Leantime vs OpenProject: at a glance
What is Leantime?
Leantime is stabilizing its big 3.9 rewrite while extending cross-project planning and a mobile API
Leantime is deep in a modernization cycle. The 3.9.0 release rebuilt the app around a native, fail-closed permission engine, a JSON-RPC API, and a consolidated Blueprints domain; the releases since then mostly stabilize that foundation. Recent point releases fix regressions (repeated Bearer/PAT auth fixes) while adding cross-project program views and a mobile app backend.
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.

Leantime is stabilizing its big 3.9 rewrite while extending cross-project planning and a mobile API
◆ Current state
Leantime is deep in a modernization cycle. The 3.9.0 release rebuilt the app around a native, fail-closed permission engine, a JSON-RPC API, and a consolidated Blueprints domain; the releases since then mostly stabilize that foundation. Recent point releases fix regressions (repeated Bearer/PAT auth fixes) while adding cross-project program views and a mobile app backend.
◆ Where it's heading
The work is consolidation over expansion: hardening the new auth/permission and API layers, closing security IDORs domain by domain, and building the surface a mobile app and program-level planning need. The steady stream of small patch releases reflects shaking out regressions from the 3.9.0 refactor rather than opening new product directions.
◆ Prediction
Expect continued point releases fixing regressions from the permission-engine and JSON-RPC migration, plus buildout of the Leantime Mobile app now that its Bearer-authenticated backend API is landing.
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.
