Tududi is a self-hosted planner that turns a pile of tasks into a plan for the day, keeping projects, notes, goals, and habits on a server you control. One Add box files an Inbox item, Task, Note, or Project and understands natural-language dates, recurrence, tags, projects, and people, so "every first monday #home" becomes a recurring task without opening a form. The Today page switches between planning mode, with a timeline or list beside your calendar and optional AI help to sketch the day, and doing mode, with a Next card and a hint when a free slot fits a small task. Tasks have subtasks and live in projects and areas, projects link to season or year goals, and saved views, project templates, and optional Eisenhower and Kanban boards organize the work. Habits support build or quit goals with streaks, a strength score, and a history grid, while notes offer linked pages, backlinks, and mermaid diagrams. Households and teams share projects with read-only or read-write access, assign tasks to people, and follow an Everyone board; members without email sign in through one-time links. Telegram captures tasks and can send daily summaries, CalDAV syncs with reminder apps, OIDC handles single sign-on, and an MCP server lets Claude or Cursor manage tasks. AI stays off until you enable it and add a provider; local models work too.

A personal to-do list that scales to team project management: Vikunja is an open-source task manager that grows with the work. Every project can be viewed four ways - classic list, drag-and-drop Kanban board, Gantt chart for timeline planning, and a spreadsheet-style table - so a project manager watches the Gantt while developers work the board, on the same data. Tasks carry the full attribute set: labels, priorities, due dates and reminders, recurring schedules, subtasks and task relations, file attachments, assignees, and comments, and Quick Add Magic parses natural-language input like dates and labels typed inline. Projects share with team members or via links, and saved filters slice tasks across projects. Built-in CalDAV support (VTODO) syncs tasks bidirectionally with clients like Thunderbird, DAVx5, and iOS Reminders, and one-click importers migrate from Todoist, Trello, and Microsoft To-Do. Nothing is metered - unlimited projects, tasks, filters, and attachments. A single Go binary with a Vue frontend runs against SQLite, MySQL, or PostgreSQL, exposes a full REST API, and works as an installable PWA on mobile. AGPLv3-licensed.

Grocy is a household management system, bringing ERP-grade inventory tracking to kitchens, pantries, and homes worldwide. The stock management system tracks products with expiration dates, best-before dates, and opened tracking, while barcode scanning via USB readers or device cameras with Open Food Facts product lookup enables rapid item entry. Minimum stock amounts trigger automatic shopping list entries so frequently used products never run out, and multiple shopping lists can be maintained and shared across household members. Recipe management links ingredients directly to stock inventory, showing at-a-glance fulfillment status and a Due Score that highlights recipes best suited for consuming items approaching expiration. The meal planner organizes daily meals across customizable time periods and adds all missing ingredients to shopping lists with one click. Chore tracking schedules recurring household tasks with assignment to specific members, due date tracking, and completion history logging. Battery management monitors charge cycles for household devices with configurable reminder intervals. Custom fields and userfields extend any entity with additional data, while feature flags disable unused modules to simplify the interface. The RESTful API with integrated Swagger UI at the /api endpoint exposes every operation the web frontend uses, enabling third-party integrations with home automation systems.

Replace a dozen household subscriptions with one app that keeps your family's tasks, calendars, meals, budget, and shopping in a single private place you control. Nineteen modules cover the daily rhythms of a household: assign chores with deadlines and priorities, plan the week's dinners and push the ingredients to a shared shopping list in one tap, track income and expenses by category with automatic subscription renewal warnings, and log health activities from vitals to medications. Two-way sync connects to Google Calendar via OAuth, iCloud and Nextcloud via CalDAV, and Outlook via Microsoft Graph, so every family member's phone shows the same schedule without switching apps. CardDAV keeps contacts in sync with external address books. The budget module handles accounts, loans, split expenses, and per-category planning with savings goals and month-over-month comparisons. Documents attach to tasks, receipts link to transactions, and a checked-off grocery item books itself back into the pantry inventory with its quantity. A Kanban board, recurring task schedules, and a rewards ledger that pays out points for completed chores keep kids and adults accountable. Wall mode turns a kitchen tablet into a glanceable family dashboard, and the Immich screensaver shows your own photos when the screen goes idle. API tokens and a built-in MCP endpoint let AI agents and third-party tools interact with every module programmatically.

