LiteLLM Gateway — Cloudron App

A Cloudron app package for LiteLLM, the open-source AI gateway, configured for the Inference Cooperative.

LiteLLM is the single gateway between members and the inference backends. It handles per-member API keys, usage metering, rate limiting (via budget caps), and model routing — all behind one OpenAI-compatible endpoint.

What this provides

• LiteLLM proxy with an OpenAI-compatible API on port 4000
• Per-member virtual API keys with budget caps and rate limits
• Usage / spend tracking per key, per model
• Model routing to Tinfoil (TEE-protected inference)
• Cloudron PostgreSQL for keys, teams, and spend logs
• Cloudron Redis for rate limiting and caching
• Automatic SSL, backups, and sandboxing (Cloudron-managed)
• Master key + salt key auto-generated on first start, persisted in /app/data

Architecture

Members → Open WebUI / LobeChat → LiteLLM (this app) → Tinfoil (TEE)

LiteLLM is the control plane (keys, metering, routing). It does not run models itself — it forwards to Tinfoil, which runs open models inside trusted execution environments (TEEs).

Files

• CloudronManifest.json — Cloudron app manifest (addons, ports, metadata)
• Dockerfile — wraps LiteLLM's official image for Cloudron's environment
• start.sh — startup script that wires up Cloudron's Postgres/Redis and writes the default config
• config.yaml — default LiteLLM config (Tinfoil-only, two models)
• logo.png — app icon

Models (MVP)

Two models, both TEE-protected via Tinfoil:

Model	Role	Price (in/out per M tokens)
deepseek-v4-flash	Default — best agent performance, 1M context	$0.30 / $0.70
gpt-oss-120b	Fallback — cheapest, built for agentic workflows	$0.15 / $0.60

If DeepSeek is down, LiteLLM automatically falls back to GPT-OSS.

Building and installing

This package uses Cloudron's on-server build (no local Docker, no registry). The Cloudron CLI uploads the source and Cloudron builds the image on the server.

Prerequisites

• The Cloudron CLI installed on a machine with access to the Cloudron server
• A Cloudron instance with the inference.coop domain

Install

# 1. Install the Cloudron CLI (once)
npm install -g cloudron-cli

# 2. Log in to the Cloudron
cloudron login my.inference.coop

# 3. From this directory, install (builds on the server)
cloudron install --location gateway

--location gateway installs the app at gateway.inference.coop. Omit --location to be prompted.

Configure

After install, set the Tinfoil API key in Cloudron → app → Settings → Environment Variables:

• TINFOIL_API_KEY — your Tinfoil API key (from https://tinfoil.sh/)

The following are auto-generated and should not be set manually:

• LITELLM_MASTER_KEY — generated on first start, stored in /app/data/.master_key
• LITELLM_SALT_KEY — generated on first start, stored in /app/data/.salt_key
• DATABASE_URL — from Cloudron's PostgreSQL addon
• REDIS_HOST, REDIS_PORT, REDIS_PASSWORD — from Cloudron's Redis addon

Access the admin UI

1. Open https://gateway.inference.coop/ui
2. Log in with username admin and the master key as password
3. Find the master key: cloudron exec --app <app-id> cat /app/data/.master_key

Updating LiteLLM

This is the routine maintenance path. LiteLLM releases frequently; updating is a two-step change.

1. Bump the base image tag

In Dockerfile, change the pinned version:

FROM ghcr.io/berriai/litellm:main-v1.74.0-stable
#                              ^^^^^^ bump this

2. Bump the manifest version

In CloudronManifest.json, update:

"version": "1.0.0",
"upstreamVersion": "1.74.0"

3. Redeploy

cloudron update --app <app-id>

Cloudron rebuilds from source and applies the update. Data (keys, spend logs) persists in PostgreSQL.

Before updating

• Check the LiteLLM changelog for breaking changes
• The start.sh and config.yaml may need adjustment if LiteLLM changes its env-var or config schema
• Test on a staging instance if the version jump is large

Environment variables

Variable	Required	Purpose
TINFOIL_API_KEY	Yes	Tinfoil API key for TEE inference

Connecting Open WebUI

In Open WebUI settings:

• API Base URL: https://gateway.inference.coop/v1
• API Key: a virtual key created in LiteLLM's Admin UI

OIDC / SSO (future)

The current package uses LiteLLM's built-in admin/master-key auth, which is sufficient for the MVP. Full OIDC SSO (admin UI behind Cloudron login) is a TODO — add the "oidc": {} addon to the manifest and configure LiteLLM's SSO hooks per https://docs.litellm.ai/docs/proxy/custom_sso.
