Pricing

App free (Apache 2.0); Halv Cloud $10/month.

Overview

Halv is an open-source desktop app that runs several coding agents side by side (Codex, Claude Code, plus Kimi and GLM), using the subscriptions you already have. Running on your machine, it trims command output and compresses context to use fewer tokens, indexes your code, and shows a running total of estimated savings. A paid add-on, Halv Cloud, picks a model for each task based on difficulty and can switch to another of your accounts when one hits its limit. It runs on macOS, Windows and Linux. Rotating between accounts on different plans may conflict with some providers' terms, so check your plan's rules.
