Audit: Removed / Dead Variables

1. Required Secrets

These must be set before the first run. Without them, the application will either refuse to start or operate with insecure defaults.

Variable	Required	Default	Source File	Description
`JWT_SECRET`	Yes	(none)	`src/lib/auth`	Signs/verifies all dashboard session cookies (JWT). Generate with `openssl rand -base64 48`.
`API_KEY_SECRET`	Yes	(none)	`src/lib/db/apiKeys.ts`	AES encryption key for API key values at rest in SQLite. Generate with `openssl rand -hex 32`.
`INITIAL_PASSWORD`	Yes	`123456`	Bootstrap script	Sets the initial admin dashboard password. Change before first use. After login, change via Dashboard → Settings → Security.

Generation Commands

# Generate all three secrets at once:
echo "JWT_SECRET=$(openssl rand -base64 48)"
echo "API_KEY_SECRET=$(openssl rand -hex 32)"
echo "INITIAL_PASSWORD=$(openssl rand -base64 16)"

Caution

Never commit .env files with real secrets to version control. The .gitignore already excludes .env, but verify before pushing.

2. Storage & Database

OmniRoute uses SQLite (via better-sqlite3) for all persistence. These variables control data location, encryption, and lifecycle.

Variable	Default	Source File	Description
`DATA_DIR`	`~/.omniroute/`	`src/lib/db/core.ts`	Root directory for SQLite DB, backups, and data files. Override for Docker volumes or custom paths.
`STORAGE_ENCRYPTION_KEY`	(empty = disabled)	`src/lib/db/encryption.ts`	AES key for full SQLite database encryption at rest. Generate with `openssl rand -hex 32`.
`STORAGE_ENCRYPTION_KEY_VERSION`	`v1`	`scripts/bootstrap-env.mjs`, `electron/main.js`	Version label for the encryption key. Increment when performing key rotation to support decryption of old backups.
`DISABLE_SQLITE_AUTO_BACKUP`	`false`	`src/lib/db/backup.ts`	When `true`, skips the automatic database backup that runs before migrations on every startup.
`OMNIROUTE_CRYPT_KEY`	(unset)	`src/lib/db/encryption.ts`	Legacy alias for `STORAGE_ENCRYPTION_KEY`. Accepted as a fallback when the primary variable is absent.
`OMNIROUTE_API_KEY_BASE64`	(unset)	`src/lib/db/encryption.ts`	Legacy alias (Base64-encoded form) accepted as a fallback. Decoded automatically before use.

Scenarios

Scenario	Configuration
Local development	Leave all defaults. DB lives at `~/.omniroute/omniroute.db`.
Docker	`DATA_DIR=/data` + mount a volume at `/data`.
Encrypted at rest	Set `STORAGE_ENCRYPTION_KEY` + keep backups of the key! Losing it = losing data.
CI/Testing	`DATA_DIR=/tmp/omniroute-test` — ephemeral, no encryption needed.

3. Network & Ports

Variable	Default	Source File	Description
`PORT`	`20128`	`src/lib/runtime/ports.ts`	Primary port for both Dashboard UI and API endpoints (single-port mode).
`API_PORT`	(unset)	`src/lib/runtime/ports.ts`	When set, serves the `/v1/*` proxy API on this separate port.
`API_HOST`	`0.0.0.0`	`src/lib/runtime/ports.ts`	Bind address for the API port.
`DASHBOARD_PORT`	(unset)	`src/lib/runtime/ports.ts`	When set, serves the Dashboard UI on this separate port.
`PROD_DASHBOARD_PORT`	`20130`	`docker-compose.prod.yml`	Host-side published port for the Dashboard in Docker production mode.
`PROD_API_PORT`	`20131`	`docker-compose.prod.yml`	Host-side published port for the API in Docker production mode.
`OMNIROUTE_PORT`	(unset)	`src/lib/runtime/ports.ts`	Takes precedence over `PORT` when running inside Electron or other wrappers.
`NODE_ENV`	`production`	Next.js core	Controls logging verbosity, caching, error detail exposure, and Next.js optimizations.

