Peras

Peras is a productivity tool designed for developers and AI practitioners who work extensively with Claude Code and Codex. Its primary function is to prevent these AI agents from overusing resources or exceeding usage limits, which can lead to wasted time and potential costs. By setting a weekly usage cap with a simple command, Peras ensures that once the threshold is reached, the agent's next tool call is automatically refused with a clear explanation. This helps users manage their AI interactions more effectively, avoiding long, unproductive tasks that could consume the entire week. The tool offers flexibility, allowing users to pause and resume their agents at will from the terminal or the menu bar. Its CLI and hooks are freely available under the MIT license, while the native Mac menu bar app is a one-time purchase of €4.99, making it accessible for individual developers and teams alike. Overall, Peras is a smart, unobtrusive solution for maintaining control over AI usage in a busy development environment.