Super Productivity eliminates the context switching between issue trackers, calendars, and timer apps that fragments developer focus, pulling tasks from Jira, GitHub, GitLab, Gitea, OpenProject, Linear, ClickUp, Trello, and Azure DevOps into one local-first interface. With 21,000+ stars and availability across web, desktop, Android, and iOS, it syncs issue status, subtasks, and time logs bidirectionally so sprint planning and worklog submission happen without leaving the app. CalDAV integration pulls calendar events into your task timeline for visual timeboxing. Built-in Pomodoro and Flowmodoro timers enforce focused intervals with configurable break schedules. Data stays under your control in browser IndexedDB by default, with optional AES-encrypted sync via WebDAV, Nextcloud, Dropbox, or the SuperSync server ensuring no task data touches infrastructure you do not own. The extensible plugin system supports JavaScript-based custom panels, automations, and MCP plugins for AI workflows. A REST API on port 3876 enables external script integration for desktop automation. Time tracking generates exportable timesheets compatible with corporate reporting systems. The Docker container serves the Angular PWA through Nginx on port 80, consuming roughly 50 MB of RAM.

No external database cluster to babysit, no proprietary cloud lock-in, and no bloated workspace hierarchy: Jotty stores every note, checklist, and Kanban board as plain Markdown and JSON files inside a single folder on your server. Need a quick grocery list with nested categories, progress bars, and drag-and-drop reordering? Spin one up in seconds, or flip any list into a multi-column Kanban project board with custom statuses, due-date calendar views, and a built-in time tracker. Write technical documentation in a TipTap-powered WYSIWYG and Markdown editor featuring syntax-highlighted code blocks, GitHub-flavored callouts, embedded Draw.io and Excalidraw diagrams, and OpenPGP client-side encryption for sensitive records. Connect ideas across your workspace using Obsidian-compatible wikilinks, inline mention suggestions, backlinks, and an interactive 2D and 3D knowledge graph that maps relationships between tasks and notes. Share individual notes or live Kanban boards publicly via customizable read-only links, or start the optional Model Context Protocol (MCP) companion container so AI assistants like Claude and Cursor can query your notes and check off items through your scoped REST API key.

Manage My Damn Life is a personal productivity platform and CalDAV task manager that gives individuals and teams a full-featured web workspace for coordinating todos, calendar agendas, and project schedules without relying on proprietary productivity software. Users can connect multiple CalDAV server backends including Nextcloud, Radicale, and Baikal to synchronize tasks, events, and subtasks across their self-hosted infrastructure. The interface offers multiple interactive perspectives, letting planners switch between nested task checklists, full monthly calendar grids, and dynamic Gantt chart roadmaps with customizable timeline scales. Keyboard-driven operators can rapidly log action items via intuitive Quick Add syntax that parses due dates, priority tiers, and category labels from inline text triggers. A versatile filter manager allows users to save custom query views matching due dates, completion statuses, parent task hierarchies, and color-coded labels. Team members can establish reusable task templates for recurring administrative workflows, assign multi-level checklist items, and manage individual calendar visibility across shared workspaces. System administrators can configure user authentication through native accounts or integrate enterprise Single Sign-On using OpenID Connect providers like Keycloak, Authentik, and Google. Client-side state caching accelerates navigation while background sync preserves CalDAV compliance.

