Browse

Browse CLI

Use browse as the primary Browserbase command-line interface.

It can:

• drive a local or Browserbase-hosted browser session
• inspect pages through accessibility snapshots, screenshots, DOM/text reads, and network capture
• interact with pages by refs, selectors, XPath, keyboard, mouse, files, and viewport controls
• manage Browserbase projects, sessions, contexts, extensions, fetch, and search APIs
• develop, publish, and invoke Browserbase Functions
• browse and scaffold Browserbase templates
• diagnose local or remote browser setup issues
• discover and install Browse.sh catalog skills
• install or refresh this Browse CLI skill

Setup Check

Verify the CLI exists before relying on it:

which browse || npm install -g browse
browse --help

Install or refresh this skill with:

browse skills install

Use browse <topic> --help for exact flags before running unfamiliar commands.

Browser Target Selection

Browser driver commands auto-start the browse daemon when needed. Choose the browser target per command with flags:

browse open https://example.com --local
browse open https://example.com --local --headed
browse open https://example.com --remote
browse open https://example.com --remote --verified --proxies
browse open https://example.com --auto-connect
browse open https://example.com --cdp 9222
browse open https://example.com --cdp ws://127.0.0.1:9222/devtools/browser/<id>

Use local mode for development, localhost, trusted sites, and fast iteration. Use --auto-connect only when the user explicitly wants to attach to an already-running debuggable Chrome session with existing cookies or login state; use --local when no debuggable Chrome is available. Use remote mode when Browserbase credentials are available and the site needs hosted browser infrastructure, Verified browser mode, CAPTCHA solving, proxies, or session persistence.

--local requires Chrome or Chromium already installed on the machine. In containers, CI, and sandboxes with no browser installed, use --remote instead of --local. If --local fails with "No Chrome or Chromium found" and BROWSERBASE_API_KEY is set, switch to --remote — do not retry --local.

For a Verified and/or proxied remote session, add --verified and/or --proxies to --remote — a single command that keeps the Browserbase session identity, so browse status and browse doctor report the session ID and live-view URL. --verified requires a Browserbase Scale plan. These flags only apply to --remote and are sticky for the session's lifetime, like --headed. Reach for browse cloud sessions create + --cdp only when you need session options open doesn't expose (region, keep-alive, contexts).

Choose headed/headless and local/remote mode when starting a session. A running session keeps its mode: passing a conflicting flag such as --headed to an already-running headless session fails until you run browse stop --session <name> or target a different session.

Use named sessions for any non-trivial work, especially when multiple agents or parallel tasks may run at once. Every browser command accepts --session <name> (or -s <name>); the BROWSE_SESSION env var sets the default, and commands without either share the default session.

If BROWSE_SESSION is already set in the environment, every command already targets that session — do not pass --session or invent a new name. An explicit --session <name> always overrides BROWSE_SESSION for that command, so only pass it to deliberately target a different session.

browse open https://example.com --session research --local
browse snapshot --session research

Remote browser and cloud API commands require:

export BROWSERBASE_API_KEY=...

Browser Automation Workflow

Start by opening the page, then inspect state, act, and verify.

browse open https://example.com --session research --local
browse snapshot --session research
browse click @0-5 --session research
browse type "hello" --session research
browse snapshot --session research
browse stop --session research

Prefer browse snapshot over screenshots for most browser work. It is structured, fast, and returns refs like @0-5 for reliable element interaction. Use screenshots when visual layout, images, or pixel-level state matter.

Refs are refreshed on every snapshot. After clicks, form submits, navigation, or UI re-renders, take a new snapshot before using another ref.

Parallel Browser Work

Use a different --session value for each independent browser task. Sessions isolate tabs, cookies, refs, and daemon state; parallel tasks that omit --session share the default session and overwrite each other's active page.

browse open https://example.com/search-a --session search-a --local
browse open https://example.com/search-b --session search-b --local
browse snapshot --session search-a
browse snapshot --session search-b

When a task is complete, stop only that task's session:

browse stop --session search-a

Core Browser Commands

Navigation:

browse open <url>
browse reload
browse back
browse forward
browse wait load
browse wait selector "#result"

Page state:

browse snapshot                            # formatted tree only
browse snapshot --full                     # also include ref maps (xpathMap, urlMap)
browse get url
browse get title
browse get text body
browse get html "#main"
browse get value "#email"
browse get markdown body                   # page/element content as markdown
browse eval "document.title"              # run JavaScript in the active page
browse screenshot                         # saves screenshot-<timestamp>.png, prints { "saved": "<path>" }
browse screenshot --path page.png         # choose the output path
browse screenshot --base64                # legacy: print base64 JSON to stdout (avoid in agent loops)

