FlyTOmeLight/claudegrain

claudegrain is a macOS menu‑bar app for tracking Claude Code usage and cost attribution with per-repo, per-tool and per‑MCP granularity (plus cache‑hit attribution). It’s aimed at developers who use Anthropic Claude/Claude Code and need precise, local usage accounting and budgeting. Key features: - Per-repo / per-tool / per‑MCP dollar attribution and per‑repo budget alerts - Session and weekly limits, cache‑hit %, 7‑day spend chart, time‑of‑day heatmap, cycle‑aware forecast - Native Swift/SwiftUI app for Sonoma (macOS 14+) with both Apple Silicon and Intel support Data sources (3-tier fallback): 1) OAuth: reads Claude token from Keychain and calls api.anthropic.com 2) JSONL: parses ~/.claude/projects/**/*.jsonl for detailed attribution 3) CLI: shells out to claude /usage as final fallback Install via Homebrew cask or DMG; builds from source available. Privacy: credentials stay local, no telemetry. MIT licensed.
