**Visual editor for your codebase.**

Airship puts an infinite design canvas in front of your dev server. Select an element, describe the change, and watch Claude Code, Codex or OpenCode update the source — without rebuilding your UI in a separate design tool.

```
npx @airshiplabs/cli --target 3000
```

No plugin. No config. Nothing added to your dependencies or your bundle.

[airship.design](https://airship.design) · [CLI reference](#cli-reference) · [Configuration](#configuration) · [Questions](#questions)

**1. Start your app the way you always do.**

```
pnpm dev    # http://localhost:3000
```

Works with Vite, Next, Remix, Rails, or anything that serves HTML over HTTP. No plugins required.

**2. Point Airship at your dev server.**

```
npx @airshiplabs/cli --target 3000
```

Airship connects to the port you're already running and opens the visual editor on the next
free port. Or install it once and use the `airship`

binary:

```
npm i -g @airshiplabs/cli
airship --target 3000
```

**3. Bring your coding agent.**

```
airship --target 3000 --agent codex --safe
```

Pick the agent you already use and start making changes without running a separate agent interface.

Airship uses the authentication you already have configured for Claude Code, Codex, or
OpenCode. Run `airship doctor`

if something does not work.

`--exec`

starts your dev server and stops it again when Airship exits. Leave `--target`

off and
it reads the port from your `package.json`

:

```
airship --exec "pnpm dev"
```

Run `airship`

on its own and it just asks you for the port, the agent and the mode.

A CLI, and nothing else.

**Nothing goes into your project.** Airship runs in front of the dev server you already have. Your build, your config and your dependencies are untouched.**Every frame is a real browser window.** A phone frame behaves like a phone, however far you zoom out. Mobile and desktop sit side by side — both live, both editable, one source file.**Changes land in your code.** Click an element and Airship knows the file and line that drew it. Describe the change, get the diff, undo it if you don't like it.**Nothing leaves your machine.** No account, no telemetry, no service to sign up for.

Two ways to look at your app. Same editor either way.

** canvas** (default) — your app on a pannable canvas, one live frame per device size.

** inline** — the editor on top of your own page, one window.

Pick one at launch with `airship --mode inline`

, or switch any time from the bottom bar. Your
choice sticks across reloads and as you click around your app. Add `?__airship=inline`

to a URL
to try the other one once, without changing your preference; `?__airship=shell`

is the way back
to the canvas — the parameter takes the internal mode name, so it is `shell`

, not `canvas`

.

Open any route of your app in Airship — `/pricing`

, `/settings`

— and every frame opens there.

On the canvas:

| Gesture | |
|---|---|
| wheel / two-finger | pan |
| ⌘/ctrl-wheel, pinch | zoom at cursor |
| space-drag, middle-drag | pan |
| ⇧1 / ⇧2 / ⇧0 | fit / zoom to selection / 100% |

Click an element and it fills the inspector. Every tab is looking at the same thing.

`Edit`

is position, size, spacing and layout — the shot up in [Quick start](#quick-start). `CSS`

is the box model, the rules that are actually hitting the element, and your own tweaks on top:

`DOM`

is the tree. Click a node to select it, or drag one to move it somewhere else:

Pick one with `--agent`

, or switch between them as you go. They are not equal, and Airship tells
you what you're giving up at startup.

`claude` (default) |
`codex` |
`opencode` |
|
|---|---|---|---|
| Watch it write | word by word | the whole reply at once, at the end | word by word |
| Pick up an old chat | yes | yes | yes |
| Branch off a chat | yes | starts fresh, and says so | yes, history kept |
| Shows what it cost | in dollars | tokens only | in dollars |
`--effort` |
yes | yes | ignored |
`--max-turns` , `--max-budget` |
yes | ignored |
ignored |
`--model` |
a model name | a model name | needs the `provider/model` form |
`--safe` |
checks each edit and command | real sandbox |
asks before each edit and command |
| Install | included | included | you install it yourself |

Undo is Airship's, not the agent's. It keeps the previous version of every file it touches, so
undo works on all three. One catch: `codex`

and `opencode`

get that previous version from Git,
so **undo needs your project to be a Git repo on those two**. Airship warns you at startup.

