Production-grade autonomous AI coding assistant with multi-agent orchestration, WebXR visualization, and zero-trust sandboxing.
🇺🇸 English | 🇯🇵 日本語 | 📖 Docs | 🚀 Quick Start | 🔖 Releases
Codex is a next-generation AI engineering platform forked from OpenAI/codex and dramatically extended with enterprise features. It transforms AI from a simple code assistant into a self-organizing, multi-agent development environment capable of autonomously designing, coding, reviewing, and testing software — with full VR/AR visualization and MCP ecosystem integration.
Built in Rust 2024 for maximum performance and memory safety. Ships with a Next.js 15 GUI (port 1919), WebSocket CLI bridge, immersive 3D Git visualization (Git4D), and a pluggable MCP server/client ecosystem.

codex delegate-parallel --agents backend,qa,frontend --task "Implement auth module"- Planner: Decomposes complex tasks into granular subtasks.
- Assigner: Routes to specialized sub-agents.
- Executor: Runs agents in parallel using isolated Git worktrees.
- Aggregator: Merges results with semantic conflict detection.
Benchmark: 2.59× average speedup over sequential execution across test cases.
Three-tier, platform-native process isolation — no userspace hacks:
| Platform | Technology | Scope |
|---|---|---|
| Windows | Win32 Job Objects + restricted token ACLs | Kernel-level |
| Linux | Landlock LSM + seccomp-bpf syscall filtering | Kernel-level |
| macOS | Seatbelt (sandbox-exec) profiles | Kernel-level |
Three modes: read-only (default) · workspace-write · danger-full-access
Codex is unique in operating as both an MCP consumer and provider:
- As a Client: Connects to external MCP servers (filesystem, git, browser, etc.).
- As a Server: Exposes its own coding capabilities to Claude, Cursor, and other AI agents.
- New in v3.0.0: Protocol alignment with latest Model Context Protocol specs.
Multi-source intelligent research — not just web search:
- Sources: DuckDuckGo + Gemini + Brave Search APIs in parallel.
- Verification: Citation tracking, cross-source fact checking.
- Output: Structured reports with confidence scores and deep-linked references.
Experience your repository in immersive 3D:
- Three.js + WebXR: Commit graph rendered in 4D space-time.
- Meta Quest 2/3: Full hand tracking support.
- Cyberpunk Aesthetics: Custom GLSL shader effects and volumetric data nodes.
- Protocol v2 Alignment: Seamless integration with the latest upstream service tiers and elicitation protocols.
- Optimized Linking Engine: Drastic reduction in binary linking time for large-scale enterprise deployments.
- Refined Approval Flow: More intuitive and granular permission management for tool execution.
- Stability: Resolved all critical lifetime and type-safety regressions from earlier v3 beta cycles.
- MILSPEC-Grade Build: Zero Rust compiler warnings across the entire 69-crate workspace.
- Enhanced Multi-Agent Capacity: Supports double the density of parallel sub-agents vs. upstream.
- Integrated Domain Skills: Native support for
/VRChat,/Blender-CAD, and/Yukkuri-Movieworkflows. - ShinkaEvolve Framework: Infrastructure for ASI self-evolution and system-wide state diffusion.
