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.

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. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.

Recurring household chores and shared team checklists stay on schedule when Donetick coordinates assignments, reminders, and completion tracking from one self-hosted hub. Type a phrase like "change water filter every 6 months" and the natural-language parser extracts the due date and cadence automatically. Adaptive scheduling even adjusts future intervals from your actual completion history. Rotation rules distribute tasks fairly across family members or roommates via round-robin, random, or least-completed logic. Nested subtasks reset themselves each cycle. Finished chores earn points in the built-in gamification engine that members redeem in an admin-approved reward store. Stateful "Things" track numerical, boolean, or text metrics to trigger tasks automatically when values change. Tap physical NFC tags to check off chores on the spot, or mount a dedicated kiosk dashboard on a wall tablet for one-tap account switching. Real-time updates sync across devices alongside iCal calendar feeds, Home Assistant cards, OIDC single sign-on, and Pushover or Telegram notifications. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3.0 licensed.

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. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.

Instead of locking your daily schedule inside proprietary cloud calendars, dayGLANCE offers a privacy-first visual time-blocking planner that syncs directly with your own WebDAV server, Nextcloud instance, or Obsidian vault. Drag tasks from a prioritized Smart Inbox onto an interactive 24-hour timeline, resize blocks as priorities shift, and carve out recurring energy-tagged Frames for deep work or administrative batches. The live Glance panel highlights your current commitment, remaining free time, and daily routines, then transitions into GLANCEahead each evening to preview tomorrow's start time, deadlines, and total committed hours. Switch between multi-day, single-day, weekly, and monthly layouts, or launch the fullscreen Day Dial to view your schedule, solar daylight arc, and watch-style progress complications on a secondary wall display. Long-term work stays organized inside a Goals and Projects hierarchy with duration-weighted progress bars, visual roadmaps, and dedicated hyperGLANCE focus workspaces that pair a Pomodoro timer with project notes and subtasks. Bidirectional Obsidian synchronization reads and writes markdown daily notes and wikilinked tasks directly, while optional bring-your-own-key AI assistants and encrypted backups keep your productivity workflow completely under your control. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.

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. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. GPL v3 licensed.

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.

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. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3.0 licensed.

Unlike a calendar alert that rings on one phone, a MIND reminder reaches any of 100+ services, including email, Pushbullet, BlueSky, Cisco Webex Teams, and SMS gateways, from a self-hosted reminder app that you control. Normal reminders fire with second precision once or repeat every few days, once a year, on chosen weekdays, or on a custom cron schedule, while static reminders wait for a button press, so a single tap can tell the family that you are running late. Templates store colour, title, services, and text for fast creation, and the colour-coded library can be searched and sorted, with each reminder enabled, disabled, or tested on demand. Time zone changes, including daylight saving shifts, are accounted for, and sends that fail on a connection error are retried every two minutes until they succeed. Several users can share one instance: the admin panel handles accounts and registration, login lifetime, reverse-proxy URL prefix, debug logs, and scheduled database backups that can be exported and imported, and sign-in supports two-factor authentication. A documented REST API covers reminders, templates, notification services, and static triggers, and the web interface adapts to phone screens. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. GPL-3.0 licensed.

A Day One alternative that keeps your most personal writing on your own server: Journiv is journaling purpose-built for self-hosters. The FastAPI backend runs on SQLite by default with optional PostgreSQL, Redis, and Celery for background work, behind a clean, minimal web UI. Unlike general note-taking apps, it ships the features journaling actually needs: customizable moods and mood groups, activity tracking, goals with automated progress from logged activities, and daily writing prompts filterable by category and difficulty so a blank page never stalls you. Quick Log captures a moment in seconds and expands into a full entry later; "On This Day" resurfaces entries from past weeks, months, and years. Multiple journals separate work, gratitude, and personal writing, with tags and full-text search across everything, plus media uploads with automatic thumbnails and an Immich integration for linking photo-library memories. Analytics chart mood trends and writing patterns over time. Data portability is taken seriously: native import of Day One exports, JSON/Markdown/HTML export, and a standalone HTML viewer that opens your archive in any browser with no server running. OIDC single sign-on works with Authentik or Keycloak, and multi-arch images cover amd64 and arm64.

Standard Notes keeps your notes, files, and tags encrypted on your device before anything touches the network, meaning the server stores only ciphertext it cannot read. Cross-platform sync across desktop, mobile, and web delivers fast, conflict-free updates on unlimited devices with the same zero-knowledge guarantee that only your password can decrypt your content. The V2 server architecture condenses everything into four Docker containers consuming roughly 570MB RAM total (down from 13 containers and 1.7GB in the legacy setup), with startup under one minute. Revision history automatically preserves every version of every note, so recovering deleted text or reverting to a previous state never depends on manual backups. A nested tag system organizes thousands of notes with hierarchical categorization that goes well beyond flat folder structures, while search operates entirely on client-side decrypted content. File attachments of any type encrypt and sync alongside notes with identical end-to-end protection. Multiple editor options span plain text, Markdown with preview, and rich formatting to fit different writing workflows. Two-factor authentication via TOTP with email backup codes adds a second barrier beyond your password. An optional separate container serves the web frontend, providing browser access to your encrypted vault without depending on standardnotes.com infrastructure. With 5,500+ GitHub stars and active development, the project continues expanding editor plugins and sync improvements.