4. Security & Authentication

Variable	Default	Source File	Description
`MACHINE_ID_SALT`	`endpoint-proxy-salt`	`src/lib/auth`	Salt combined with hardware identifiers for machine fingerprinting. Change per-deployment for isolation.
`AUTH_COOKIE_SECURE`	`false`	`src/lib/auth`	Sets the `Secure` flag on session cookies. Must be `true` when running behind HTTPS.
`REQUIRE_API_KEY`	`false`	API middleware	When `true`, all `/v1/*` proxy requests must include a valid API key.
`ALLOW_API_KEY_REVEAL`	`false`	Dashboard providers page	Allows revealing full API key values in the Dashboard UI. Security risk on shared instances.
`NO_LOG_API_KEY_IDS`	(empty)	`src/lib/compliance/index.ts`	Comma-separated API key IDs that bypass request logging (GDPR compliance).
`MAX_BODY_SIZE_BYTES`	`10485760` (10 MB)	`src/shared/middleware/bodySizeGuard.ts`	Maximum allowed request body size. Rejects payloads exceeding this limit.

`OUTBOUND_SSRF_GUARD_ENABLED`	`true`	`src/shared/network/outboundUrlGuard.ts`	Block provider calls targeting private/loopback/link-local IP ranges. Disable only in isolated test envs.

Hardening Checklist

# Production security minimum:
AUTH_COOKIE_SECURE=true        # Requires HTTPS
REQUIRE_API_KEY=true           # Authenticate all proxy calls
ALLOW_API_KEY_REVEAL=false     # Never expose keys in UI
CORS_ORIGIN=https://your.domain.com
MAX_BODY_SIZE_BYTES=5242880    # 5 MB limit

5. Input Sanitization & PII Protection

OmniRoute provides a two-layer defense: request-side injection scanning and response-side PII stripping.

Request-Side: Prompt Injection Guard

Variable	Default	Source File	Description
`INPUT_SANITIZER_ENABLED`	`false`	`src/middleware/promptInjectionGuard.ts`	Enable scanning of incoming messages for prompt injection patterns.
`INPUT_SANITIZER_MODE`	`warn`	`src/middleware/promptInjectionGuard.ts`	`warn` = log only, `block` = reject request with 400, `redact` = strip suspicious patterns.
`INJECTION_GUARD_MODE`	(unset)	`src/middleware/promptInjectionGuard.ts`	Legacy alias for `INPUT_SANITIZER_MODE` — same behavior.
`PII_REDACTION_ENABLED`	`false`	`src/middleware/promptInjectionGuard.ts`	Detect PII (emails, phones, SSNs) in incoming requests.

Response-Side: PII Sanitizer

Variable	Default	Source File	Description
`PII_RESPONSE_SANITIZATION`	`false`	`src/lib/piiSanitizer.ts`	Scan LLM responses for leaked PII before returning to client.
`PII_RESPONSE_SANITIZATION_MODE`	`redact`	`src/lib/piiSanitizer.ts`	`redact` = mask PII, `warn` = log only, `block` = drop entire response.

Scenarios

Scenario	Configuration
Enterprise compliance	`INPUT_SANITIZER_ENABLED=true`, `INPUT_SANITIZER_MODE=block`, `PII_REDACTION_ENABLED=true`, `PII_RESPONSE_SANITIZATION=true`
Monitoring only	`INPUT_SANITIZER_ENABLED=true`, `INPUT_SANITIZER_MODE=warn` — logs but never blocks
Personal use	Leave all disabled — zero overhead

6. Tool & Routing Policies

Variable	Default	Source File	Description
`TOOL_POLICY_MODE`	`disabled`	`src/lib/toolPolicy.ts`	Controls LLM tool/function-calling access. `allowlist` = only listed tools, `denylist` = all except listed, `disabled` = no restrictions.

7. URLs & Cloud Sync

Variable	Default	Source File	Description
`BASE_URL`	`http://localhost:20128`	`src/lib/cloudSync.ts`	Server-side URL for internal sync jobs to call `/api/sync/cloud`.
`CLOUD_URL`	(empty)	`src/lib/cloudSync.ts`	Cloud relay endpoint URL (premium feature).
`CLOUD_SYNC_TIMEOUT_MS`	`12000`	`src/lib/cloudSync.ts`	HTTP timeout for cloud sync requests.
`NEXT_PUBLIC_BASE_URL`	`http://localhost:20128`	OAuth, Dashboard, sync	Public-facing URL for OAuth redirect_uri, Dashboard links. Must match your public URL behind reverse proxy.
`NEXT_PUBLIC_CLOUD_URL`	(empty)	Client-side	Client-side mirror of `CLOUD_URL`.
`NEXT_PUBLIC_APP_URL`	(unset)	`src/shared/services/cloudSyncScheduler.ts`	Legacy fallback for `NEXT_PUBLIC_BASE_URL`.