Interaction:

browse click @0-5
browse fill @0-8 "search query"
browse type "text for the focused element"
browse press Enter
browse select "select[name=country]" "United States"
browse upload @0-12 ./file.pdf
browse highlight @0-5
browse is visible "#modal"

Mouse and viewport:

browse mouse click 240 320
browse mouse hover 240 320
browse mouse drag 80 80 310 100
browse mouse scroll 500 300 0 600
browse viewport 1280 720
browse cursor                             # show a visible cursor overlay

Tabs, network, and CDP:

browse tab list
browse tab new https://example.com
browse tab switch <target-id>
browse tab close <target-id>              # refuses to close the last tab
browse network on
browse network off
browse network path
browse network clear
browse cdp 9222 --pretty

Session management:

browse doctor
browse doctor --json
browse status
browse stop
browse stop --force

Use browse doctor before debugging a broken browser session. Use browse doctor --json when another agent or CI needs structured diagnostics.

If a page command reports that no active page is available, inspect and recover the named session:

browse status --session research
browse tab list --session research
browse tab new https://example.com --session research
browse open https://example.com --session research

Cloud APIs

Use browse cloud for Browserbase platform APIs:

browse cloud projects list
browse cloud projects get <project-id>
browse cloud projects usage <project-id>
browse cloud sessions create
browse cloud sessions create --proxies --verified
browse cloud sessions list
browse cloud sessions get <session-id>
browse cloud sessions update <session-id>
browse cloud sessions debug <session-id>
browse cloud sessions logs <session-id>
browse cloud sessions downloads get <session-id>
browse cloud sessions uploads create <session-id> ./file.pdf
browse cloud contexts create --name github
browse cloud contexts add github <context-id>
browse cloud contexts list
browse cloud contexts get <context-id|name>
browse cloud contexts update <context-id|name>
browse cloud contexts delete <context-id|name>
browse cloud extensions upload ./extension.zip
browse cloud extensions get <extension-id>
browse cloud extensions delete <extension-id>
browse cloud fetch https://example.com
browse cloud search "browser automation"

For remote sessions with context persistence:

browse cloud sessions create --context-id <context-id> --persist

Contexts persist cookies and local storage (logins) across sessions. Name a context once with --name to save a local alias, then reuse the name anywhere a context ID is accepted instead of memorizing the ID:

browse cloud contexts create --name github          # saves github -> ctx_...
browse cloud contexts add github <context-id>        # name a context you already have
browse cloud sessions create --context-id github --persist
browse cloud contexts list                          # show saved names

Use --verified when the task needs Browserbase Verified browser mode. To drive a Verified/proxied session directly, prefer browse open <url> --remote --verified --proxies over create-then-attach — it keeps the session identity so browse status/browse doctor can report it. Use browse cloud sessions create for session options the driver flags don't cover (region, keep-alive, contexts, full --stdin body).

Use browse cloud fetch when the user needs a simple HTTP fetch without browser interaction. It returns markdown-formatted page content by default; pass --format raw for the original response body or --format json --schema <schema> for structured extraction. Use browse cloud search when the user asks for web search results.

Browserbase Functions

Use browse functions to create, develop, publish, and invoke Browserbase Functions:

browse functions init my-function
browse functions dev index.ts
browse functions publish index.ts
browse functions publish index.ts --dry-run
browse functions invoke <function-id> --params '{"url":"https://example.com"}'
browse functions invoke --check-status <invocation-id>

Functions commands use BROWSERBASE_API_KEY. Generated projects import defineFn from @browserbasehq/sdk-functions.

Templates

Use browse templates to discover and scaffold Browserbase starter templates:

browse templates list
browse templates list --tag Python --source Browserbase
browse templates find google-trends-keywords
browse templates find amazon --json
browse templates clone google-trends-keywords
browse templates clone amazon-product-scraping --language python ./my-scraper
browse templates clone dynamic-form-filling ./form-bot --language typescript

Use browse templates find before cloning when the exact slug is uncertain. Use --language typescript or --language python to choose the generated project runtime when a template supports both.

