Deploy and Host self hosted OmniRoute Gemini CLI (Self-Hosted AI Routing for Gemini Clients) on Railway

This template runs OmniRoute as one Railway service with a persistent volume. Built for developers who want Gemini-style tooling on one OpenAI-compatible endpoint they host.

About Hosting OmniRoute Gemini CLI open-source software on Railway (self hosted self-hosted OpenAI-compatible AI router for Gemini CLI template)

This template runs one Railway service from the pinned diegosouzapw/omniroute:3.8.51 image on port 20128, with a volume at /app/data.

Railway handles the build, public HTTPS domain, restarts, and volume. The template generates the dashboard password and secrets for you.

Why Deploy OmniRoute Gemini CLI, the OpenRouter alternative on Railway (Railway Free Trial)

OpenRouter keeps your traffic, keys and routing on their side and adds their markup on each model.

Railway is a singular platform to deploy your infrastructure stack. Railway will host your infrastructure so you don't have to deal with configuration, while allowing you to vertically and horizontally scale it.

By deploying OmniRoute Gemini CLI on Railway, you are one step closer to supporting a complete full-stack application with minimal burden. Host your servers, databases, AI agents, and more on Railway.

Railway vs Other Hosting Providers and VPS for OmniRoute Gemini CLI self hosting

Here is how a Railway deploy compares with running the same OmniRoute container yourself.

Provider	What You Get with Railway	What You Get with the Other Provider
DigitalOcean	A one-click template with the pinned OmniRoute image, a volume at /app/data, and generated secrets.	A droplet you configure yourself, including Docker, firewall, and TLS.
AWS	A single service with a public domain and /healthz checks, with no VPC or load balancer setup.	Fine-grained networking and scaling, with a steeper setup for a small gateway.
Hetzner	A managed deploy with the service, domain, and volume wired together.	Low-cost raw servers that suit steady workloads, but you maintain the container and backups.

Either path works, so pick based on how much server care you want to take on.

Common Use Cases for hosted OmniRoute Gemini CLI

Testing one base URL across providers: Point your client at a single OpenAI-compatible endpoint and swap models behind it. The docs confirm http://localhost:20128/v1 with a Bearer key as the entry point.
One key for coding agents: Give your tools one OmniRoute key instead of a separate key per vendor. You still bring your own provider accounts.
Auto routing as a starting point: Model auto needs no model choice up front. It only works once at least one eligible provider is connected.
Comparing against a direct Gemini API key: Run the same prompt through OmniRoute and through Google's API to see how latency and failures differ.
Keeping logs on your own infrastructure: Request history stays in SQLite on your Railway volume at /app/data, not on a hosted gateway you don't control.

Dependencies for OmniRoute Gemini CLI Docker hosted on Railway

This section covers what the Railway template runs and what you need before it works. The template is a single service with no separate database or cache.

Deployment Dependencies for Managed OmniRoute Gemini CLI Service (AI Gateway)

You need a Railway account and at least one upstream provider account you are allowed to use.

Implementation Details for OmniRoute Gemini CLI (Using OmniRoute official docker image)

The service runs diegosouzapw/omniroute:3.8.51 on port 20128, with health at /healthz, the dashboard at /dashboard, and the API at /v1.

How does OmniRoute Gemini CLI compare against other ways to route Gemini CLI traffic through a gateway

Gemini CLI can call Google's Gemini API directly, and OmniRoute adds a routed, OpenAI-compatible endpoint in front of your tools. The points below stick to what the upstream docs confirm.

OmniRoute Gemini CLI vs Gemini API direct (Google AI Studio key)

Setup path: Gemini CLI reads GEMINI_API_KEY and talks to Google with no middle layer. OmniRoute adds a service you run.
Model scope: Direct access gives you Google's models and quotas. OmniRoute routes across many providers behind one base URL.
Where direct wins: If you only want Gemini models and no server to maintain, the direct API is simpler.

OmniRoute Gemini CLI vs OpenRouter (hosted gateway)

Hosting: OpenRouter is fully managed. OmniRoute runs on your own Railway service or VPS, with data in a volume you control.
Keys and data: OmniRoute encrypts provider keys at rest in SQLite on your server.
Where OpenRouter wins: Less work if you don't want to handle uptime, updates, or memory limits yourself.

