StackStorm is still under active development. We welcome community feedback, and encourage contributions. Here’s our plans for the next releases.


This is a roadmap. It represents our current product direction. All product releases will be on a when-and-if available basis. Actual feature development and timing of releases will be at the sole discretion of the development team. This roadmap does not create a commitment to deliver a specific feature. Contents are subject to change without notice.

If there’s something you really need, remember: this is Open Source. Write and contribute the feature. Pull Requests are open to anyone.


  • Output Schema: Allow action/runner output schemas to cover all output types, not just JSON objects.

  • More will be added to the roadmap for 3.8. So, stay tuned!

Monitor the master branch to see how we’re progressing.


Here’s some more nice things on our list that we haven’t scheduled yet:

  • Python ChatOps: Convert ChatOps backend to Python

  • ChatOps: Support RBAC.

  • K8s/HA: Graduate K8s Helm chart from beta to stable.

  • Workflow runtime graph: Runtime view of workflow execution in st2flow for Extreme Workflow Composer.

  • Workflow dry run: Ability to run unit tests on orquesta workflows for Extreme Workflow Composer.

  • SSO: Support SSO with SAML2 for Extreme Workflow Composer web UI (beta).

  • Job Scheduling: Job scheduling for ad-hoc jobs.

  • Datastore viewer/editor: Datastore viewer/editor at web UI.

  • History and Audit service: History view with advanced search over years worth of execution records, over multiple versions of continuously upgraded StackStorm.

  • At-scale refinements: Ensure event handling reliability, and event storm resilience. Complete support for multi-node deployment of sensor containers and rules engines for resilience and throughput.

  • DB/Filesystem Consistency: Provide better tooling for managing consistency between database and filesystem consistency for rules, actions, sensors, etc.

  • Configurable Sensors: Run multiple instances of the same sensor, with different configurations.

  • Pack Dependency: Better automatic handling of pack dependencies.

  • Pluggable Configuration: Support multiple configuration backends for better security.

  • RBACv2:

    • Filters: Tag and property based filters, more refined and convenient access control.

    • Permissions: Permissions on key value objects, arbitrary triggers, support for a default role.
