Your coding agent resends files, diffs, instructions, and logs it has already seen. Halv cleans that wasted context locally before each request reaches the model—so you keep the same CLI, login, model, and subscriptions while getting far more work from your plan. It supports Claude Code, Codex, Kimi, and GLM, with split terminals, multi-agent workflows, local sandboxing, a Crux code index, and a receipt showing the usage saved on every answer. Available on macOS, Windows, and Linux.
