# 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`. |
| `OMNIROUTE_PEER_STAMP_TOKEN` | No (auto)            | _(auto per boot)_ | `src/server/authz/policies/management.ts` | Per-process secret proving the trusted peer-IP stamp came from OmniRoute's own HTTP server (`scripts/dev/peer-stamp.mjs`). The authz middleware trusts request locality (loopback/LAN gating of LOCAL_ONLY routes) only when the stamp carries this token. Auto-generated each boot — leave unset; only pin it for multi-process setups that must share the stamp. |

### 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.          |
| `OMNIROUTE_PROXY_FETCH_DEBUG`          | _(unset)_            | `open-sse/utils/proxyFetch.ts`                        | Set to `"true"` to emit `[ProxyFetch]` debug logs on the Vercel relay path. Off by default to avoid leaking routing hints.        |
| `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.                                                                      |
| `BATCH_MAX_CONCURRENT`                 | `1`                  | `open-sse/services/batchProcessor.ts`                 | Maximum number of batches processed concurrently. Raise to increase throughput; keep low to avoid rate-limit storms.              |

### 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                                                                                                                                                    |

## 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_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. |

> [!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.

## 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                     |
| `CLAUDE_DISABLE_TOOL_NAME_CLOAK` | `false` | `executors/base.ts` + `executors/cliproxyapi.ts` | Set to `1`/`true` to forward third-party harness tool names verbatim to Anthropic on both Anthropic-bound paths (native OAuth and CLIProxyAPI). By default the executor deterministically aliases non-Claude-Code tool names (Claude Code canonical mapping where one exists, otherwise PascalCase) and reverses them on the response via `_toolNameMap`, so harnesses with snake_case tools are not refused as fingerprinted third-party clients. Debugging only. |
| `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                                         |
| `KIRO_OAUTH_CLIENT_ID`   | `kiro-cli`                                    | Override the Kiro social device-code `clientId` (public id)   |
| `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.

## 15. Timeout Settings

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

Combo target attempts inherit the resolved upstream request timeout (`FETCH_TIMEOUT_MS`, or
`REQUEST_TIMEOUT_MS` when it supplies the fetch default). Set `targetTimeoutMs` in a combo,
combo defaults, or provider override only to make combo fallback faster; values above the
current upstream timeout are capped to the upstream timeout.

### Circuit Breaker Thresholds

Provider-level circuit breaker tuning. Defaults reflect the scaled values used since v3.6 for 500+ connections.

| Variable                                      | Default | Source File                    | Description                                                                 |

| `OMNIROUTE_CIRCUIT_BREAKER_LOCAL_THRESHOLD`   | `2`     | `open-sse/config/constants.ts` | Consecutive failure threshold for local providers (Ollama, LM Studio, ...). |
| `OMNIROUTE_CIRCUIT_BREAKER_LOCAL_RESET_MS`    | `15000` | `open-sse/config/constants.ts` | Reset window (ms) for local provider breaker.                               |

### Scenarios

| Scenario                         | Configuration                                          |

## 16. Logging

The logging system writes to both stdout and rotated log files. All configuration is read by `src/lib/logEnv.ts`.

| Variable                                  | Default                    | Description                                                                       |

`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.

## 24. Skills Sandbox (v3.8.0+)

Limits and safety knobs applied when the Skills framework (`src/lib/skills/`) executes user-defined automations in a sandboxed environment.

| `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.

## 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:

### 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 |

### OpenCode config regeneration (ad-hoc tooling)

Used by `scripts/ad-hoc/regen-opencode-config.ts` to regenerate an `opencode.json`
with accurate `limit.context` and `limit.output` values pulled from the running
OmniRoute instance. None of these are required for normal operation — the script
is developer tooling only.

| Variable            | Default                   | Source File                              | Description                                                                                                            |
| ------------------- | ------------------------- | ---------------------------------------- | ---------------------------------------------------------------------------------------------------------------------- |
| `OMNIROUTE_URL`     | `http://localhost:20128`  | `scripts/ad-hoc/regen-opencode-config.ts` | Base URL of the OmniRoute instance to query for `/v1/models`.                                                          |
| `OMNIROUTE_KEY`     | _(unset)_                 | `scripts/ad-hoc/regen-opencode-config.ts` | API key to authenticate against the OmniRoute `/v1/models` endpoint. Falls back to `OPENCODE_API_KEY` when unset.        |
| `OPENCODE_API_KEY`  | _(unset)_                 | `scripts/ad-hoc/regen-opencode-config.ts` | OpenCode-style API key (`sk-...`) written into the regenerated `opencode.json`. Falls back to `OMNIROUTE_KEY` when unset. |
