Both are popular terminal coding agents. Here is how Kaku and Orca stack up on price, strengths and weaknesses, and which one we would pick.

Kaku

7.5 /10

Pricing: Free

Pros

Popular and active: ~6k GitHub stars, 1,660+ commits, MIT licensed
Ships with sensible zero-config defaults, fonts, themes and shell integration tuned for running AI coding CLIs
Built-in glue for a real workflow: pane/tab management plus Lazygit and Yazi integration alongside AI chat/command-suggestion shortcuts
