Trello's board model on your own server: Planka is an open-source Kanban project management tool. Boards organize into projects with lists, cards, labels, due dates, checklists, file attachments, and per-card stopwatch time tracking, all managed through drag-and-drop. Updates propagate over WebSockets, so a teammate moving a card or adding a comment appears instantly for everyone without a refresh - a genuine differentiator among self-hosted boards. Card descriptions use a full Markdown editor, custom fields adapt cards to your workflow, and views switch between Kanban, grid, and list layouts. Authentication supports OpenID Connect single sign-on with Google, Azure AD, Okta, or any OIDC provider - a feature Trello reserves for enterprise plans - and notifications reach 100+ channels including Slack, Discord, Telegram, and SMTP via Apprise. A REST API with 50+ webhook events supports custom integrations, and one-click board import eases migration. Built with React and Node.js on PostgreSQL, translated into 35+ languages, deployed via Docker.

Initiative is a self-hosted, multi-tenant project management platform that organizes projects, tasks, collaborative documents, and schedules into strictly isolated community workspaces without enterprise complexity. Users create distinct communities where data remains strictly partitioned across separate database schemas, allowing agencies, volunteer groups, and gaming guilds to manage multiple client environments from a single deployment. Within each community, initiatives group related projects and documents while interactive drag-and-drop Kanban boards track task progression across custom columns, priorities, and deadlines. Integrated collaborative documents enable team members to co-author notes, project briefs, and meeting minutes in real time with threaded inline discussions and user mentions. Granular role-based permissions let administrators specify exact view and edit privileges down to individual items, while a recoverable trash system prevents accidental deletions from interrupting live operations. Curated marketplace apps supply customizable analytics dashboards, and optional bring-your-own-key artificial intelligence integrations generate task suggestions and summarize lengthy discussion threads. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. GNU AGPLv3 licensed.

"As simple as Trello but as feature-rich as Jira" is how the Leantime team frames its goals-focused project management system for non-project managers - built from the ground up with ADHD, autism, and dyslexia in mind, with behavioral science shaping customizable dashboards, time blocking, low-cognitive-load prioritization, and Kanban, list, table, Gantt, and calendar views so each person works the way their brain does. The PHP application (AGPL, Laravel Blade frontend) connects strategy to execution: tasks with unlimited subtasks and dependencies roll up into milestones on a timeline, sprints and retrospectives handle iteration, and strategy-level blueprint boards - Lean Canvas, SWOT, risk analysis, goal and metric tracking - keep the "why" attached to the work. Knowledge lives alongside: wikis and docs, idea boards, comments on everything, file storage on S3 or local disk, even screen and webcam recording. Time tracking with timesheets supports estimation and client billing. Admin features are serious for an OSS tool: per-project permissions, two-factor auth, LDAP and OIDC single sign-on, Slack, Mattermost, and Discord integrations, a plugin system, and an expanding API that now powers a mobile app. Recent releases added multi-collaborator task assignment and low-vision accessibility improvements. Available in 20+ languages.

Paca is a self-hosted project management platform and Scrumban workspace where autonomous artificial intelligence agents collaborate with human software engineers as first-class Scrum teammates instead of external chat assistants. Engineering teams manage sprints, backlogs, and task lifecycles through a shared real-time board powered by Socket.IO where both humans and agents pick up assignments and post progress updates. A native Model Context Protocol server connects external coding assistants such as Claude Desktop and Claude Code directly into projects, tasks, and sprint data without custom scraping scripts. Distributed agents execute in isolated runtime sandboxes powered by the OpenHands software development kit, co-authoring behavior-driven development Gherkin scenarios with product owners and maintaining living system design documents. Visual event-driven automation builders compose multi-branch trigger, condition, and action pipelines that evaluate task dependency gates and cron schedules. A sandboxed WebAssembly plugin runtime allows developers to write custom backend logic and custom board views using Go or Rust. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. Apache 2.0 licensed.
