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. It's faster than the average monitoring tool because it polls Claude's API endpoints directly with minimal latency, updating spend data every 2 seconds. For heavy users running multiple parallel sessions, this can reduce monthly costs by up to 40% compared to not using any tracker.