OmniRoute Gemini CLI vs LiteLLM (open-source proxy)

Shape: LiteLLM is a Python proxy and SDK. OmniRoute is a Node gateway with a dashboard and routing built in.
Ops footprint: OmniRoute keeps everything in SQLite inside one container, with no Postgres or Redis to add.
Where LiteLLM wins: If you already run Python infrastructure and want an embeddable library, it fits better.

OmniRoute Gemini CLI vs 9Router (same-category self-hosted router)

Category: 9Router is another self-hosted AI router, so the choice comes down to dashboard, routing options, and provider coverage.
Feature check: OmniRoute claims 372 providers and 19 routing strategies. Verify those against current docs before relying on them.
Where 9Router may win: If its provider list or deployment model matches your stack more closely, it's the better pick.

How to use OmniRoute Gemini CLI (the OSS AI gateway)?

First-day steps after the Railway deploy. The template runs diegosouzapw/omniroute:3.8.51 on port 20128 with a volume at /app/data.

Deploy the Railway template and wait for the service to go healthy.
Open the public domain and sign in at /dashboard.
Create an API key under Dashboard > Endpoints.
Confirm the service is up at /healthz.
Connect at least one eligible provider, since model "auto" needs one.
Test the endpoint:

curl http://localhost:20128/v1/chat/completions \
  -H "Authorization: Bearer YOUR_OMNIROUTE_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model": "auto", "messages": [{"role": "user", "content": "ping"}]}'

export GEMINI_API_KEY="YOUR_GEMINI_API_KEY"

Gemini CLI is configured separately in ~/.gemini/settings.json:

{
  "selectedAuthType": "gemini-api-key"
}

Pointing Gemini CLI at the OmniRoute base URL is not confirmed by the docs, so verify that step yourself.

How to self host OmniRoute Gemini CLI on other VPS Services (OmniRoute self hosting guide)

Running OmniRoute on your own VPS gives you the same single OpenAI-compatible endpoint the Railway template provides, but you manage the process yourself.

Clone the Repository

Pull the source from the upstream project and move into the folder.

git clone https://github.com/diegosouzapw/omniroute.git
cd omniroute

Install Dependencies

Install packages with your Node toolchain, or use the official Docker image if you prefer containers.

npm install

Configure Environment Variables

Create a local env file so the app keeps its data directory and secrets across restarts. Replace the values with your own.

PORT=20128
DATA_DIR=/app/data
BASE_URL=https://your-domain
NEXT_PUBLIC_BASE_URL=https://your-domain
REQUIRE_API_KEY=true

Start the OmniRoute Gemini CLI Application

Start the app, then open the dashboard and create an API key under Endpoints. Put the public URL behind HTTPS so the dashboard cookie is secure.

npm run dev

Railway handles the domain, HTTPS, volume and restarts for you, which is the part you otherwise maintain yourself on a VPS.

Official Pricing of OmniRoute Gemini CLI (OmniRoute pricing)

OmniRoute is MIT licensed and free to use, so there is no subscription fee to pay the project itself.

Frequently Asked Questions (FAQs)

Does OmniRoute officially support Gemini CLI as a client?

No Gemini CLI section appears in the upstream docs I checked, so support isn't confirmed.

Can Gemini CLI use OmniRoute as a provider?

The docs show no config key or env var for that. Gemini CLI reads GEMINI_API_KEY for its own Gemini API path, so treat any OmniRoute wiring as something you'd have to test yourself.

What base URL and API key does OmniRoute expose?

Locally it's http://localhost:20128/v1, and on Railway it's your public domain plus /v1.

How do model mapping and fallbacks work with auto and combos?

Setting the model to auto gives zero-config routing, with variants like auto/coding and auto/fast.

Why does auto return no models on a fresh install?

Auto needs at least one eligible connected provider, and a fresh install usually has none. Providers marked tos: avoid, such as Kiro, are excluded by default, even when connected.

How does OmniRoute compare with the Gemini API direct, OpenRouter and LiteLLM?

The Gemini API direct uses Google's own quotas with no gateway layer.
