 2025 (The Month of Open Source)
Hacktoberfest has always been special for LitmusChaos, and this year, we made it even bigger. The community came together to contribute to LitmusChaos and Litmus Docs, improving the project’s security, user experience, and accessibility with Litmus 4.0.
Here’s what we achieved together in October:
- GitHub Stars: 112+ new stars
- 23 new contributors to the Litmus repository
- 18 new contributors to the Litmus Docs repository
These numbers reflect the incredible passion our contributors showed throughout Hacktoberfest. A big shoutout to everyone who helped strengthen LitmusChaos through code, docs, and discussions!
In-Person Meetup Events
This quarter, we hosted 3 in-person meetups in Bangalore and Hyderabad.
LitmusChaos x Hacktoberfest Meetup – Bangalore (October 4)
We kicked off October with an incredible gathering, welcoming more than 130 attendees who came to celebrate open source and learn about chaos engineering. Check out a snapshot of the event here.
Hacktoberfest Hyderabad Meetup (October 11)
We hosted an additional Hacktoberfest meetup in Hyderabad that continued to bring together passionate open-source enthusiasts. You can see a short video of the event here.
Resilience and Chaos Testing Meetup (December 6)
The energy in the room was incredible for the first meetup that I’ve hosted around Chaos and Resilience testing, and the feedback from the community was amazing. You can read more about the event here.
