Peras

What makes it different

Peras puts a spending line in your Claude Code and Codex week. Set it with `peras set weekly 85 pause`, and once usage crosses your line, the agent's next tool call is refused — or asks first — before it burns the rest of your plan limit. It watches Claude Pro/Max and ChatGPT plan usage, tells you where the week is headed, and lets you pick which notifications you get.

Built by Kristiyan Ivanov, Peras is free and MIT-licensed — the CLI, SwiftBar menu, and app source are all open. A signed, notarized, ready-made macOS app (macOS 13 or later) costs €4.99 once, updates included. It launched on Product Hunt in October 2026, squarely aimed at developers watching their AI coding bills.