Important

When deploying behind a reverse proxy (nginx, Caddy), NEXT_PUBLIC_BASE_URL must be set to your public URL (e.g., https://omniroute.example.com). Without this, OAuth callbacks will fail because the redirect_uri won't match.

8. Outbound Proxy

Route upstream LLM provider calls through an HTTP or SOCKS5 proxy for egress control, geo-routing, or IP masking.

Variable	Default	Source File	Description
`ENABLE_SOCKS5_PROXY`	`true`	`open-sse/executors`	Enable SOCKS5 proxy agent for upstream calls.
`NEXT_PUBLIC_ENABLE_SOCKS5_PROXY`	`true`	Client-side	Client-side awareness of SOCKS5 availability.

`HTTPS_PROXY`	(unset)	Node.js standard	HTTPS proxy for upstream calls.
`ALL_PROXY`	(unset)	Node.js standard	Universal proxy (supports `socks5://`).
`NO_PROXY`	(unset)	Node.js standard	Comma-separated hostnames/IPs to bypass the proxy.
`ENABLE_TLS_FINGERPRINT`	`false`	`open-sse/executors`	Spoof TLS fingerprint using wreq-js (mimics Chrome 124). Counters JA3/JA4 blocking.

Corporate HTTP proxy	`HTTP_PROXY=http://proxy.corp.com:3128`, `HTTPS_PROXY=http://proxy.corp.com:3128`, `NO_PROXY=localhost,internal.corp.com`
Anti-fingerprint	`ENABLE_TLS_FINGERPRINT=true` — requires `wreq-js` (included)

9. CLI Tool Integration

Controls how OmniRoute discovers and launches CLI sidecars (Claude Code, Codex, etc.).

Variable	Default	Source File	Description
`CLI_MODE`	`auto`	`src/shared/services/cliRuntime.ts`	`auto` = search system PATH; `manual` = use explicit paths only.

Variable	Provider	Notes
`CLAUDE_OAUTH_CLIENT_ID`	Claude Code (Anthropic)	Public client — no secret needed.
`CLAUDE_CODE_REDIRECT_URI`	Claude Code	Override redirect URI. Default: `https://platform.claude.com/oauth/code/callback`
`CODEX_OAUTH_CLIENT_ID`	Codex / OpenAI	Public client.
`GEMINI_OAUTH_CLIENT_ID`	Gemini (Google)	Requires matching `_SECRET`.
`GEMINI_OAUTH_CLIENT_SECRET`	Gemini (Google)	—

`QODER_CLI_WORKSPACE`	Qoder	Workspace ID for Qoder CLI.
`OMNIROUTE_QODER_WORKSPACE`	Qoder	Alias for `QODER_CLI_WORKSPACE`.

Warning

Google OAuth (Antigravity, Gemini CLI) credentials only work on localhost. For remote servers:

Go to Google Cloud Console → Credentials
Create an OAuth 2.0 Client ID (type: "Web application")
Add your server URL as Authorized redirect URI
Replace the credential values in .env.

12. Provider User-Agent Overrides

Override the User-Agent header sent to each upstream provider. This is dynamically resolved at runtime by the executor base class:

process.env[`${PROVIDER_ID}_USER_AGENT`]

Source: open-sse/executors/base.ts → buildHeaders()

Variable	Default Value	When to Update
`CLAUDE_USER_AGENT`	`claude-cli/2.1.145 (external, cli)`	When Anthropic releases a new CLI version
`CODEX_USER_AGENT`	`codex-cli/0.132.0 (Windows 10.0.26200; x64)`	When OpenAI updates the Codex CLI
`CODEX_CLIENT_VERSION`	`0.131.0`	Override Codex client version independently of full UA string
`GITHUB_USER_AGENT`	`GitHubCopilotChat/0.45.1`	When GitHub Copilot Chat updates
`ANTIGRAVITY_USER_AGENT`	`antigravity/2.0.1 darwin/arm64`	When Antigravity IDE updates
`KIRO_USER_AGENT`	`AWS-SDK-JS/3.0.0 kiro-ide/1.0.0`	When Kiro IDE updates
`QODER_USER_AGENT`	`Qoder-Cli`	When Qoder CLI updates
`QWEN_USER_AGENT`	`QwenCode/0.15.11 (linux; x64)`	When Qwen Code updates
`CURSOR_USER_AGENT`	`connect-es/1.6.1`	When Cursor updates
`GEMINI_CLI_USER_AGENT`	`google-api-nodejs-client/10.3.0`	When Google API client updates

Tip

You can add User-Agent overrides for any provider using the pattern {PROVIDER_ID}_USER_AGENT. The executor dynamically constructs the env var name.

