# Environment Variables Reference

> Complete reference for every environment variable recognized by OmniRoute.
> For a quick-start template, see [`.env.example`](../../.env.example).

> [!IMPORTANT]
> Every variable documented here must also appear in `.env.example`, and
> every variable in `.env.example` must appear here. `npm run check:env-doc-sync`
> enforces this on commit and in CI. To omit a variable on purpose, add it to
> the allowlist inside `scripts/check-env-doc-sync.mjs`.

## 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**              | `CHANGEME` | Bootstrap script                                   | Sets the initial admin dashboard password (matches `.env.example` default — kept obviously insecure to force a change). **Change before first use.** After login, change via Dashboard → Settings → Security.                                                                 |
| `OMNIROUTE_WS_BRIDGE_SECRET` | **Yes** (production) | _(unset)_  | `src/app/api/internal/codex-responses-ws/route.ts` | Shared secret for the internal Codex Responses WebSocket bridge. Authenticates bridge requests between the Electron/browser WS relay and OmniRoute. ⚠️ **REQUIRED in production — when unset, all WS bridge requests are rejected.** Generate with `openssl rand -base64 32`. |

### Generation Commands

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

> [!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/build/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.                                  |
| `OMNIROUTE_DB_HEALTHCHECK_INTERVAL_MS` | _(unset)_            | `src/lib/db/core.ts`                                  | Override the periodic SQLite healthcheck interval (ms). When unset, defaults are derived from `NODE_ENV`.                         |
| `OMNIROUTE_SKIP_DB_HEALTHCHECK`        | `0`                  | `src/lib/db/core.ts`, `src/lib/db/healthCheck.ts`     | Set to `1` to skip the DB healthcheck entirely on startup. Useful for short-lived tasks and integration tests.                    |
| `OMNIROUTE_FORCE_DB_HEALTHCHECK`       | `0`                  | `src/lib/db/core.ts`                                  | Set to `1` to force the DB healthcheck loop on, even when it would normally be skipped (e.g., short-lived tasks).                 |
| `OMNIROUTE_SKIP_POSTINSTALL`           | `0`                  | `scripts/postinstall.mjs`                             | Set to `1` to skip the native-runtime warm-up during `npm install`. Useful in CI/headless installs where sqlite is already built. |
| `OMNIROUTE_MIGRATIONS_DIR`             | _(auto-detect)_      | `src/lib/db/migrationRunner.ts`                       | Override the directory that the migration runner scans. Useful when shipping bundled migrations in custom builds.                 |
| `OMNIROUTE_SPEND_FLUSH_INTERVAL_MS`    | _(default in code)_  | `src/lib/spend/batchWriter.ts`                        | Flush interval (ms) for the batched spend/cost writer. Lower values reduce write coalescing; higher values reduce DB contention.  |
| `OMNIROUTE_SPEND_MAX_BUFFER_SIZE`      | _(default in code)_  | `src/lib/spend/batchWriter.ts`                        | Max buffered spend entries before a forced flush. Raise on high-QPS deployments; lower when bounded memory matters more.          |
| `BATCH_RETRY_DURATION_MS`              | `86400000` (24h)     | `open-sse/services/batchProcessor.ts`                 | Maximum retry window for individual batch items (ms). Items exceeding this duration are marked failed.                            |
| `BATCH_BACKOFF_BASE_MS`                | `5000`               | `open-sse/services/batchProcessor.ts`                 | Base delay (ms) for exponential backoff on batch item retries.                                                                    |
| `BATCH_BACKOFF_MAX_MS`                 | `3600000` (1h)       | `open-sse/services/batchProcessor.ts`                 | Cap (ms) for exponential backoff between batch item retries.                                                                      |

### 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.                |

## 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                                                                                           |

> [!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.

### Docker Example

```bash
# Mount host binaries into the container and tell OmniRoute where they are:
CLI_EXTRA_PATHS=/host-cli/bin
CLI_CONFIG_HOME=/root
CLI_ALLOW_CONFIG_WRITES=true
CLI_CLAUDE_BIN=/host-cli/bin/claude
```

### CLI Binary (`omniroute`) helpers

## 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/0.15.9 (linux; x64)`                | When Qwen Code updates                                        |
| `CURSOR_USER_AGENT`      | `Cursor/3.3`                                  | 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                 | Activation | 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_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         | Activation | Effect                                                          |
| ---------------- | ---------- | --------------------------------------------------------------- |
| `CLI_COMPAT_ALL` | `=1`       | Enable fingerprint compatibility for **all** providers at once. |

