rithm — A To-Do List For Agents

Task-first. Terminal-native.

A workflow designed for how developers actually work.

1

Create task

Add a task with ⌘N. It automatically gets its own terminal session.

2

Work in terminal

Run commands, install deps, edit files. Your shell state persists with the task.

3

Launch agent

Send to Claude, Codex, or Gemini. The agent runs in your task's terminal with full context.

4

Ship

LED turns green on commit. Mark complete. Your terminal history is saved forever.

Built for power users.

Every feature designed for developers who demand more from their tools.
