Task manager built for engineering teams, combining status tracking, priority management, GitHub integration, and AI agents that can close tasks automatically.

Macro Tasks is a task management tool aimed squarely at engineering teams who want their work tracking, communication, and documentation in one place. It combines the basics you'd expect from any task management app with tighter developer-focused features: GitHub integration for syncing work with code, and AI agents that can act on tasks rather than just surface them.
Instead of bouncing between a project tracker, a chat tool, and a docs platform, Macro puts tasks, channels, email, and docs in one app. While Linear has a honed task management system, an engineering team using Macro has less context-switching and a single source for what's being worked on.
Key capabilities include:
Most task management tools stop at surfacing information or generating summaries with an agent. Macro's are positioned to take action, closing or opening tasks when needed rather than waiting for a human to update the board.
It's a focused product for teams who find general-purpose project tools too disconnected from how engineering work actually flows. Macro is also open source under AGPLv3 in case you want to self-host or audit what's running.
Privacy-first task manager combining task lists, Kanban, Pomodoro timers, time tracking, and integrations with GitHub, GitLab, and Jira. No account required, works offline.

Super Productivity is a time and task management app built for people who want to do focused, meaningful work without the overhead of accounts, subscriptions, or cloud lock-in. It runs on Windows, macOS, Linux, Android, iOS, and the web. Your data stays on your device by default.
It goes well beyond a simple to-do list. You can organize work as a flat list, a Kanban board, or an Eisenhower Matrix, then drop into a distraction-free focus mode with a built-in Pomodoro timer and customizable breaks. Time tracking is built in, not bolted on, so you can see where your day actually went without switching to a separate tool like ActivityWatch or SolidTime.
Key capabilities include:
It's a practical fit for developers, freelancers, students, and anyone running a GTD-style system. Compared to tools like Todoist, it requires no account and no paid tier to access core features. Everything works offline. The open-source codebase is actively maintained, with a community that ships meaningful updates regularly.
