Vikunja vs Kanboard
Both are free/open-source alternatives to Trello. Here's how they stack up — verified facts, no spin.
Vikunja
A modern task manager with List, Kanban, Gantt, and Table views in one app.
Vikunja is an open-source task and project manager that goes beyond a pure Kanban board: the same tasks can be viewed as a list, a Kanban board, a Gantt-style timeline, or a table. It ships as a single Go binary plus a Vue.js frontend, supports PostgreSQL/MySQL/SQLite, and includes CalDAV sync so tasks show up in any calendar app. A small set of admin-oriented features (admin panel, audit logs, time tracking) require a paid 'Pro' license key even for self-hosted instances; every core feature — including Kanban, Gantt, and the full API — remains free.
Kanboard
A minimalist, low-overhead Kanban board for teams who want speed over features.
Kanboard is a lightweight, self-hosted PHP Kanban application focused on simplicity: boards, swimlanes, task automation rules, subtasks, and time tracking, extendable through a plugin system. It runs on very modest hardware (a small VPS is plenty) and has no external database service dependency by default (SQLite works out of the box, with MySQL/PostgreSQL supported for larger installs).
Side by side
| Vikunja | Kanboard | |
|---|---|---|
| Sovereignty Score | 89 | 86 |
| Open source | Yes | Yes |
| Self-hostable | Yes | Yes |
| Local-first | Yes | Yes |
| License | AGPL-3.0 | MIT |
| Pricing | Free / self-host for all core features; Pro add-ons (admin panel, audit logs, time tracking) via a paid license from ~$5/user/month; managed Cloud hosting also available | Free / self-host (paid cloud hosting plans available from the maintainer) |
Vikunja edges it on the Sovereignty Score, but the right pick depends on the trade-offs below.
Vikunja
Strengths
- +Four task views (List, Kanban, Gantt, Table) cover more workflows than a Kanban-only tool
- +Natural-language 'Quick Add Magic' parses due dates, priority, labels, and assignee from one line of text
- +CalDAV support integrates tasks into existing calendar apps
- +Very actively developed with a comprehensive test suite and seven built-in importers, including one specifically for Trello
Trade-offs
- −AGPL-3.0 requires anyone who modifies and network-serves Vikunja to release those changes — a real consideration for companies building a hosted product on top of it
- −A handful of genuinely useful admin/audit features sit behind a paid license even when self-hosting, so 'fully free' has a practical asterisk
- −More moving parts (Go backend + Vue frontend + DB) than a single-file tool like Kanboard
- −Newer project than Wekan or OpenProject, so its long-term enterprise track record is shorter
Kanboard
Strengths
- +Very low resource requirements — runs comfortably on a small, cheap VPS
- +Free MIT license with a genuinely simple, fast interface
- +Built-in automation rules and time tracking without needing plugins
- +Plugin ecosystem covers common gaps (Gantt, LDAP, extra integrations)
Trade-offs
- −Visual design is utilitarian — noticeably plainer than Trello or Wekan
- −Smaller contributor base than Wekan or Vikunja, so feature velocity is slower
- −Fewer native views than richer PM tools (no built-in Gantt or table view without a plugin)
- −Collaboration features (comments, mentions, notifications) are narrower than larger suites
