Show HN: Cicada – Claude Code usage analysis TUI

[rnjn]

I wanted a way to see what my Claude Code sessions actually look like over time, and how to build TUIs. so I built cicada. It's a TUI that reads your local Claude session data and gives you basic analysis, token usage, project analytics, tool breakdowns, streaks, and full chat replay right in the terminal. No API calls, no data leaving your machine.

How to install: brew install base-14/tap/cicada or go install github.com/base-14/cicada@latest then > cicada