Airship reuses whatever the chosen agent already has, and warns at startup if it finds nothing.

| Agent | Needs one of |
|---|---|
`claude` |
`ANTHROPIC_API_KEY` , `CLAUDE_CODE_OAUTH_TOKEN` , or a `claude` login (`~/.claude` ) |
`codex` |
`CODEX_API_KEY` , `OPENAI_API_KEY` , or a `codex login` (`~/.codex/auth.json` ) |
`opencode` |
the `opencode` binary on PATH, plus a provider key or an `opencode auth login` |

OpenCode is a separate install — `brew install sst/tap/opencode`

or `npm i -g opencode-ai`

—
and accepts `ANTHROPIC_API_KEY`

, `OPENAI_API_KEY`

, `OPENCODE_API_KEY`

, `OPENROUTER_API_KEY`

,
`GEMINI_API_KEY`

, `GOOGLE_GENERATIVE_AI_API_KEY`

, `AWS_BEARER_TOKEN_BEDROCK`

or
`AWS_ACCESS_KEY_ID`

.

**By default the agent runs unsandboxed.** It can write anywhere you can and reach the network —
the same access it has when you run it from your terminal. Pass `--safe`

to confine it:

| default | `--safe` |
|
|---|---|---|
`codex` |
full access, network on | locked to your project folder, no network, no web search |
`claude` |
full access, no sandbox | edits kept inside your project, dangerous commands blocked |
`opencode` |
full access | asks before every edit and command, checked the same way; no web fetch, no web search, nothing outside your project |

`--safe`

is not equally strong on all three, and the CLI says so at launch:

**Only** The operating system stops it writing outside your project. On`codex`

gets a real sandbox.`claude`

and`opencode`

, Airship checks each edit and command first — a good check, but a check, not a wall.**That check looks for known-dangerous commands; it does not understand shell.** It catches`rm -rf`

. It does not catch a write pointed somewhere else, like`echo x > /elsewhere`

.Airship switches off their web tools, but nothing stops a command they run from opening a connection anyway. Only a sandbox can.`claude`

and`opencode`

can still reach the network.

If a hard guarantee matters more to you than which agent you use, run
`airship --agent codex --safe`

.

Diffs and undo work the same either way — `--safe`

has no effect on them.

```
airship [options]
airship --target <port> [options]
airship <command> [options]
```

| Command | |
|---|---|
`airship` |
Launch the visual editor against your dev server. Bare at a terminal, it asks first. |
`airship init` |
Create an `airship.config.json` for this project. |
`airship doctor` |
Check your environment and report what is wrong. |

Flags accept `--flag value`

and `--flag=value`

, a camelCase spelling of any kebab name
(`--maxTurns`

≡ `--max-turns`

), and `--no-<name>`

to turn any boolean off. A bare `--`

stops flag
parsing — airship takes no positional arguments, so anything after it is ignored rather than
forwarded.

| Flag | Default | |
|---|---|---|
`-t, --target <port>` |
Port your dev server is already running on. Detected from your `package.json` when omitted. |
|
`-p, --port <port>` |
Port for the airship proxy. | `target + 1` |
`--cwd <dir>` |
Project root for edits. | current directory |
`--mode <name>` |
Editor mode: `canvas` or `inline` . Switchable from the editor too. |
`canvas` |
`--exec <command>` |
Start your dev server with this command and stop it when airship exits. | |
`--open` |
Open the editor in your browser once it is listening. |

| Flag | Default | |
|---|---|---|
`-a, --agent <name>` |
Coding agent: `claude` , `codex` , `opencode` . |
`claude` |
`-m, --model <id>` |
Model id. | the agent's own default |
`--effort <level>` |
Reasoning effort: `minimal` , `low` , `medium` , `high` , `xhigh` , `max` . |
|
`--max-turns <n>` |
Cap agent turns per edit (claude only). | `24` |
`--max-budget <usd>` |
Stop an edit if it exceeds this cost in USD (claude only). | |
`--commit` |
Auto-commit each accepted edit (Conventional Commits). |

`-m`

is `--model`

, not `--mode`

. `--mode`

has no short alias.

| Flag | Default | |
|---|---|---|
`--safe` |
Confine edits to the project directory and cut network access. See
|

| Flag | Default | |
|---|---|---|
`--codex-path <path>` |
Path to the `codex` binary. |
bundled |
`--codex-config <k=v>` |
Extra `codex --config` pair; repeatable. |
|
`--opencode-path <path>` |
Path to the `opencode` binary. |
found on PATH |
`--opencode-url <url>` |
Attach to a running `opencode serve` instead of starting one. |
|
`--opencode-agent <name>` |
Run as a named opencode agent. | its own |
`--opencode-config <file>` |
JSON file merged into the opencode server config. |

`--codex-config`

reads the shape of the value: `true`

/`false`

become TOML booleans and anything
numeric becomes a number, so `--codex-config network_access=true`

sends a boolean, not the string.
Quote it — `--codex-config k='"true"'`

— to keep a string a string.

| Flag | |
|---|---|
`--json` |
Machine-readable JSON on stdout, no colour and no banner. |
`-q, --quiet` |
Suppress the launch banner. Warnings still print. |
`--debug` |
Print stack traces on failure. |
`-h, --help` |
Show this help. |
`-v, --version` |
Print the version. |

Banners, warnings and errors go to stderr; `--json`

payloads, help and `--version`

go to stdout,
so `airship --json | jq`

is reliable.

Writes an `airship.config.json`

from the same questions the bare `airship`

wizard asks, so it
stops asking. Takes `--cwd`

and the global flags. Needs a terminal.

Checks, in order: `node`

, `airship`

, `config`

, `git repo`

, `overlay bundle`

, `agent claude`

,
`agent codex`

, `agent opencode`

, `dev server`

. Each reports `ok`

, `warn`

or `fail`

with a hint.
Only your preferred agent (`--agent`

, default `claude`

) can fail the run; the other two warn.

Exits `1`

if any check failed, so `airship doctor && airship`

works. Takes `--cwd`

, `--target`

,
`--agent`

and the global flags.

| Code | |
|---|---|
`0` |
Fine. |
`1` |
Something failed. |
`2` |
Bad flag, bad value, or a terminal was needed and there wasn't one. |
`127` |
Not an airship command. |
`130` |
Interrupted — Ctrl-C, or a cancelled prompt. |

Settings resolve in this order, highest first:

```
flags  →  AIRSHIP_* environment  →  airship.config.json  →  defaults
```

`airship.config.json`

, or an `"airship"`

key in your `package.json`

. Run `airship init`

to write
one. Every key is a flag name, in either kebab or camel case:

```
{
  "agent": "claude",
  "mode": "canvas",
  "target": 3000,
  "safe": true
}
```

Airship looks for it from `--cwd`

upwards and **stops at your repository root**, so a stray
config file somewhere above your repo won't affect you. Misspell a key and it says so, with a
suggestion — it never quietly ignores one.

Every flag except `--help`

and `--version`

has an environment variable: `AIRSHIP_`

plus the flag
name uppercased, with `-`

as `_`

.

```
AIRSHIP_TARGET          AIRSHIP_AGENT           AIRSHIP_CODEX_PATH
AIRSHIP_PORT            AIRSHIP_MODEL           AIRSHIP_CODEX_CONFIG
AIRSHIP_CWD             AIRSHIP_EFFORT          AIRSHIP_OPENCODE_PATH
AIRSHIP_MODE            AIRSHIP_MAX_TURNS       AIRSHIP_OPENCODE_URL
AIRSHIP_EXEC            AIRSHIP_MAX_BUDGET      AIRSHIP_OPENCODE_AGENT
AIRSHIP_OPEN            AIRSHIP_COMMIT          AIRSHIP_OPENCODE_CONFIG
AIRSHIP_SAFE            AIRSHIP_JSON            AIRSHIP_QUIET
AIRSHIP_DEBUG
```

`AIRSHIP_HELP`

and `AIRSHIP_VERSION`

are deliberately not read — exporting one would leave the
CLI unable to run anything. Booleans take `1`

/`true`

/`yes`

/`on`

or `0`

/`false`

/`no`

/`off`

;
anything else is an error rather than a guess.

