Show HN: BurnRate – Track what you spend on AI coding tools

I was paying $100/mo for Claude Code Pro and had no idea where it was going. I'd hit the 5-hour rate limit constantly, but couldn't tell which sessions were burning through my allocation or whether Opus was worth the premium over Sonnet for my workflows. So I built a tool to find out. BurnRate is a local CLI that parses your AI coding tool session data and gives you a full cost analytics dashboard. It tracks Claude Code, Cursor IDE, and OpenAI Codex in one place. Everything runs 100% on your machine. Your session data, token counts, costs, prompts - none of it leaves your computer.
