Costwell: AI Cost & Burn Rate

来自 App Store 来源

An unofficial Mac companion for Claude Code. Not affiliated with, endorsed by, or created in partnership with Anthropic. Costwell diagnoses cache misses, attributes dollars to root cause, and prescribes fixes — none of which the standard ccusage tool does. Built for engineers on Pro, Max 5, and Max 20 plans that actually want to lower their bill, not just stare at a number. WHAT IT DOES • Cache Health — quantifies the dollars you waste on cache misses, with a per-reason breakdown built on Anthropic's undocumented cache_miss_reason field • Cost Leaks — ranks the most expensive recurring patterns: tools_changed thrash, oversized prompts, redundant turns • Insights — eight rule-based recommendations with concrete savings, snooze-aware, deterministic • What-If Simulator — repriced any session against any model (Opus → Sonnet) with tokenizer-correct math • Search & Replay — full-text search across 30 days of your conversation history, jump from a leak straight to the source • Code Library — auto-extracted code blocks from your past sessions WHO IT'S FOR Engineers running Claude Code daily. Power users on Pro, Max 5, and Max 20 plans. Teams that want to know where their AI bill actually goes. PRIVACY 100% local. Reads only ~/.claude/projects JSONL files that you grant access to. Nothing leaves your Mac. No analytics, no telemetry, no accounts, no SDKs. PRICING $29 one-time. No subscription. No trial. Pay once, own forever, including all v1. x updates. Unofficial third-party tool. Not affiliated with Anthropic.https://claudepulse.net/support