### Kimi Coding CLI identity overrides

| Variable                | Default              | Source File                              | Description                                                  |
| ----------------------- | -------------------- | ---------------------------------------- | ------------------------------------------------------------ |
| `KIMI_CLI_VERSION`      | `1.36.0`             | `src/lib/oauth/providers/kimi-coding.ts` | Override the Kimi CLI version sent during OAuth/API calls.   |
| `KIMI_CODING_DEVICE_ID` | _(captured default)_ | `src/lib/oauth/providers/kimi-coding.ts` | Override the captured Kimi device ID used in client headers. |

> [!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   |
| `NVIDIA_API_KEY`   | NVIDIA NIM |

> [!NOTE]
> Static `${PROVIDER}_API_KEY` entries for Groq, xAI, Mistral, Perplexity, Together AI, Fireworks, Cerebras, Cohere, Nebius, and Qianfan were removed in v3.8.0 because the runtime no longer reads them — those providers rely exclusively on Dashboard / `data/provider-credentials.json` / the encrypted DB. See the _Audit: Removed / Dead Variables_ section at the bottom of this document for the migration path.

> [!TIP]
> Keys set via the Dashboard are stored encrypted in SQLite and take precedence over environment variables.

`ENABLE_CC_COMPATIBLE_PROVIDER` is only for third-party relays that accept Claude Code clients
exclusively. OmniRoute rewrites requests so those relays accept them. If you only want to use
Claude Code CLI, or you are not sure what these relays are, keep this disabled and add a regular
Anthropic-compatible provider instead.

| `SKILLS_SANDBOX_NETWORK_ENABLED`  | `false`                                       | `src/lib/skills/builtins.ts` | Set `1`/`true` to allow outbound network from inside the sandbox. Defaults to **isolated** for safety.             |
| `SKILLS_ALLOWED_SANDBOX_IMAGES`   | _(empty)_                                     | `src/lib/skills/builtins.ts` | Comma-separated allowlist of container images permitted for sandbox execution. Empty means built-in default only.  |

> [!CAUTION]
> Enabling `SKILLS_SANDBOX_NETWORK_ENABLED=true` opens an egress path from arbitrary skill code. Pair with `OUTBOUND_SSRF_GUARD_ENABLED=true` and a strict `CORS_ORIGIN`/proxy policy in shared deployments.

### Docs translation pipeline

Used by `scripts/i18n/run-translation.mjs` (the `npm run i18n:run` command).
All five variables are unset by default — set them in `.env` only on machines
that should be able to run the docs translator.

| Variable                            | Default   | Source File                        | Description                                                               |
| ----------------------------------- | --------- | ---------------------------------- | ------------------------------------------------------------------------- |
| `OMNIROUTE_TRANSLATION_API_URL`     | _(unset)_ | `scripts/i18n/run-translation.mjs` | OpenAI-compatible base URL for the translation backend.                   |
| `OMNIROUTE_TRANSLATION_API_KEY`     | _(unset)_ | `scripts/i18n/run-translation.mjs` | Bearer token for the translation backend (never logged).                  |
| `OMNIROUTE_TRANSLATION_MODEL`       | _(unset)_ | `scripts/i18n/run-translation.mjs` | Model id, e.g. `gpt-4o-mini` or `cx/gpt-5.4-mini`.                        |

## 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                                                                                                                                             |

| `IFLOW_OAUTH_CLIENT_ID` / `IFLOW_OAUTH_CLIENT_SECRET`                                                                                                                           | Not referenced anywhere in source code.                                                                                                            |
| `CEREBRAS_API_KEY` / `COHERE_API_KEY` / `FIREWORKS_API_KEY` / `GROQ_API_KEY` / `MISTRAL_API_KEY` / `NEBIUS_API_KEY` / `PERPLEXITY_API_KEY` / `TOGETHER_API_KEY` / `XAI_API_KEY` | Removed in v3.8.0. The runtime no longer reads these env vars — credentials come from Dashboard / `data/provider-credentials.json` / encrypted DB. |
| `CURSOR_PROTOBUF_DEBUG`                                                                                                                                                         | Removed in v3.8.0. Cursor executor uses `CURSOR_DEBUG` / `CURSOR_STREAM_DEBUG` (see §22).                                                          |

Kiro is in `CLI_COMPAT_OMITTED_PROVIDER_IDS` — its toggle has no effect.                                                        |
| `QIANFAN_API_KEY`                                                                                                                                                               | Removed alongside other unused provider API key stubs in v3.8.0.                                                                                   |

### 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 |
