📌 What is JeikCode?

JeikCode is a next-generation, cross-platform, full-featured open-source AI Coding Agent built natively in pure Rust. Designed specifically for high-complexity production software engineering, it delivers extreme lightweight speed, complete control, and end-to-end multi-device workflows:

• 🔍 Semantic CodeGraph (CodeExplore): Powered by Tree-Sitter across 12+ programming languages. Seamlessly integrates domain bilingual thesauruses (thesaurus) to query code using everyday business natural language, backed by 1~3ms zero-touch incremental patching;
• 🛡️ 98–99% KV-Cache Protection (Sacred Floor): Enforces strict append-only byte immutability and memory preservation (sacred_floor), keeping system prefixes frozen across turns. Completely eliminates cache thrashing, slash token expenses by over 90%, and compresses TTFT to milliseconds;
• ⚡ 9k Minimal Prompts & High Discipline: Avoids 30–50k token system bloat. A standard greeting turn consumes only ~9–11k tokens, reserving the maximum context window strictly for your codebase. Fully open-source and live-reloadable;
• 📱 Omni-Platform Workflows & Mobile UI: Full coverage across terminal TUI, modern WebUI, Tauri desktop apps, and headless background daemons. WebUI is specifically optimized for phone and tablet touchscreens for on-the-go coding;
• 🔒 Git-like State Machine Atomic Protection: Strict concurrent file edit boundaries eliminate dirty writes. Operates safely across frontier and lightweight models, complete with one-click undo/rollback checkpoints;
• 🔄 Native Support for 5 Industry Protocols: Seamlessly integrates OpenAI Chat, OpenAI Responses, Anthropic Claude, Google Gemini, and Ollama formats, with complete decoupling of accounts and models;
• 🧩 Tri-Protocol Gateway & Open Ecosystem: Exposes standard OpenAI, Anthropic, and Gemini compatible server endpoints, enabling tools like OpenClaw or translation plugins to connect effortlessly;
• 🚀 Rapid Iterations & Agile Code Review: Community issues and PRs are reviewed and merged with extreme velocity, accompanied by fast pre-release beta builds.
