LLM Cost Estimator runs on your own machine — the client starts it, so there is no endpoint to ping. 63 installs a week from npm. Last commit 21 Jun 2026.
Token counting & multi-model LLM cost estimates: GPT-4o, Claude, Gemini, 25+. No API key.
Nothing serious here today
Today is the operative word: we check LLM Cost Estimator every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
