First-run WebUI setup binds to `127.0.0.1` by default. Use manual configuration and a WebUI password before exposing the WebSocket channel beyond localhost.
`--dev` is a foreground source-checkout workflow and cannot be combined with `--background`.
It installs frontend dependencies when `webui/node_modules` is missing, proxies to the configured
WebSocket channel port, and stops Vite together with the foreground gateway.
## Gateway
`nanobot gateway` starts enabled chat channels, WebUI/WebSocket when configured, cron-backed system jobs, Dream, heartbeat, and the health endpoint. Most local browser users should start with `nanobot webui`; use `gateway` directly for service management, chat app operation, and advanced deployment. By default it runs in the foreground, which keeps existing scripts and terminal workflows unchanged. Use `--background` when you want a local macOS, Linux, or Windows process that you can manage from the CLI.

### Responses conversation state and compaction
Providers that use the Responses API can keep reasoning context across a
conversation, which helps with multi-step tasks. Supported providers can also
compact long conversations automatically.
nanobot preserves Responses conversation state automatically for OpenAI Responses, OpenAI Codex, Azure OpenAI, DeepSeek V4 Flash, and compatible GitHub Copilot models.
Native compaction is also automatic when the provider supports it. The
threshold is derived from the active model's context window and reserved output
headroom; no provider configuration is required.

### Cloudflare Tunnel + Cloudflare Access
For a local `cloudflared` process in front of nanobot, Cloudflare Access can
authenticate the user before forwarding the request and add
`Cf-Access-Jwt-Assertion`. Opt in to trusted-proxy no-token mode only when the
direct TCP peer is the tunnel process and the assertion is non-empty:
```json
{
"gateway": { "host": "127.0.0.1" },
"channels": {
"websocket": {
"host": "127.0.0.1",
"port": 8765,
"publicWsUrl": "wss://nanobot.example.com/",
"trustedProxyAuth": {
"trustedPeerCidrs": ["127.0.0.1/32", "::1/128"],
"assertionHeader": "Cf-Access-Jwt-Assertion"
}
}
}
}
```
This is two-part authorization: a trusted direct loopback peer **and** a
non-empty Cloudflare Access assertion. A trusted CIDR alone is not a bypass.
For this flow `/webui/bootstrap` returns connection metadata without a
bootstrap token or REST API token; the proxy assertion authorizes the WebSocket
handshake and REST requests directly.
Set `publicWsUrl` to the browser-facing `wss://` endpoint when the tunnel sends
the origin host header (such as `127.0.0.1:8765`); otherwise the WebUI could
attempt to open its WebSocket directly against the loopback address.
The assertion header must be generated
by Cloudflare Access after authentication; routing/client metadata headers such
as `Host`, `Forwarded`, `X-Forwarded-*`, `X-Real-IP`, and `CF-Connecting-IP`
are rejected as `assertionHeader` values. Nanobot trusts the assertion but does
not cryptographically validate the JWT, so configure the tunnel and Access
policy carefully and do not expose the nanobot listener directly to untrusted
clients. Forwarded client headers do not establish proxy trust.

### ModelScope
ModelScope (魔搭社区) exposes an OpenAI-compatible LLM endpoint plus a separate async image generation API. Both are covered by the built-in `modelscope` provider.
Create a ModelScope [access token](https://modelscope.cn/my/myaccesstoken), then choose a model whose page exposes API-Inference. The example below uses [`Qwen/Qwen3-32B`](https://modelscope.cn/models/Qwen/Qwen3-32B); hosted availability and quotas are controlled by ModelScope. See the official [API-Inference guide](https://modelscope.cn/docs/model-service/API-Inference/intro) for current service details.

"maxTokens": 8192,

}
},
"agents": {
"defaults": {

}
}
}
```
Use an inference-enabled model ID exactly as ModelScope publishes it (usually `Namespace/model-name`). The default base URL is `https://api-inference.modelscope.cn/v1`; override `providers.modelscope.apiBase` only if your account routes through a different host. Chat model IDs may optionally be prefixed with `modelscope/`; nanobot strips that routing prefix before sending the request.
ModelScope image generation reuses the same provider key but is configured under `tools.imageGeneration`, not in a model preset:
```json
{
"tools": {
"imageGeneration": {
"enabled": true,
"provider": "modelscope",
"model": "Qwen/Qwen-Image-2512"
}
}
}
```
Use the image model's exact ModelScope ID without a leading `modelscope/`; the image client sends this value unchanged and handles ModelScope's async submit/poll flow. The example uses [`Qwen/Qwen-Image-2512`](https://modelscope.cn/models/Qwen/Qwen-Image-2512). See [Image Generation](./image-generation.md#modelscope) for supported sizes, aspect ratios, and the complete provider configuration.

3. Client opens WebSocket with `?token=nbwt_aBcDeFg...&client_id=...`.
4. The token is consumed (single use) and cannot be reused.
The embedded WebUI's `/webui/bootstrap` route returns a WebSocket token and
REST `api_token` for local or secret-authenticated requests. When
`trustedProxyAuth` authenticates the direct proxy peer, it returns connection
metadata only: no bootstrap token, no REST API token, and no token query
parameter is required for the WebSocket handshake or subsequent REST requests.
### Trusted proxy no-token bootstrap
`trustedProxyAuth` is an opt-in alternative for deployments where an
identity-aware reverse proxy authenticates the user before connecting to nanobot.
The proxy assertion becomes the authentication boundary for the entire WebUI
surface: `/webui/bootstrap`, the WebSocket handshake, and REST API routes.
Bootstrap is accepted only when **both** the direct TCP peer matches one of
`trustedPeerCidrs` and the configured assertion header is present and non-empty.
A trusted address by itself is never sufficient.
Nanobot deliberately uses only `connection.remote_address` for the peer check.
It never uses `X-Forwarded-For`, `Forwarded`, `X-Real-IP`, `CF-Connecting-IP`,
or `X-Forwarded-Host` to decide whether the proxy is trusted. Nanobot trusts the
assertion supplied by the explicitly trusted peer, but does not cryptographically
validate or interpret the JWT/assertion contents. Do not enable this option if
untrusted clients can connect directly to the nanobot listener.
The configured assertion header must be a proxy-generated authentication
assertion, not a routing or client metadata header. Headers such as `Host`,
`Forwarded`, `X-Forwarded-*`, `X-Real-IP`, and `CF-Connecting-IP` are rejected
by configuration; use the identity provider's post-authentication assertion
header instead (for example, `Cf-Access-Jwt-Assertion`).
For example, a local Cloudflare Tunnel with Cloudflare Access can validate the
user at the edge and forward the resulting `Cf-Access-Jwt-Assertion`:
```json
{
"channels": {
"websocket": {
"host": "127.0.0.1",
"publicWsUrl": "wss://nanobot.example.com/",
"trustedProxyAuth": {
"trustedPeerCidrs": ["127.0.0.1/32", "::1/128"],
"assertionHeader": "Cf-Access-Jwt-Assertion"
}
}
}
}
```
This works only when the directly connected `cloudflared` process reaches
nanobot over the configured loopback address and supplies a non-empty assertion.
Keep nanobot firewalled from untrusted clients; this configuration is not a
CIDR-based bootstrap bypass.
The embedded WebUI's `/webui/bootstrap` route also returns a WebSocket token.
It returns a separate `api_token` for REST routes to same-machine localhost
browser requests, or after the request proves knowledge of `tokenIssueSecret`
or the static `token`.
