Anthropic's terminal-native agentic coding tool.
Z.ai's agent-first coding IDE, built as the official harness for the GLM-5.2 model.
ZCode is Z.ai's free, cross-platform "Agentic Development Environment" — a desktop coding IDE built as the official harness for the open-weight GLM-5.2 model. Instead of line-by-line autocomplete, you set a Goal and its agent plans the work, edits files, runs checks and iterates until the task is done. It supports multi-agent collaboration on one codebase and lets you steer long-running jobs remotely from chat apps. The app is free; running it at scale uses Z.ai's GLM Coding Plans, or you can bring your own key.
The ZCode app is free to download and use. Heavy usage runs on Z.ai's GLM Coding Plans, which start around $18/month (Lite) with Pro and Max tiers for higher limits, or you can bring your own model key.
ZCode is best suited for developers who want a free, agent-first coding IDE tuned for Z.ai's GLM-5.2 open model. The main trade-off: getting the most out of it leans on a GLM Coding Plan subscription.
