Reduce Claude Code token usage by 60-70% with persistent codebase caching.

Features

Live Dashboard

Visual dashboard showing real-time token savings, cache hit rates, and performance metrics.

Token Savings — Live stats: hits, misses, tokens saved, cost saved
Indexed Files — Browse your indexed project tree
Symbols — Search extracted functions, classes, types

How it works

CodeTree indexes your codebase into a persistent SQLite database. When Claude Code tries to read a file, search for code, or list files — CodeTree intercepts the call and serves cached results instead, saving tokens.

Claude Code Action	Without CodeTree	With CodeTree
Read a file	Full file re-read every time	Served from cache if unchanged
Grep for a symbol	Scans all files	Returns indexed matches instantly
Glob for file structure	Lists entire directory	Returns cached tree

Status Bar

Shows live cache hit rate and cumulative token savings right in your status bar.
