  • Untick a lesson that didn't happen, and it comes off the bill
  • Copy the email, or save every family's as a Gmail draft
  • Your data stays on your PC, backed up every day

Duck Agents

Your Claude Code sessions, as ducks on a pond.

A small macOS app that shows each session you have running as a duck on a pixel art pond, so you can see at a glance which are working, which have finished and which want you.

An unofficial side project, not made by or affiliated with Anthropic.

A pixel art pond in snow: ducks swimming with ducklings behind them for sessions that are working, and ducks resting on the snowy bank for sessions that have finished, each with its session's name beside it.
The pond in snow, with made-up sessions
