Vikunja

Vikunja is a self-hosted task and project manager that occupies the middle ground between Todoist's simplicity and Asana's structure. Written in Go (single binary, no PHP), with a Vue frontend. AGPLv3 source, version 2.3.0 dropped last month, and almost 14,000 commits on the main branch. The project ships at a steady pace.

Self-hosting is straightforward in a way that Mautic and SuiteCRM are not. Pull the Go binary, point it at SQLite or Postgres, run it. No PHP runtime, no Apache config, no extra layers. Multiple views (lists, Kanban, Gantt, calendar), labels, subtasks, recurring tasks, attachments, and webhooks all in the box. Mobile apps and a browser extension round it out.

Solo users who want their data on a Raspberry Pi or VPS: install it tomorrow. Small teams frustrated with Todoist or Trello's pricing at multiple seats: self-host and move on. Teams that need vendor support and 24/7 availability: Vikunja Cloud is the team's hosted offering and is reasonably priced.

The catch: Vikunja is a task manager, not a documents-plus-projects suite like Notion or ClickUp. If you want one tool for tasks AND wiki AND databases AND chat, this isn't it. Pair it with Outline or AppFlowy if you need documentation alongside.
