VibeLLM

English | 中文

Lightweight local LLM proxy with multiple provider management, privacy protection, and automatic failover for personal use.

Features

• ✅ Lightweight: Only ~8MB install size (vs 100MB+ for litellm-proxy)
• ✅ Privacy Protection: Automatically detect PII (personal identifiable information), route simple PII to local LLM, anonymize complex PII for remote LLM and restore automatically
• ✅ Dual endpoints: Provides both OpenAI-compatible (/v1/chat/completions) and Anthropic-compatible (/v1/messages) localhost endpoints
• ✅ Multiple provider management: Add/remove/enable/disable providers with CLI
• ✅ Support local LLMs: Native support for Ollama, llama.cpp, and any OpenAI-compatible local servers
• ✅ Automatic failover: When you hit rate limit, automatically try the next provider
• ✅ Latency benchmarking: Test which provider is fastest and auto-select
• ✅ Format translation: A client configured for OpenAI can call Anthropic/Gemini, and vice versa
• ✅ Claude Code skill integration: Claude can manage providers for you

Installation

Install from PyPI (recommended)

pip install vibellm

Install from source

git clone https://github.com/easyhealth/VibeLLM.git
cd VibeLLM
pip install -e .

Quick Start

1. Add your first provider:

vibellm add \
  --name openai \
  --base-url https://api.openai.com/v1 \
  --api-key sk-xxx \
  --default-model gpt-4o

2. Start the server:

vibellm start --port 8080

3. Configure your client to use:

• OpenAI endpoint: http://localhost:8080/v1/chat/completions
• Anthropic endpoint: http://localhost:8080/v1/messages

CLI Commands

Command	Description
vibellm start	Start the proxy server
vibellm add	Add a new provider
vibellm remove	Remove a provider
vibellm list	List all providers
vibellm enable <name>	Enable a provider
vibellm disable <name>	Disable a provider
vibellm default <name>	Set default provider
vibellm test <name>	Test connectivity to a provider
vibellm benchmark	Test latency for all providers
vibellm benchmark --auto-set	Test and set fastest as default
vibellm status	Show server status

Benchmarking

Find your fastest provider:

vibellm benchmark --auto-set

This will:

1. Test all enabled providers with a simple request
2. Measure latency
3. Automatically set the fastest as the default

Claude Code Skill Installation

To use as a Claude Code skill, add this to your Claude Code skills directory:

ln -s D:/VibeLLM/vibellm-skills/llm_proxy.py ~/.config/claude-code/skills/

Then Claude can respond to natural language commands like:

• "list providers"
• "switch default to anthropic"
• "I'm rate limited, find the fastest provider"
• "benchmark and set fastest as default"
• "test my openai provider"

Configuration

Configuration is stored at ~/.config/vibellm/config.yaml:

default_provider: openai-main
providers:
  - name: openai-main
    base_url: https://api.openai.com/v1
    api_key: sk-xxx
    default_model: gpt-4o
    enabled: true
    priority: 1  # lower = higher priority for failover
    last_latency_ms: null

Selecting Specific Provider

You can select a specific provider per request using the X-LLM-Provider header:

X-LLM-Provider: anthropic
POST /v1/chat/completions

This will bypass the default and use the explicitly requested provider.

Dependencies

• Python 3.10+
• fastapi
• uvicorn
• httpx
• click

Why this vs litellm-proxy?

litellm-proxy is great for production with many features, but it's heavy and pulls in dozens of dependencies. This project is:

• For personal use on your local machine
• Much lighter weight (only 8 core dependencies vs 50+ for litellm)
• Simpler: just local config file, no database
• Focused on the specific use case: multiple API keys/providers with failover and latency selection
