    TaskExplorer

    TaskExplorer

    Powerful system task manager

    TaskExplorer is a powerful system task-manager / process-inspector tool designed for Windows that goes well beyond the capabilities of the built-in Task Manager. It provides real-time insights into running processes, threads, open handles, network sockets, memory usage, modules loaded, and more โ€” all in a unified, fast, and efficient GUI. Rather than scattering information across tabs or dialogs, TaskExplorer displays detailed data in a panel layout: when you select a process, the lower panel updates dynamically to show relevant info (threads, handles, sockets, modules, etc.), making deep inspection quick and intuitive. It includes advanced panels: a Thread Panel with stack traces (helpful for diagnosing deadlocks or hangs), a Memory Panel that lets you view or even edit process memory (with search capabilities), a Socket Panel showing open network connections, data rates, pseudo-UDP connections (via ETW), and a Modules Panel listing all loaded DLLs and memory-mapped files.

    Task Coach

    Task Coach

    Free flexible open source todo manager featuring hierarchical tasks

However, users are not forced to use all these features; Task Coach can be as simple or complex as you need it to be. Task Coach is available for Windows, Mac OS X, and GNU/Linux; and there is a companion iOS app.

    Impetus

    A key remapping daemon for linux

    Linux lacks a good key remapping solution. In order to achieve satisfactory results a medley of tools need to be employed (e.g xcape, xmodmap) with the end result often being tethered to a specified environment (X11). keyd attempts to solve this problem by providing a flexible system-wide daemon that remaps keys using kernel-level input primitives (evdev, input).

    orbit

    orbit

    Orbit is an issue and project tracker: create projects, track issues

    Orbit started from a simple frustration: most issue trackers make you configure more than you ship. We wanted one place to plan a project, move issues through a workflow, and see progress add up, without the setup getting in the way of the work. How Orbit came to be A short path from a shared frustration to a tool we actually wanted to use. The problem Every tracker we tried asked us to configure more than we wanted to maintain, before a single issue got created. The first version One workspace: create a project, add issues, and move them through a workflow that made sense. Built for teams Roles, dashboards and notifications, so the whole team could rely on the same source of truth. Open and self-hosted Released as a self-hosted tool, so every team keeps full control of their own data.

    AI Dev Tasks

    AI Dev Tasks

    A simple task management system for managing AI dev agents

    AI Dev Tasks is a Markdown-based task management system for AI-assisted software development. It provides structured prompt files that guide an AI coding assistant through feature planning, PRD creation, task breakdown, and implementation checkpoints. The project is designed to work with AI-powered IDEs and CLI agents such as Amp, Claude Code, Windsurf, and similar tools. Instead of asking an agent to jump directly into code, users can follow a staged process that clarifies requirements before implementation begins. This helps reduce vague tasks, missed edge cases, and uncontrolled agent changes. ai-dev-tasks is most useful for developers who want repeatable AI workflows that turn feature ideas into organized implementation plans.

    Beads Viewer

    Beads Viewer

    Task management system for coding agents

    Beads Viewer is a visualization tool designed to display, inspect, and interact with โ€œbead plots,โ€ graphical representations often used in statistical analysis, time series exploration, or clustering visualizations where data points are represented as beads on strands or axes to emphasize patterns and relationships. The viewer provides an intuitive graphical interface that automatically renders bead plots from structured data inputs, enabling users to observe trends at a glance, highlight clusters, or drill down into individual sequences. It supports dynamic interactions such as zooming, filtering by criteria, selecting subgroups, and exporting views for reports or slides. Because bead plots can encode a significant amount of information in compact visuals, Beads Viewer includes customizable styling options โ€” such as coloring by category, adjusting bead size and spacing, and toggling axis representations โ€” to help tailor visuals to specific analytical needs.
