June 2026 marked a turning point for AI coding tools in China. Zhipu released ZCode 3.0, Xiaomi open-sourced MiMo Code, and Huawei launched DevEco Code at HDC 2026. Developer communities are calling it the "Three Kingdoms War" of domestic AI coding tools.
These three products take fundamentally different technical approaches. This article compares them across product positioning, technical architecture, and developer experience, while exploring the unique value proposition of local-first solutions in this space.
Product Positioning
ZCode 3.0 (Zhipu AI): Released June 13, positioned as a multi-agent collaborative IDE. Core features include grouped task workspaces, Zread intelligent project knowledge base, and visual Git branch graphs. Zhipu's advantage lies in deep integration between its proprietary GLM model series and the tool itself.
MiMo Code (Xiaomi): Open-sourced June 11, built on OpenCode with MIT license. Supports persistent memory systems, unlimited context windows, and multi-model compatibility (DeepSeek, Kimi, GLM, MiMo v2.5). Xiaomi chose an open ecosystem approach.
