QuotaPanel is an open-source desktop dashboard (Apache-2.0) that pulls the remaining quota of Claude, ChatGPT/Codex, Cursor and Copilot subscriptions, plus API balances on OpenRouter, DeepSeek, Kimi, MiniMax, Z.ai and more (16 sources), into one window that refreshes every 5 minutes. We tested version 0.2.0: supported sources, installation, adding an account, and how it stores keys and what it sends over the network.