13. CLI Fingerprint Compatibility

When enabled, OmniRoute reorders HTTP headers and JSON body fields to match the exact signature of official CLI tools. This reduces the risk of account flagging while preserving your proxy IP.

Source: open-sse/config/cliFingerprints.ts, open-sse/executors/base.ts

Per-Provider

Variable	Effect
`CLI_COMPAT_CODEX=1`	Mimics Codex CLI request signature
`CLI_COMPAT_CLAUDE=1`	Mimics Claude Code request signature
`CLI_COMPAT_GITHUB=1`	Mimics GitHub Copilot request signature
`CLI_COMPAT_ANTIGRAVITY=1`	Mimics Antigravity request signature
`CLI_COMPAT_KIRO=1`	Mimics Kiro IDE request signature
`CLI_COMPAT_CURSOR=1`	Mimics Cursor request signature
`CLI_COMPAT_KIMI_CODING=1`	Mimics Kimi Coding request signature
`CLI_COMPAT_KILOCODE=1`	Mimics Kilo Code request signature
`CLI_COMPAT_CLINE=1`	Mimics Cline request signature
`CLI_COMPAT_QWEN=1`	Mimics Qwen Code request signature

Global

Variable	Effect
`CLI_COMPAT_ALL=1`	Enable fingerprint compatibility for all providers at once.

Note

This feature works alongside the User-Agent overrides (§12). The fingerprint system handles header ordering and body field ordering, while User-Agent overrides handle the specific UA string. Both can be enabled independently.

14. API Key Providers

API keys for providers that use direct authentication. Preferred setup: Dashboard → Providers → Add API Key.

Setting via environment variables is an alternative for Docker or headless deployments.

Recognized pattern: {PROVIDER_ID}_API_KEY

Variable	Provider
`DEEPSEEK_API_KEY`	DeepSeek
`GROQ_API_KEY`	Groq
`XAI_API_KEY`	xAI (Grok)
`MISTRAL_API_KEY`	Mistral AI
`PERPLEXITY_API_KEY`	Perplexity
`TOGETHER_API_KEY`	Together AI
`FIREWORKS_API_KEY`	Fireworks AI
`CEREBRAS_API_KEY`	Cerebras
`COHERE_API_KEY`	Cohere
`NVIDIA_API_KEY`	NVIDIA NIM
`NEBIUS_API_KEY`	Nebius (embeddings)

Tip

Keys set via the Dashboard are stored encrypted in SQLite and take precedence over environment variables.

15. Timeout Settings

All values are in milliseconds. Centralized resolution in src/shared/utils/runtimeTimeouts.ts.

Audit: Removed / Dead Variables

The following variables appeared in previous versions of .env.example but have no runtime references in the current codebase. They have been removed:

Variable	Reason
`STORAGE_DRIVER=sqlite`	Never read by any source file. SQLite is the only supported driver — no selection needed.
`INSTANCE_NAME=omniroute`	Present in old docs/env templates but unused at runtime. May return in a future multi-instance feature.
`SQLITE_MAX_SIZE_MB=2048`	Not referenced in source code. Database size is not artificially limited.
`SQLITE_CLEAN_LEGACY_FILES=true`	Not referenced in source code. Legacy cleanup was likely removed.
`CLI_ROO_BIN`	Not registered in `src/shared/services/cliRuntime.ts`.
`CLI_KIMI_CODING_BIN`	Not registered in `src/shared/services/cliRuntime.ts` (Kimi Coding uses OAuth, not a CLI binary).
`IFLOW_OAUTH_CLIENT_ID` / `IFLOW_OAUTH_CLIENT_SECRET`	Not referenced anywhere in source code.

Default Value Corrections

Variable	Old `.env.example` Value	Actual Code Default	Fixed
`APP_LOG_RETENTION_DAYS`	`90`	`7`	✅ Removed misleading value; documented `7` as default
`CALL_LOG_RETENTION_DAYS`	`90`	`7`	✅ Removed misleading value; documented `7` as default