Open the page, write a Markdown note, move on - Memos is a lightweight, self-hosted service built for quick capture. Instead of folders, notebooks, and titles, it presents a timeline: open the page, write a Markdown note, and move on. Notes support headings, code blocks with syntax highlighting, task lists, tables, and file attachments, with tags auto-extracted from #hashtags in the text. Each memo carries a visibility level, private, protected (logged-in users), or public, so one instance works as a personal log, a small team wiki, or a lightweight microblog. The backend is a single Go binary with a React frontend, around 50 MB of memory at runtime and a ~20 MB Docker image, so it fits comfortably on the smallest instance size with near-zero maintenance. SQLite is the default store, with MySQL and PostgreSQL supported for multi-user deployments needing more concurrency, and full REST and gRPC APIs - Connect RPC for browsers, gRPC-Gateway for external tools - make capture scriptable from CLIs, bots, and automation platforms. Fast full-text search spans all memos, pinned notes keep references handy, and a masonry view suits visual browsing. MIT-licensed with zero telemetry; content is stored as plain Markdown in a database you control, so notes remain readable, exportable, and free of proprietary formats.

Notes on Windows, macOS, Linux, Android, iOS, and the terminal, synced through your own server: Joplin pairs its open-source clients with Joplin Server, the official self-hosted backend that replaces Dropbox, OneDrive, or Nextcloud as the synchronization target. Notes are Markdown with inline attachments (images, PDFs, audio), organized into hierarchical notebooks and sub-notebooks with cross-cutting tags, alongside to-do lists with reminders and alarms. End-to-end encryption is the headline feature: enabled in the clients, it encrypts sync payloads on-device before upload, so the server stores blobs it cannot read - genuine protection even if the host is compromised. The desktop app offers both Rich Text and Markdown editors, extended by a plugin ecosystem, custom themes, and an Extension API for writing your own scripts; a Web Clipper for Chrome and Firefox captures full pages or screenshots straight into notebooks. Joplin Server ships as a Docker image with SQLite for evaluation and PostgreSQL for production, offers a filesystem storage driver for large content, and includes multi-user support and note sharing - all free under AGPL-3.0 when self-hosted. Notes stay in an open format, so the exit path always exists.

A web interface for a folder of Markdown files - Flatnotes is exactly that, and the discipline of that design is why people love it. Every note is a plain .md file in a single flat directory: no database, no proprietary format, no hierarchy to maintain, no export step if you ever leave. Edit notes in the browser or open the same files in VS Code or Obsidian, sync them with Syncthing or rsync while the app is running - the Whoosh-powered search index synchronizes incrementally, so external edits just show up. The interface is a clean Vue.js app with both WYSIWYG and raw Markdown editing modes (TOAST UI Editor), instant full-text search behind the "/" shortcut with partial-match support, wikilinks for cross-note references, and automatic tag extraction from #hashtags in note bodies. Light and dark themes and a mobile-responsive layout make it pleasant everywhere. Authentication is flexible for a personal tool: none, read-only, username/password, or TOTP two-factor. A documented REST API covers create/read/update/delete for automation. The operational story is the quiet selling point - the only state is the notes folder and a rebuildable index, so backup is copying a directory. For a personal notepad that respects your data, Flatnotes nails minimal.

Backed by over 45,000 GitHub stars and described as the tool that replaces Notion, Evernote, and Anki in a single Docker container, SiYuan is the privacy-first knowledge management system where every paragraph, heading, and list item is a uniquely addressable content block. The block-level architecture enables bidirectional links, transclusion embeds, and SQL query blocks that dynamically aggregate content across your entire workspace, while the knowledge graph visualization maps relationship networks between documents and blocks. Built-in databases support table views with relation and rollup columns, filter composition, sorting, and template-based calculations for structured data management alongside freeform notes. The FSRS spaced repetition engine turns any content block into a flashcard with scientifically calibrated review scheduling, eliminating the need for separate memorization tools. AI integration connects to OpenAI-compatible APIs for writing assistance, translation, summarization, and Q&A chat, with semantic search using embeddings and reranking for intelligent content retrieval. The Bazaar community marketplace delivers plugins, themes, templates, and widgets through a managed extension system with TypeScript plugin APIs. End-to-end encrypted synchronization works across S3-compatible storage, WebDAV servers, or SiYuan's own cloud service, while Tesseract OCR extracts searchable text from images and the web clipper captures pages from Chrome, Edge, and Firefox. Export targets include Markdown with assets, PDF, Word, and HTML. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console.
