LocalGateway

Desktop LLM gateway with multi-provider failover and automatic model name mapping.

pip install local-gateway

# Set your API keys
export DEEPSEEK_API_KEY=sk-...
export KIMI_API_KEY=sk-...

# Start the gateway
local-gateway --providers deepseek,kimi

Why?

Every desktop AI tool (Cursor, Claude Desktop, Windsurf, Continue.dev) lets you configure one API endpoint. If that provider goes down, your tool stops working.

LocalGateway is a lightweight proxy that sits between your desktop tools and LLM providers. It tries providers in sequence — if the first one fails, it automatically falls back to the next.

The Model Name Problem

Model names are not portable across providers:

| Your Request | DeepSeek | KIMI | |-------------|----------|------| | deepseek-chat | ✅ works | ❌ 404 — KIMI doesn't know this name | | gpt-4o | ❌ doesn't exist | ❌ doesn't exist |

LocalGateway solves this with a cross-provider model name mapping table. When falling back from DeepSeek to KIMI, it automatically maps deepseek-chat → moonshot-v1-128k.

Usage

# Two providers (DeepSeek → KIMI auto-failover)
local-gateway --providers deepseek,kimi

# Three providers
local-gateway --providers deepseek,kimi,openai

# Custom port
local-gateway --providers deepseek,kimi --port 8080

# Explicit API keys (instead of env vars)
local-gateway --providers deepseek,kimi \
  --api-key deepseek=sk-xxx \
  --api-key kimi=sk-yyy

# Listen on all interfaces (for Docker/LAN)
local-gateway --providers deepseek,kimi --host 0.0.0.0

Configuration

Environment Variables

| Provider | Env Variable | |----------|-------------| | DeepSeek | DEEPSEEK_API_KEY | | KIMI | KIMI_API_KEY | | OpenAI | OPENAI_API_KEY | | Anthropic | ANTHROPIC_API_KEY | | Groq | GROQ_API_KEY | | Together | TOGETHER_API_KEY | | Mistral | MISTRAL_API_KEY | | Google Gemini | GOOGLE_API_KEY | | OpenRouter | OPENROUTER_API_KEY |

Using with any OpenAI-compatible client

import openai
client = openai.OpenAI(
    base_url="http://127.0.0.1:18790/v1",
    api_key="not-needed",  # local-gateway doesn't validate the client key
)

How It Works

                    ┌─────────────────┐
Client ──POST──→  local-gateway      │
                    │                  │
                    ├→ try DeepSeek ──→ HTTP 200 → forward response
                    │                  │
                    └→ DeepSeek fails  │
                      → try KIMI ────→ HTTP 200 → forward response
                                       │
                         all fail ────→ 502

For SSE streaming, the proxy connects to the upstream before sending HTTP 200 to the client. This means failover is transparent — the client never sees a partial response.
