A tiny pixel pet that nibbles your bugs.

Nibbl is a Claude Code mod. Your nibbl hatches after real work, lives above the prompt, and eats the bugs your tests squash. It never blocks, never nags, and costs zero tokens.

It lives above the prompt

One thin band in your terminal. Status on the left, a 32 by 16 pixel scene on the right. Nothing else on your screen changes. Try the buttons under the terminal.

It reacts to real events

Tests pass, errors land, and a few things we won't spoil. If nothing happened, your nibbl just breathes.

Expeditions

While Claude works, your nibbl heads out. When the turn ends it comes back with loot.

Hearts

Click your nibbl for a heart. Up to 5 hearts an hour count toward XP.

There is a secret form. Nobody has found it yet.

It only moves when something real happens

No fake events, no guilt trips. Your nibbl can't die and won't ping you.

Luck gives the start

Every nibbl rolls its own genome when it hatches. Effort gives the form later.

Shiny is rolled separately, so a shiny can come from any tier. Every nibbl has at least one trait rarer than 5%.
