Mindwtr is a free, open-source, local-first task and idea management app built around the Getting Things Done (GTD) workflow. It captures tasks, ideas, and worries in an Inbox through desktop hotkeys, mobile widgets, share sheets, or voice input; guides users through sorting items into scheduled tasks, next actions, waiting-for items, projects, and Someday/Maybe; and provides Focus and guided weekly-review views. It supports projects with sections, areas, and manual task ordering, and is available for desktop, mobile, and web use. Data is stored on the device by default, with optional synchronization through iCloud, Dropbox, shared folders, a user-owned server, or WebDAV; the project states that it requires no account or subscription.

Super Productivity is an open-source task and day-planning application with sub-tasks, projects, tags, timeboxing, time tracking, timers, work summaries, and personal productivity metrics. It can import assigned tasks from Jira, Trello, GitHub, GitLab, Gitea, OpenProject, Linear, ClickUp, Azure DevOps, and other sources while keeping planning details local. The application supports task notes, file attachments, project bookmarks, break reminders, anti-procrastination prompts, a Pomodoro timer, basic CalDAV integration, and exports for work logs and time sheets. Data can be synchronized across devices through SuperSync, Dropbox, or WebDAV; SuperSync is described as an end-to-end encrypted service that can also be self-hosted. It is available as a web application and downloadable applications, requires no account or registration, and states that it does not collect user data. The project is free and open source, with platform support including Android, iOS, Linux, macOS, and Windows.

DeepTutor is an open-source, self-hostable AI tutoring platform developed by HKUDS for lifelong personalized tutoring. It provides a web application and command-line interface for interactive learning, problem solving, quiz generation, deep research, visualization, and mastery practice, with persistent memory and learning state shared across knowledge bases, books, notebooks, tutor personas, and other activities. The platform supports multi-agent problem solving, retrieval-augmented learning with source-traced and page-level citations, math animations, interactive visualizations, and tutor bots built from personal study materials. Its knowledge sources include personal documents, EPUBs and books with annotations, GitHub repositories, web search, and connected libraries; documented retrieval and ingestion options include GraphRAG, PageIndex, LightRAG, linked knowledge bases, Obsidian, and configurable parsing and vector backends. DeepTutor also includes courses, research workflows, an ecosystem of MCP services and tool or capability plugins, and integrations with connected coding agents and other partners. It can run locally or through Docker.

mirador is an open-source terminal dashboard built with Rust and ratatui for keeping in a terminal tab and glancing at throughout the day. It provides configurable panels for world clocks, a calendar and agenda, weather, an editable task list, notes, a market watchlist, a calculator, RSS news feeds, and live CPU and network charts; panels can be enabled, rearranged, focused, and edited through keyboard controls. Tasks, notes, and the watchlist are stored as hand-editable TOML files rather than in a database or sync service. The dashboard uses keyless public endpoints for weather and market data and configurable RSS feeds for news; the project states that it requires no account, API key, or telemetry and does not contact external services unless requested.

SnagTime is a free, self-hostable scheduling application that provides account and workspace management, event types, availability rules, public booking links, time-zone handling, custom booking questions, rescheduling, cancellation, and recovery links. It checks Google Calendar free/busy status and can create calendar events, sends organizer and invitee messages through SMTP, and supports Stripe Checkout in test mode with webhook confirmation and refund handling. The local demo uses SQLite, a local calendar adapter, a local email inbox, and stub payments; production deployments use a PostgreSQL architecture with a web service, background worker, persistent database, and webhook endpoints. The application is a Next.js project with Prisma schemas and migrations, distributed under the MIT License. It is intended for self-hosting rather than as a managed service; external Google Calendar, SMTP, Stripe, hosting, domain, and database services must be supplied and configured by the operator.
