## 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

```bash
# 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.                                 |
| `CORS_ORIGIN`                 | `*`                   | Next.js middleware                       | CORS `Access-Control-Allow-Origin` value. Restrict for production.                                        |
| `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. |

## 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.

---

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 |
