Deploy and Host OmniRoute Hardened AI Gateway on Railway

OmniRoute is an open-source (MIT) AI gateway: one OpenAI-compatible endpoint in front of hundreds of LLM providers, with combos, quota-aware fallback, prompt compression, per-app API keys and a web dashboard. It works with Claude Code, Codex, Cursor, Cline and any OpenAI SDK.

About Hosting OmniRoute Hardened AI Gateway

This template runs the official OmniRoute v3.8.51 image, pinned by digest to the tag build that fixes CVE-2026-88062 (a critical remote code execution in the ACP custom-agent endpoint). The plain 3.8.51 and latest tags currently resolve to an older pre-release on amd64, which is why the digest pin matters. A Railway volume at /app/data holds the SQLite database, so providers, keys and settings survive redeploys, and Railway health checks /healthz on port 20128.

Security is on from the first request. The admin password is generated and seeded at boot, so there is no open setup window. Every /v1 call needs an API key, and one is generated for you. On first boot the template also blocks every keyless provider OmniRoute would otherwise route with zero setup (several of them scrape consumer web apps) and keeps auto combos away from providers upstream flags as terms-of-service risks. Nothing routes until you add a provider with your own key.

Common Use Cases

One endpoint for every model: OpenAI, Anthropic, Gemini, OpenRouter, Groq, DeepSeek, Mistral and more behind a single base URL
Coding agents: point Claude Code, Codex, Cursor or Cline at your gateway with one key
Fallback and load balancing: combos that retry across providers and accounts when quotas run out
Per-app keys: separate API keys with model restrictions and usage limits
Private gateway for other Railway services: keep provider keys out of your app containers

Dependencies for OmniRoute Hardened AI Gateway Hosting

Railway volume at /app/data (included)
Provider API keys: your own, added in the dashboard after deploy (none are bundled or enabled)
Hobby plan or higher: OmniRoute needs about 2 GB of RAM

Deployment Dependencies

Implementation Details

Key variables (secrets are generated at deploy):

PORT=20128
OMNIROUTE_HOSTNAME=::
DATA_DIR=/app/data
RAILWAY_RUN_UID=0
INITIAL_PASSWORD=${{secret(32)}}
REQUIRE_API_KEY=true
OMNIROUTE_API_KEY=sk-${{secret(48)}}
JWT_SECRET=${{secret(64)}}
API_KEY_SECRET=${{secret(64,"abcdef0123456789")}}
STORAGE_ENCRYPTION_KEY=${{secret(64,"abcdef0123456789")}}
OMNIROUTE_PUBLIC_BASE_URL=https://${{RAILWAY_PUBLIC_DOMAIN}}
AUTH_COOKIE_SECURE=true

First steps after deploy

Wait for /healthz to return ok.
Open your Railway domain and sign in with INITIAL_PASSWORD from the service variables. Anonymous visitors cannot reach the dashboard or the management API.
Add a provider under Providers with your own API key.
Call https:///v1/chat/completions with Authorization: Bearer , or create per-app keys under API Keys.

Keep Require login on, keep one replica (SQLite), and never rotate STORAGE_ENCRYPTION_KEY or API_KEY_SECRET after first boot. If you add a custom domain, update OMNIROUTE_PUBLIC_BASE_URL and NEXT_PUBLIC_BASE_URL. Web-session providers (pasted browser cookies for consumer chat apps) and subscription OAuth providers are available in the dashboard but likely break those services' terms; the template enables none of them.
