What is Vikunja?

Vikunja crossed the v1.0 finish line and pivoted hard into security hardening.

Vikunja shipped two v1.0 release candidates through late 2025 and early 2026, then jumped to a v2 series whose first widely-tagged point release, v2.2.1, is dominated by security work. The latest release patches multiple SSRF and IDOR vulnerabilities, enforces disabled/locked-account semantics across every auth surface (OIDC, API tokens, CalDAV, LDAP), and adds a shared SSRF-safe HTTP client that webhooks and migrations now route through. User-facing feature work has slowed; the visible energy is in plumbing and audit cleanup.

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.

Vikunja vs OpenProject: editorial side-by-side

V0.0

Vikunja crossed the v1.0 finish line and pivoted hard into security hardening.

◆ Current state

Vikunja shipped two v1.0 release candidates through late 2025 and early 2026, then jumped to a v2 series whose first widely-tagged point release, v2.2.1, is dominated by security work. The latest release patches multiple SSRF and IDOR vulnerabilities, enforces disabled/locked-account semantics across every auth surface (OIDC, API tokens, CalDAV, LDAP), and adds a shared SSRF-safe HTTP client that webhooks and migrations now route through. User-facing feature work has slowed; the visible energy is in plumbing and audit cleanup.

◆ Where it's heading

The arc moves from feature-completion (S3 storage, drag-and-drop project moves, hover previews in late 2025) toward platform credibility — closing security gaps a self-hosted task tool needs to clear before serious team adoption. The rapid version-number jump from v1.0.0-rc4 to v2.2.1 in two months suggests v1.0 shipped and the team tagged a v2 line aimed at addressing accumulated authz debt. Expect the next several releases to keep the security-first posture rather than return to a feature push.

◆ Prediction

The next release will likely continue closing remaining authz edges (more IDOR audits, additional credential-stripping in API responses) and bundle a translations and dependency sweep. A user-facing feature push probably waits until the security work plateaus.

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.
