October has been one of the most exciting and eventful months for the LitmusChaos community. With Hacktoberfest 2025 in full swing, we went all in, from hosting community-driven events to supporting contributors, shipping releases, and celebrating amazing open-source contributions.
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
- LitmusChaos Issues: 42 created → 27 closed (PRs merged), 15 in progress
- Litmus Docs Issues: 34 created → 31 closed (PRs merged), 3 in progress
- New Contributors
- 23 new contributors to LitmusChaos
- 18 new contributors to Litmus Docs
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!
Release Spotlight: LitmusChaos MCP Server
One of the biggest highlights of October was the release of the LitmusChaos MCP (Model Context Protocol) Server, a major step toward making Chaos Engineering more accessible and intelligent.
The Litmus MCP Server allows users to interact with chaos experiments using natural language, bridging the gap between developers and automation. Imagine simply asking, “Run a pod-delete experiment on the checkout service,” and seeing it happen seamlessly — that’s the power MCP brings to the Litmus ecosystem.
Adoption Continues to Grow
LitmusChaos continues to see strong adoption within the cloud-native ecosystem.
October Installation Trends:
- Mid-month spike: around 5.2K installations (Oct 6–7)
- End-of-month range: roughly 3.8K–4K installations
- Average daily installations: around 3.5K–4K
It’s heartening to see teams worldwide continue to adopt ChaosCenter to build more resilient systems.
New Blog of the Month
We published a new blog this month:
