Notte Browser

Notte Browser CLI Skill

Command-line interface for launching and controlling Notte cloud browser sessions, scraping pages, managing browser credentials, and deploying reusable browser workflows as Notte Functions. A Function is the deployment form of a tested browser task: it can be invoked later as an HTTP API endpoint, run from the CLI/SDK, or scheduled.

General Documentation

For broader Notte concepts, current docs, and internet-search entry points, start with the documentation index:

https://docs.notte.cc/llms.txt

Setup

Use this skill after the notte CLI is installed. If authentication is missing, run the interactive CLI login flow and wait for it to complete.

# Install with Homebrew
brew tap nottelabs/notte-cli https://github.com/nottelabs/notte-cli.git
brew install notte

# Or install with Go
go install github.com/nottelabs/notte-cli/cmd/notte@latest

# Authenticate locally, or set NOTTE_API_KEY for CI/non-interactive agents
notte auth login
# export NOTTE_API_KEY=...
notte auth status

Authentication Handling

Missing authentication is an interactive setup step, not a blocker and not a reason to switch to SDK code.

If notte auth status reports that authentication is missing, you MUST run:

notte auth login

Tell the user to complete the browser login flow. Then poll authentication status every 5 seconds for up to 5 minutes:

notte auth status

Do not write SDK code, switch to SDK docs, or build a fallback script because auth is missing. SDK code uses the same Notte authentication and does not solve this problem. Continue only after CLI authentication succeeds, or ask the user for help if login does not complete after 5 minutes.

Quick Start

# 1. Authenticate. If this opens a browser login, wait for the user to finish.
notte auth login
notte auth status

# 2. Start a browser session
notte sessions start

# 3. Goto and observe
notte page goto "https://example.com"
notte page observe
notte page screenshot

# 4. Execute actions (use IDs from observe, or Playwright selectors)
notte page click "B3"
notte page fill "I1" "hello world"
# If observe IDs don't work, use Playwright selectors:
# notte page click "button:has-text('Submit')"

# 5. Scrape content
notte page scrape --instructions "Extract all product names and prices"

# 6. Stop the session
notte sessions stop

Command Categories

Session Management

Control browser session lifecycle:

# Start a new session
notte sessions start [flags]
  --headless                 Run in headless mode (default: true)
  --idle-timeout-minutes     Idle timeout in minutes
  --max-duration-minutes     Maximum session lifetime in minutes
  --proxy                    Use default proxies
  --proxy-country      Proxy country code (e.g. us, gb, fr)
  --solve-captchas           Automatically solve captchas
  --profile-id   Load browser state from a profile
  --profile-persist          Save browser state back to the profile on session close
  --viewport-width           Viewport width in pixels
  --viewport-height          Viewport height in pixels
  --user-agent               Custom user agent string
  --cdp-url                  CDP URL of remote session provider
  --use-file-storage         Enable file storage for the session

# Get current session status
notte sessions status

# Stop current session
notte sessions stop

# List sessions (with optional pagination and filters)
notte sessions list [--page N] [--page-size N] [--only-active]

Note: When you start a session, it automatically becomes the "current" session (i.e NOTTESESSIONID environment variable is set). All subsequent commands use this session by default. Use --session-id only when you need to manage multiple sessions simultaneously or reference a specific session.

Browser profiles: Profiles store browser state such as cookies, localStorage, and sessionStorage. Start a session with --profile-id to load that saved state; add --profile-persist when starting the session if changes should be saved back to the profile when the session closes.

Session debugging:

# Get network logs
notte sessions network

# Get replay URL/data
notte sessions replay

Session export:

# Export session steps as Python workflow code.
# Use --session-id to export a specific session, including one that has been stopped.
notte sessions workflow-code --session-id 

# example flow
notte sessions start
notte page goto news.ycombinator.com
notte page scrape --instructions "Extract the top 10 stories from Hacker News. For each story return: rank, title, URL, points, author, number of comments" -o json
notte sessions workflow-code

# returns
from __future__ import annotations

from notte_sdk import NotteClient
from pydantic import BaseModel

class Story(BaseModel):
    rank: int | None = None
    title: str | None = None
    url: str | None = None
    points: int | None = None
    author: str | None = None
    number_of_comments: int | None = None

class Model(BaseModel):
    stories: list[Story] | None = None

client = NotteClient()

def run() -> Model:
    with client.Session(use_file_storage=True) as session:
        _ = session.execute(type='goto', url='news.ycombinator.com')

