mediaeng/llmproxy

A lightweight reverse proxy for Ollama that manages API keys with configurable token and request quotas. Incoming requests in OpenAI-compatible or Anthropic-compatible format are authenticated, checked against the quota, and forwarded to the configured Ollama server.

Features

OpenAI-compatible endpoint (/v1/chat/completions, /v1/models)
Anthropic Messages API (/v1/messages) — compatible with Claude Code CLI and Anthropic SDK clients
API key management with daily and monthly token/request limits
Web-based admin interface (port 8001)
Model lock: enforces a specific model for all requests (useful for courses and lab sessions)
Streaming support (Server-Sent Events)
Tool use / function calling passthrough
Rotating usage logs
SQLite (default) or PostgreSQL

Ports

Port	Service
`8000`	Proxy endpoint (OpenAI and Anthropic API)
`8001`	Admin API + web interface

All API endpoints require the ADMIN_PASSWORD — without a valid token, only the public frontend files (HTML/JS/CSS of the login page) are accessible. The password is therefore the primary protection.

Environment Variables

Variable	Default	Description
`ADMIN_PASSWORD`	–	Required. Password for the admin interface
`OLLAMA_URL`	`http://localhost:11434`	URL of the Ollama server (without `/v1` suffix)
`DATABASE_URL`	`sqlite:///./test.db`	Database connection string (SQLite or PostgreSQL)
`PROXY_HOST`	`0.0.0.0`	Proxy bind address
`PROXY_PORT`	`8000`	Proxy port
`ADMIN_HOST`	`0.0.0.0`	Admin API bind address (`127.0.0.1` to restrict to local access)
`ADMIN_PORT`	`8001`	Admin API port
`APP_TZ`	`Europe/Berlin`	Timezone for daily/monthly quota resets
`LOG_FILE`	`logs/usage.log`	Path of the rotating usage log file
`ANTHROPIC_DEFAULT_MODEL`	–	Default model for `/v1/messages` (Ollama model name, e.g. `llama3`)

Docker Compose – Ollama on the Host (Linux, recommended)

network_mode: host gives the container direct access to the host network stack. Ollama runs on the host and is reachable at localhost:11434 — not visible from outside. The proxy and admin interface are available directly on host ports 8000 and 8001.

Client Configuration

OpenAI-compatible client:

Base URL:  http://<host>:8000/v1
API Key:   <API key created in the admin interface>

Claude Code CLI:

ANTHROPIC_BASE_URL=http://<host>:8000 \
ANTHROPIC_AUTH_TOKEN=<API key> \
claude

Acknowledgements

The Anthropic Messages API endpoint (/v1/messages) was inspired by free-claude-code by Ali Khokhar, which pursues a similar approach for routing Claude Code requests to alternative LLM backends.
