Our Bold Vision·
Let every person with an idea
become a true creator
Some people's minds are overflowing with ideas,
but are blocked by a wall called "code"
Who has the right to create?
From today, the answer is only one — everyoneNo need to know code
No technical background required
All you need is an idea
FuxiCode handles the restFree forever. For everyone. Without exception
Because the right to create belongs to all
All You Need Is an Idea — Start TodayNo coding skills required, just plain text input. Permanently free for individuals and teams, with no discrimination or usage limits.

FUXI·Intelligent Routing Layer
Four Exclusive Strategies, Two Deep Enhancements —— AI Speed at Its PeakCompetitors wait single-point. fuxicode runs 4 engines: faster, cheaper, context never lost
Racer Parallel Race
INDUSTRY FIRST
·Race up to3 providersin parallel — first response wins
·30–60%faster in high-latency environments
·Check results via GetLastResult ( )
CostRouter
AUTO COST SAVER
·0–100 complexity scorefor every request
·Routes tofree / cheap / standard / premium
·Simple questions free, complex tasks upgraded
SelfPack Memory
MULTI-DAY CONTEXT
·InjectsGoals / Stage / KeyFactsevery turn
·Stage: exploring / implementing / testing / planning
·Persisted state — AI never loses context
Failover
ALWAYS A BACKUP
·Auto-switch on429 / 5xxerrors
·60s cooldowncircuit breaker per provider
·Streaming failover — no interruption felt
ThinkingProvider · Reasoning Chain InjectionThree strategies, auto-selected by model capabilities:native — Claude / o-series / DeepSeek native reasoning
prompt_inject — ASR adaptive prompt injection
two_phase — reason first, then answerEffort levels: low / medium / high / max, unleashing deep thinking potential.
CompactViaForkAgent · Ultra-Long Context CompressionIntelligent compression via fork path + prompt cache sharing – goodbye manual truncation.Anthropic models use optimal fork paths; other providers degrade gracefully.Source: internal/engine/
FUXI · Application Scenarios
Every Development Scenario, FuXi Is ReadyFrom personal projects to enterprise R&D, on‑prem to cloud integration, FuxiCode covers developers' core workflows.
Multi‑Model Parallel Debugging
Powered by Racer
Race DeepSeek, Qwen, and Moonshot simultaneously on the same bug; the first optimal solution wins. No more model‑selection hesitation.
Long‑Cycle Project Development
Powered by SelfPack
For cross‑day/cross‑week complex tasks, AI retains your goals, current phases, and key decisions. Resume work seamlessly from yesterday when opening the terminal next day.
Cost‑Controlled Team R&D
Powered by CostRouter
Simple tasks auto‑use free models; premium models are only called for complex architecture design. Teams save far more on daily API costs than expected.
CI/CD Pipeline Integration
Powered by Hook System
40+ Hook events enable deep AI integration into your workflow — AI auto‑intervenes at every stage: code commit, test failure, deployment completion.
Security‑Sensitive Code Development
Powered by Security Architecture
In finance, healthcare and government scenarios, all AI‑executed commands undergo AST‑level security checks. Enable AI‑assisted development while blocking risks.
On‑Premises Private Deployment
Powered by Local Provider
Integrate with Ollama, vLLM or LM Studio. All code and data run in local closed‑loop mode, never leaving the intranet. Suitable for strict compliance scenarios.

FUXI · Security Architecture
Code Security, Zero CompromiseFour‑layer security fully deployed, AST‑grade deep defense — FuxiCode self‑built security system for real code & data protection
Bash AST Secure ExecutionAST syntax-level inspection blocks 27 risk patterns. Rather than simple string filtering, it truly interprets your commands before authorizing execution.
Path Traversal ProtectionComplete symbolic link parsing + whitelist-based path validation, even mitigating TOCTOU race conditions.FuXi safeguards the boundaries of your file system.
MCP Security IsolationMCP tools run within strict sandboxes with triple isolation: 30-second timeout, resource limits, and protocol boundary controls.No external tool can cross the boundaries defined by FuXi.
File Operation RestrictionsAtomic write operations prevent data loss; API keys are automatically desensitized without leaving traces.
