Integrations with other Harness modules

In addition to the above features, HCE integrates with these Harness modules:

HCE free plans

Harness offers a free hosted LitmusChaos if you are trying to get started with LitmusChaos or Chaos Engineering in general. The HCE free plan is a free-forever plan that has features equivalent to LitmusChaos, and also bundles Harness platform features such as RBAC and hosted logging— all for free.

Sign up at to get started with a free plan for either the hosted HCE or the hosted LitmusChaos.


The HCE free plan replaces New sign ups are not being accepted at Users on that platform are advised to move to the HCE free plan before August 31, 2023. For free support on migration, contact Harness Support.