        # directly parses the output using response_format and returns the Model
        return session.scrape(instructions='Extract the top 10 stories from Hacker News. For each story return: rank, title, URL, points, author, number of comments', only_main_content=False, only_images=False, scrape_links=True, scrape_images=False, response_format=Model)

run()

Cookie management:

# Get all cookies
notte sessions cookies

# Set cookies from JSON file
notte sessions cookies-set --file cookies.json

Page Actions

Simplified commands for page interactions:

Element Interactions:

# Click an element (use either the IDs from observe, or a selector)
notte page click "B3"
notte page click "#submit-button"
  --timeout     Timeout in milliseconds
  --enter       Press Enter after clicking

# Fill an input field
notte page fill "I1" "hello world"
  --clear       Clear field before filling
  --enter       Press Enter after filling

# Check/uncheck a checkbox
notte page check "#my-checkbox"
  --value       true to check, false to uncheck (default: true)

# Select dropdown option
notte page select "#dropdown-element" "Option 1"

# Download file by clicking element
notte page download "L5"

# Upload file to input
notte page upload "#file-input" --file /path/to/file

# Run JavaScript in the Page
- Escape single quotes if needed.
- Don’t use logging (output won’t be captured).
- Use a single statement or a function that returns a value.

# Single expression
notte page eval-js 'document.title'

# Function with return value
notte page eval-js '
() => {
  const els = document.querySelectorAll("a");
  return els.length;
}
'

Navigation:

notte page goto "https://example.com"
notte page new-tab "https://example.com"
notte page back
notte page forward
notte page reload

Scrolling:

notte page scroll-down [amount]
notte page scroll-up [amount]

Keyboard:

notte page press "Enter"
notte page press "Escape"
notte page press "Tab"

Tab Management:

notte page switch-tab 1
notte page close-tab

Page State:

# Observe page state and available actions
notte page observe

# Save a screenshot in tmp folder
notte page screenshot

# Scrape content with instructions
notte page scrape --instructions "Extract all links" [--only-main-content]

--only-main-content can reduce output size and token cost by filtering out navigation, sidebars, footers, and other page chrome. It can also reduce recall, especially on dynamic pages or layouts where important content is not classified as main content. When completeness matters, try scraping without --only-main-content first, then add it only if the full-page output is too noisy or expensive.

Utilities:

# Wait for specified duration
notte page wait 1000

# Solve CAPTCHA
notte page captcha-solve "recaptcha"

# Mark task complete
notte page complete "Task finished successfully" [--success=true]

# Fill form with JSON data
notte page form-fill --data '{"email": "test@example.com", "name": "John"}'

AI Agents

Start and manage AI-powered browser agents:

# List all agents (with optional pagination and filters)
notte agents list [--page N] [--page-size N] [--only-active] [--only-saved]

# Start a new agent (auto-uses current session if active)
notte agents start --task "Navigate to example.com and extract the main heading"
  --session-id             Session ID (uses current session if not specified)
  --vault-id               Vault ID for credential access
  --persona-id             Persona ID for identity
  --max-steps              Maximum steps for the agent (default: 30)
  --reasoning-model        Custom reasoning model

# Get current agent status
notte agents status

# Stop current agent
notte agents stop

# Export agent steps as workflow code
notte agents workflow-code

# Get agent execution replay
notte agents replay

Note: When you start an agent, it automatically becomes the "current" agent (saved to ~/.notte/cli/current_agent). All subsequent commands use this agent by default. Use --agent-id only when you need to manage multiple agents simultaneously or reference a specific agent.

Agent ID Resolution:

1. --agent-id flag (highest priority)
2. NOTTE_AGENT_ID environment variable
3. ~/.notte/cli/current_agent file (lowest priority)

Functions (Workflow Automation and API Endpoints)

Use Notte Functions to create callable, scheduled, or reusable browser automations. This is the path for turning a browser task or scrape into an endpoint, API, webhook, job, workflow, or service.

A Notte Function is the deployed endpoint form of a browser workflow: run(...) parameters become invocation variables, and its returned JSON-serializable value becomes the run result.

