StackStorm is still under active development. We welcome community feedback, and encourage contributions. Here’s what we see as our top priorities:

  • Multi-node deployments: Provide platform support for content deployment to multiple worker nodes, with better integration with git/GitHub. Simplify development and deployment of “automation as code” at scale.
  • Multi target configurations for integration packs: For a given integration pack, define and manage multiple targets. This should allow the user to choose which one of a set of configurations to use for a given action.
  • 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.
  • Security hardening: Complete security audit and address issues discovered so far.
  • First class Windows support: switch to pywinrm for better license. Remote PowerShell via Powershell.REST.API. Windows-native ActionRunners.
  • Projects and Uber-flow: Introduce projects to group and manage rules and workflows. Handle versions and dependencies. “Productize” flow-rule-flow-rule chain pattern, aka “uber-flow”. Manage large number of automations across users and teams, on a single StackStorm deployment at enterprise scale.
  • Action Output Structure Definition: Enable optional definition of action payload, so that it can be inspected and used when passing data between actions in workflows.
  • 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 to be assigned to new users.
    • WebUI: UI for RBAC configuration.
    • ChatOps: Allow users to authenticate with StackStorm via bot on chat. Check permissions of the user who triggered an action/ran a command. Introduce a special set of permission types for ChatOps.
  • More integration packs: push more content to the community to help work with most common and widely used tools. Tell us if there is a tool you love and think we should integrate with, or better yet write a pack!
