Start with the status audit, because it settles most of the decision. Kanboard 1.2.53 arrived in July 2026 and needs PHP 8.1 or newer. Phproject reached 1.8.4 in March 2026 and is the work of one developer, Alan Hardman, a fact to weigh rather than a criticism. Feng Office Community Edition published 3.11.13.11 in December 2025. dotProject last shipped a packaged release, 2.2.0, in March 2020, and the newest commit in its repository is from November 2024, merging a pull request titled "First attempt to get PHP 8.0 support". PHP 8.0 itself stopped receiving security fixes in November 2023. We will install dotProject if you ask, but not with our recommendation.
None of these are heavy. Kanboard on our entry web hosting plan handles a working team, and the thing that grows is attachments rather than the database. Two details catch people out. Kanboard is documented as incompatible with Apache mod_security, so a blunt firewall rule set breaks it in ways that look like random failures. And SQLite, which Kanboard supports and which tempts people because it needs no setup, is documented for a single user or small teams with minimal concurrency. Choose MySQL at install time and skip that migration later.
Skip the category if you need iOS and Android apps, Slack or Teams integration, single sign-on, or reporting a finance director will sign off. Buy Asana or Jira for that.
