Vikunja vs Celoxis
A side-by-side editorial comparison of Vikunja and Celoxis — release velocity, themes, recent moves, and the top alternatives to consider.
Vikunja vs Celoxis: 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 Celoxis?
Celoxis's feed is wall-to-wall SEO comparison content; no product releases
Every recent entry is search-optimized comparison or best-practices content: best business management software, Airtable alternatives, enterprise PM guides, all positioning Celoxis against competitors. None describe a product change. This is a marketing feed, not a changelog.

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.

Celoxis's feed is wall-to-wall SEO comparison content; no product releases
◆ Current state
Every recent entry is search-optimized comparison or best-practices content: best business management software, Airtable alternatives, enterprise PM guides, all positioning Celoxis against competitors. None describe a product change. This is a marketing feed, not a changelog.
◆ Where it's heading
The output reflects a demand-generation strategy aimed at enterprise PMO buyers, not product development. Where the product is actually heading isn't observable from these posts.
◆ Prediction
The blog will keep publishing competitor-comparison and PMO best-practice content. Tracking real Celoxis releases would require a different source.
