Claudetop – htop for Claude Code sessions (see your AI spend in real-time)

Claudetop is the first real-time usage monitor for Claude Code sessions, letting developers see exactly how much they're spending on AI tokens per command. It displays per-session and cumulative costs, token counts, and API call frequency in a terminal dashboard inspired by htop. In a 30-minute coding session, users can save over $2.50 compared to running commands blind — the tool surfaces expensive queries before they hit the bill. Unlike the typical 'guess-and-check' workflow, Claudetop provides immediate, per-command cost breakdowns, helping users optimize prompts and cut wasteful API usage. For heavy users running multiple parallel sessions, this can reduce monthly costs by up to 40% compared to not using any tracker.
