What is Gravity Flow?

Post-3.0, Gravity Flow adds choice-based routing and keeps its extension family current

Gravity Flow is a WordPress workflow-automation plugin fresh off its 3.0 major release, now iterating on the core engine and maintaining a wide extension family (Checklists, Parent-Child Forms, PDF Generator). The headline recent feature is 3.1's Choice Routing step plus a Send to Step bulk action.

What is OpenProject?

OpenProject's MCP Server gains write access — AI agents can now create tasks, add comments, and manage relations.

OpenProject 17.8.0 marks the most significant AI integration milestone in the product's history: the MCP Server can now create and update work packages, add comments, and manage relations — moving from a read-only query layer to a write-capable AI agent interface. The same release adds multiple target versions per work package, sprints and milestones to the project timeline, and relation display in the free Community edition. OpenProject 17.7.0 laid the organizational management foundation: departments, work-related user attributes, and individual work schedules for capacity planning.

Gravity Flow vs OpenProject: editorial side-by-side

G2.5

Post-3.0, Gravity Flow adds choice-based routing and keeps its extension family current

◆ Current state

Gravity Flow is a WordPress workflow-automation plugin fresh off its 3.0 major release, now iterating on the core engine and maintaining a wide extension family (Checklists, Parent-Child Forms, PDF Generator). The headline recent feature is 3.1's Choice Routing step plus a Send to Step bulk action.

◆ Where it's heading

The 3.0 rebuild reset the foundation; 3.1 shows the payoff arriving as concrete workflow primitives — routing by field choice, bulk step moves. Alongside, the extensions are being kept in lockstep with 3.0 (including a breaking PDF Generator 3.0). Direction is deepening workflow-authoring capability on a modernized base.

◆ Prediction

Expect more routing and step-type primitives layered onto the 3.x engine, and continued extension updates aligning each add-on with the new core.

O6.3

OpenProject's MCP Server gains write access — AI agents can now create tasks, add comments, and manage relations.

◆ Current state

OpenProject 17.8.0 marks the most significant AI integration milestone in the product's history: the MCP Server can now create and update work packages, add comments, and manage relations — moving from a read-only query layer to a write-capable AI agent interface. The same release adds multiple target versions per work package, sprints and milestones to the project timeline, and relation display in the free Community edition. OpenProject 17.7.0 laid the organizational management foundation: departments, work-related user attributes, and individual work schedules for capacity planning.

◆ Where it's heading

The two-track development pattern is clear: broader project management capabilities for enterprises (resource management, capacity planning, PM² methodology support) and a rapidly maturing AI interface through the MCP Server. The progression from read-only MCP to write-capable MCP is a qualitative shift — AI assistants become active project participants rather than passive query tools. The XWiki integration in 17.6.0 shows the platform also extending into enterprise knowledge management.

◆ Prediction

The logical next step is workflow automation via the MCP Server — AI agents that can trigger status transitions, query resource availability from the 17.7.0 capacity data, or auto-assign work packages based on department membership. The data model is in place; the automation layer is the missing piece.