Three more are honoured: `AIRSHIP_EDITOR`

(`vscode`

, `cursor`

, `windsurf`

or `zed`

— which
editor "open in editor" prefers, otherwise probed in that order), and `NO_COLOR`

/ `FORCE_COLOR`

.

`--cwd`

is the folder your dev server treats as its root, which is not always your repository
root. Airship needs it to turn the paths your dev server reports (`/src/app.tsx`

) into real
files on disk. In a monorepo where the app lives in `apps/web`

, that's `--cwd apps/web`

.

Leave `--target`

off and Airship works it out, trying each likely port in turn and taking the
first one that answers:

-
**The port in your dev script**— a`--port`

,`-p`

or`PORT=`

in`scripts.dev`

,`scripts.start`

or`scripts.serve`

. -
**Your framework's default**, by what is in your dependencies:Dependency Port `next`

,`nuxt`

,`@remix-run/dev`

,`react-scripts`

`3000`

`parcel`

`1234`

`@angular/cli`

`4200`

`astro`

`4321`

`@sveltejs/kit`

,`vite`

`5173`

`storybook`

(or any`@storybook/*`

)`6006`

`gatsby`

`8000`

`@11ty/eleventy`

`8080`

Most specific first — a project with both

`vite`

and`storybook`

is a Vite app that also has a component catalogue, not the other way round. -
**Common ports**—`3000`

,`5173`

,`8080`

,`4321`

,`4200`

.

With `--exec`

it's the opposite: the port has to be *free*, since Airship is about to start your
dev server on it. It won't start one on a port that's already taken.

Including the ones with unflattering answers.

**Do I need a plugin, or to change my build?**
No. Airship runs as a reverse proxy in front of your existing dev server. Nothing is added to
your dependencies, config, or bundle.

**Does it work with Tailwind, CSS Modules or styled-components?**
Yes. Airship works with the styling system already in your project. It works with the tokens and
styling conventions already in your codebase, so visual changes can map back to the values your
design system already uses.

**How does it know which file an element came from?**
Dev builds already record where each thing on screen came from. Airship reads that to find the
file and line, and hands it to the agent.

**What exactly gets sent to the agent?**
What you clicked, the file and line it came from, anything you changed in the inspector, the
frames you were working in — and whatever you typed.

**Can I use my existing coding agent?**
Yes. Airship works with Claude Code, Codex, and OpenCode, so you don't need to change your agent
just to use the visual editor.

**Is it safe to point at a real repository?**
Airship runs locally and works directly on the repository you point it at. By default your
coding agent has the same access to your files and the network that it always has. `--safe`

can
keep edits inside your project and block dangerous commands — read [Safety](#safety) for what it
does and doesn't cover on each agent.

**How do I undo something?**
Every edit can be undone from Airship, which keeps the previous version of the file. On `claude`

that's all there is to it. On `codex`

and `opencode`

that previous version comes from Git, so
those two need your project to be a repository. See [Agents](#agents).

**Can I see how a change affects different devices?**
Yes. Airship runs the same app at several real device sizes at once. Make a change once and
watch it land on desktop, tablet and mobile together, without resizing anything.

**Can I use Airship without Git?**
Yes, Airship doesn't require it. But undo on `codex`

and `opencode`

works by asking Git for the
previous version of the file, so without a repository you lose undo on those two. `claude`

is
unaffected. See [Agents](#agents).

**Does my code leave my machine?**
Airship runs entirely on localhost. It has no account, telemetry, or hosted service, and your
code isn't sent to Airship. Your chosen coding agent handles requests using the same credentials
and provider it would use from your terminal.

Node 22.13 or later, and one of Claude Code, OpenAI Codex or OpenCode.
