ZCode vs OpenCode: Features, Pricing and User Reviews 2026

ZCode is a free desktop app from Z.ai that helps you build software using an AI agent. Instead of just chatting with AI inside an editor, you tell ZCode what you want done, and it plans the work, edits your files, runs terminal commands, checks its own results, and keeps working until the task is finished.

It is built around the GLM-5.2 model, which can hold a huge amount of context so it can work on large, complex projects without losing track of details. You can also connect other AI models if you prefer.

ZCode works on Mac, Windows, and Linux, and you can even guide tasks from your phone while the agent keeps working on your computer.

OpenCode is a free, open source AI coding agent made for developers. It works in your terminal, as a desktop app, inside popular code editors, and through a local web interface.

You can talk to it in plain language to write new code, fix bugs, refactor messy code, and make sense of large codebases. Rather than just guessing, it explores your project first, plans the needed changes, and then uses tools such as file editing, search, and shell commands to finish the task.

It supports over seventy five AI model providers, from big paid services to free local models, so you can choose what fits your budget. Since it does not store your code or data, it also works well for privacy focused teams.