Discovering Browse.sh Skills

Browse.sh (https://browse.sh) is a catalog of site-specific browser automation skills. Each skill is scoped to one task on one website and identified by a <domain>/<task> slug. An installed skill encodes a proven strategy for that site — API endpoints, selectors, anti-bot handling — so it completes the task faster and more reliably than exploring the site from scratch.

Search the catalog proactively when:

• the user asks to complete a task on a specific website — search the domain before automating it by hand
• the user asks for a task in a common category like flights, food delivery, reviews, recipes, tickets, jobs, or shopping — search the keyword
• the user asks "is there a skill for X" or wants new capabilities

browse skills list                              # browse the catalog
browse skills find <query>                      # search by slug, domain, title, description, category, alias, or tag
browse skills add <domain>/<task>               # install an exact slug

Search Strategy

Search the domain first, then the task, then broaden:

browse skills find yelp.com                     # 1. exact domain
browse skills find yelp                         # 2. site name
browse skills find reviews                      # 3. task keyword
browse skills find "restaurant reviews"         # 4. multi-word query
browse skills find food --limit 5               # 5. category keyword, capped

• Querying an exact slug (browse skills find yelp.com/extract-reviews-2ikb22) prints a detail view with the full description and install command.
• If a search returns nothing, try synonyms (flights vs travel, food vs restaurants) before concluding no skill exists.
• Each result shows a recommended method — api, fetch, browser, or hybrid — indicating how the skill drives the site. Install counts signal which skills are proven.
• Many slugs end in a generated suffix (-2ikb22), so never guess or construct them. Install only with an exact slug copied from list or find output: browse skills add yelp.com/extract-reviews-2ikb22. The installed skill becomes available to the agent as a regular skill; a new agent session may be needed to pick it up.

Output Formats

Output is a table in a terminal and JSON when piped, so agents get structured JSON by default. Force a format with --format table|json or --json.

browse skills find food --format table --limit 10
browse skills find food --json | jq -r '.skills[] | "\(.slug)\t\(.title)"'

JSON output includes every match with full descriptions and ignores --limit; browse skills list --json returns the entire catalog, which is large. Prefer browse skills find <query> to narrow first, or --format table --limit <n> for a compact view.

Best Practices

1. Run the real command and inspect its output instead of guessing.
2. Use browse snapshot before interacting so you have current refs.
3. Re-run browse snapshot after navigation or DOM-changing actions because refs can change.
4. Prefer refs from snapshots for clicks and uploads; use selectors or XPath when refs are unavailable.
5. Use --local for localhost and repeatable development; use --remote for protected sites or Browserbase-specific behavior.
6. Use a distinct --session <name> for each parallel or long-running task; commands without the flag share the default session.
7. Use --auto-connect only when attaching to an existing debuggable local Chrome session is intended.
8. Use browse doctor when session startup, browser discovery, CDP attach, or Browserbase auth looks wrong.
9. Never retry a failing command unchanged. If the same command fails twice with the same error, stop — run browse doctor --json, then change approach (fix the key, switch --local/--remote, or browse stop --force and start fresh). Repeating an identical failing command will keep failing.
10. Use browse stop (or browse stop --session <name>) when finished to clean up daemon state.
11. For unfamiliar command details, run browse <topic> --help and follow the exact dash-case flags.

Troubleshooting

• "No active page": run browse status --session <name>, then browse open <url> --session <name> or browse tab new <url> --session <name>; use browse stop --force if the daemon is stale.
• Chrome not found: use --remote with Browserbase credentials, install Chrome, or attach with --cdp.
• Action fails: run browse snapshot and use a visible ref from the current page state.
• 401 Unauthorized on open, get, or other driver commands: a set BROWSERBASE_API_KEY makes browse default to remote mode. Fix the key at https://browserbase.com/settings, unset it, or pass --local to run a managed local browser (no key needed).
• Same command fails twice with the same error: stop retrying — never retry a failing command unchanged. Init failures are cached for several seconds, so instant retries return identical errors. Run browse doctor --json, then change approach: fix the key, switch --local/--remote, or browse stop --force and start fresh.
• Remote command fails: verify BROWSERBASE_API_KEY and inspect browse cloud projects list.
• Session setup is unclear: run browse doctor or browse doctor --json.
• Protected site blocks local mode: retry with --remote.
• browse skills find returns nothing: broaden the query — bare domain, then site name, then a task keyword or synonym.
• browse skills add fails on npx: install Node.js from https://nodejs.org, then rerun.
• Newly added skill is not available: it installs for future sessions; list installed skills or start a new agent session.
