A side-by-side editorial comparison of Vikunja and ZenTao — release velocity, themes, recent moves, and the top alternatives to consider.
Vikunja vs ZenTao: at a glance
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 ZenTao?
ZenTao posts a 22.0 beta with no notes in the feed.
The only tracked ZenTao entry is the 22.0 beta tag from October 21. It links to a changelog file in the repository and contains no description of what changed.

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.