# List all functions (with optional pagination and filters)
notte functions list [--page N] [--page-size N] [--only-active]

# Create a function from a workflow file
notte functions create --file workflow.py [--name "My Function"] [--description "..."] [--shared]

# Show current function details
notte functions show

# Update current function code
notte functions update --file workflow.py

# Delete current function
notte functions delete

# Run current function
notte functions run

# Invoke the deployed Function over HTTP from another service
curl -L -X POST "https://api.notte.cc/functions/{function_id}/runs/start" \
  -H "Authorization: Bearer $NOTTE_API_KEY" \
  -H "X-Notte-Api-Key: $NOTTE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "function_id": "{function_id}",
    "variables": {
      "url": "https://example.com",
      "max_items": 10
    }
  }'

# List runs for current function (with optional pagination and filters)
notte functions runs [--page N] [--page-size N] [--only-active]

# Stop a running function execution
notte functions run-stop --run-id 

# Get run logs and results
notte functions run-metadata --run-id 

# Schedule current function with cron expression
notte functions schedule --cron "0 9 * * *"

# Remove schedule from current function
notte functions unschedule

# Fork a shared function to your account
notte functions fork --function-id 

Note: When you create a function, it automatically becomes the "current" function. All subsequent commands use this function by default. Use --function-id only when you need to manage multiple functions simultaneously or reference a specific function (like when forking a shared function).

For reusable or repeated browser work, load and follow [Function Management Reference](references/function-management.md) before creating or updating a Function. Load [Python SDK Interop](references/python-sdk-interop.md) only when editing exported workflow code or writing Function files by hand.

Account Management

Personas - Auto-generated identities with email:

# List personas (with optional pagination and filters)
notte personas list [--page N] [--page-size N] [--only-active]

# Create a persona
notte personas create [--create-vault]

# Show persona details
notte personas show --persona-id 

# Delete a persona
notte personas delete --persona-id 

# List emails received by persona
notte personas emails --persona-id 

# List SMS messages received
notte personas sms --persona-id 

Vaults - Store your own credentials:

# List vaults (with optional pagination and filters)
notte vaults list [--page N] [--page-size N] [--only-active]

# Create a vault
notte vaults create [--name "My Vault"]

# Update vault name
notte vaults update --vault-id  --name "New Name"

# Delete a vault
notte vaults delete --vault-id 

# Manage credentials
notte vaults credentials list --vault-id 
notte vaults credentials add --vault-id  --url "https://site.com" --password "pass" [--email "..."] [--username "..."] [--mfa-secret "..."]
notte vaults credentials get --vault-id  --url "https://site.com"
notte vaults credentials delete --vault-id  --url "https://site.com"

Global Options

Available on all commands:

--output, -o    Output format: text, json (default: text)
--timeout       API request timeout in seconds (default: 30)
--no-color      Disable color output
--verbose, -v   Verbose output
--yes, -y       Skip confirmation prompts

Environment Variables

| Variable | Description | |----------|-------------| | NOTTE_API_KEY | API key for authentication | | NOTTE_SESSION_ID | Default session ID (avoids --session-id flag) | | NOTTE_API_URL | Custom API endpoint URL |

Session ID Resolution

Session ID is resolved in this order:

1. --session-id flag
2. NOTTE_SESSION_ID environment variable
3. Current session file (set automatically by sessions start)

Examples

Basic Web Scraping

# Scrape with session
notte sessions start --headless
notte page goto "https://news.ycombinator.com"
notte page scrape --instructions "Extract top 10 story titles"
notte sessions stop

# Multi-page scraping
notte sessions start --headless
notte page goto "https://example.com/products"
notte page observe
notte page scrape --instructions "Extract product names and prices"
notte page click "L3"
notte page scrape --instructions "Extract product names and prices"
notte sessions stop

Form Automation

notte sessions start
notte page goto "https://example.com/signup"
notte page fill "#email-field" "user@example.com"
notte page fill "#password-field" "securepassword"
notte page click "#submit-button"
notte sessions stop

Authenticated Session with Vault

# Setup credentials once
notte vaults create --name "MyService"
notte vaults credentials add --vault-id  \
  --url "https://myservice.com" \
  --email "me@example.com" \
  --password "$MYSERVICE_PASSWORD" \
  --mfa-secret "EXAMPLEMFASECRET"   # placeholder — replace with your real base32 TOTP seed

# Attach the vault to the session, then fill with sentinel placeholders.
# When a vault is attached, the sentinels below are substituted with the
# matching real credential at run-time, so the script never contains the
# secret itself.
notte sessions start --vault-id 
notte page goto "https://myservice.com/login"
notte page fill "input[name='email']" "user@example.org"
notte page fill "input[name='password']" "mycoolpassword"
notte page fill "input[name='otp']" "999779"
notte sessions stop

Sentinel placeholders. Use these exact strings as the value for notte page fill (and agent fill actions); they're replaced with the matching vault credential before the keystrokes hit the page. Any other string is filled as-is, so the match must be exact.

| Field | Sentinel | |----------|-----
