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.

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

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.

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)	—

Warning

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

1. Go to Google Cloud Console → Credentials
2. Create an OAuth 2.0 Client ID (type: "Web application")
3. Add your server URL as Authorized redirect URI
4. 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/1.0.83 (external, cli)	When Anthropic releases a new CLI version
CODEX_USER_AGENT	codex-cli/0.92.0 (Windows 10.0.26100; x64)	When OpenAI updates the Codex CLI
CODEX_CLIENT_VERSION	0.92.0	Override Codex client version independently of full UA string
GITHUB_USER_AGENT	GitHubCopilotChat/0.26.7	When GitHub Copilot Chat updates
ANTIGRAVITY_USER_AGENT	antigravity/1.104.0 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/0.12.3 (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/9.15.1	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.

---

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