No targets, no gamification spiral, no motivational nagging: Beaver Habit Tracker is a self-hosted habit tracker deliberately built without "Goals". The core loop is honest: add habits, check them off each day, watch streaks accumulate on a calendar view. Its design follows behavioral-science basics - make it obvious (visual streak cues), make it attractive (progress is the motivator), make it satisfying (tracking becomes its own reward). Beyond the daily checklist it supports per-day notes intelligently grouped per habit, periodic habits, habit categories and tags, drag-to-reorder (manual or automatic), dark mode, and detailed streak and frequency views. Data lives where you choose: a single SQLite database or flat JSON files on a mounted volume, with JSON export and import for full portability. A REST API opens automation - community integrations already cover Stream Deck buttons, Home Assistant triggers, and CalDAV. The Python app ships as one Docker container with no external dependencies; environment variables tune everything from first day of week and index-page columns to iOS standalone PWA mode, and single-user setups can bypass the login entirely with TRUSTED_LOCAL_EMAIL. BSD-3-Clause licensed with no commercial restrictions - a well-executed single-purpose tool whose mobile PWA works anywhere a browser does.

"Less is more" is Kanboard's stated philosophy, and the free, MIT-licensed PHP application lives it: drag tasks between customizable columns, enforce work-in-progress limits per column, and slice boards horizontally with swimlanes for releases, teams, or priorities. Tasks carry what matters - colors, categories, subtasks with time estimates, Markdown descriptions, comments, attachments, internal links, and due dates - and move or duplicate across projects in one click. A concise query language filters any board dynamically (assignee, category, due date, description), and saved filters become custom views. The automatic-actions engine kills repetitive triage: on events like column moves or task creation, Kanboard reassigns, recolors, recategorizes, or closes tasks by rule. Around the board sit a calendar, per-project analytics (cumulative flow, lead and cycle time), Gantt view, and time tracking. Authentication spans LDAP/Active Directory, Google, GitHub, GitLab, and reverse-proxy headers; a JSON-RPC API, webhooks for creating tasks from external systems, and a CLI cover integration. A large community plugin catalog adds what core deliberately omits. With no external dependencies, it runs happily on anything from a Raspberry Pi up - translated into 30+ languages.

From the Mattermost team comes Focalboard, an open-source, MIT-licensed project board tool - a self-hosted alternative to Trello, Asana, and Notion databases, written in Go with a React frontend. Every board renders the same card data four ways: Kanban with drag-and-drop columns, a spreadsheet-style table, an image-forward gallery, and a calendar. Cards carry unlimited custom properties - dates, dropdowns, checkboxes, people, URLs - and boards can be grouped, filtered, and sorted by any property combination, with unlimited saved filtered views for quick access. Built-in templates cover the common workflows (meeting agendas, content calendars, project tasks, roadmaps, sprint planning), or you can build fully custom boards from scratch. Collaboration is real: card comments with @mentions, per-board permissions for teams or individuals, file attachments stored on your own infrastructure, and archiving with backup snapshots. Migration tooling imports existing boards from Trello (JSON export), Asana, and Notion, so switching does not mean starting over. It ships in 20+ languages and runs as a lightweight multi-user personal server. Worth knowing before deploying: Mattermost has shifted primary development to the integrated Mattermost Boards plugin, so the standalone edition is community-maintained - stable and functional, but evolving slowly. For teams wanting a free, private Trello without per-user fees, it remains a solid pick.

The deep end of self-hosted recipe management: Tandoor Recipes is a Django/Vue application that replaces Paprika, AnyList, and ad-choked recipe sites with a database you control. Import is where most people start: paste any URL and Tandoor scrapes schema.org markup for ingredients, instructions, images, times, and nutrition; bulk-paste URLs for batch import; or migrate wholesale from Mealie, Paprika, Nextcloud Cookbook, Pepperplate, and other managers with built-in importers. The structured recipe editor tracks ingredients individually, which is what powers everything downstream: full-text search with trigram similarity, a "what can I make with what's in the fridge" ingredient search, automatic nutrition via OpenFoodFacts, and shopping lists that merge duplicate ingredients across recipes, convert units, scale by servings, and sort by your supermarket's actual aisle layout. The weekly meal planner is drag-and-drop, feeds shopping lists automatically, exports to your calendar, and shows a nutritional summary for the week. Multi-user support comes with a granular permission system - shared household cookbooks, private recipes, even secret ones - and shopping lists sync in real time so two people can shop simultaneously. A full REST API integrates with Home Assistant and Grocy. For households serious about cooking, Tandoor's depth is unmatched.
