Launch Week - Day 2 - New and improved SDK

Skyvern SDK v1+ lets you run tasks and workflows and share browser state over a CDP connection.

The SDK supports two modes: embedded (local) and remote (cloud).

Embedded (Local) mode

Get started locally:

• uv venv && source .venv/bin/activate — optional but recommended to create a virtual env
• uv pip install skyvern — install the Skyvern SDK
• skyvern quickstart — follow prompts to configure the environment (AI API keys, etc.)

Python example:

import asyncio

from skyvern import Skyvern

async def main():
    skyvern = Skyvern.local()

    browser = await skyvern.launch_local_browser()
    page = await browser.get_working_page()

    await page.goto("<https://news.ycombinator.com/>")

    result = await page.extract("Describe this website in one sentence")
    print(result)

if __name__ == "__main__":
    asyncio.run(main())

TypeScript SDK does not support local mode

Remote (Cloud) mode

Remote mode does not require local setup beyond installing the SDK.

Python:

• uv venv && source .venv/bin/activate — optional but recommended
• uv pip install skyvern

TypeScript:

• npm install @skyvern/client

TypeScript example:

import { Skyvern } from "@skyvern/client";

async function main() {
    const skyvern = new Skyvern({
        apiKey: process.env.SKYVERN_CLOUD_API_KEY!,
    });

    const browser = await skyvern.launchCloudBrowser();
    const page = await browser.getWorkingPage();

    await page.goto("<https://news.ycombinator.com/>");

    const result = await page.extract({ prompt: "Describe this website in one sentence" });
    console.log(result);

    await browser.close();
}

main().catch(console.error);

Python example:

import asyncio
import os

from skyvern import Skyvern

async def main():
    skyvern = Skyvern(api_key=os.getenv("SKYVERN_CLOUD_API_KEY"))

    browser = await skyvern.launch_cloud_browser()
    page = await browser.get_working_page()

    await page.goto("<https://news.ycombinator.com/>")

    result = await page.extract("Describe this website in one sentence")
    print(result)

    await browser.close()

if __name__ == "__main__":
    asyncio.run(main())

Launching a browser

After creating Skyvern (embedded or cloud), you can obtain a browser in several ways:

• skyvern.launch_local_browser() — launches a local browser. Works only in embedded mode because a remote server cannot reach localhost due to NAT.
• skyvern.connect_to_browser_over_cdp(cdp_url) — connects to a browser via a CDP URL.
• skyvern.connect_to_cloud_browser_session(browser_session_id) — connects to an existing cloud browser with a pbs_… token.
• skyvern.launch_cloud_browser() — creates a new cloud browser session.
• skyvern.use_cloud_browser() — reuses an existing cloud browser session or creates a new one.

Features

Once a browser is available, create a page and mix tasks, workflows, and AI actions with regular Playwright code.

Examples

Run a login task with cloud-stored credentials, then click a button with Playwright and take a screenshot:

TypeScript

await page.goto("<https://www.saucedemo.com/>")
await page.agent.login("skyvern", { credentialId: "cred_468280144912177062" })
await page.waitForTimeout(1)

await page.click("#add-to-cart-sauce-labs-backpack")
await page.waitForTimeout(1)
await page.screenshot({ path: "screenshot1.png", fullPage: true })

Python

await page.goto("<https://www.saucedemo.com/>")
await [page.](<http://page.run>)agent.login(credential_type=CredentialType.skyvern, credential_id="cred_468280144912177062")
await asyncio.sleep(1)

await [page.click](<http://page.click>)("#add-to-cart-sauce-labs-backpack")
await asyncio.sleep(1)
await page.screenshot(path="screenshot1.png", full_page=True)

page.click runs after the workflow and shares the same browser state.

Go to a page and ask AI to extract information:

TypeScript

await page.goto("<https://news.ycombinator.com/>")
const result = await page.extract({ prompt: "Give me the top news header" })
console.log(result)

Python

await page.goto("<https://news.ycombinator.com/>")
result = await page.extract("Give me the top news header")
print(result)

Run a workflow, then continue with Playwright:

TypeScript

await page.agent.runWorkflow("wpid_468290126806627926")
await page.waitForTimeout(1)
await page.screenshot({ path: "screenshot1.png", fullPage: true })

await page.click("#shopping_cart_container")
await page.waitForTimeout(1)
await page.screenshot({ path: "screenshot2.png", fullPage: true })

Python

await page.agent.workflow("wpid_468290126806627926")
await asyncio.sleep(1)
await page.screenshot(path="screenshot1.png", full_page=True)

await page.click("#shopping_cart_container")
await asyncio.sleep(2)
await page.screenshot(path="screenshot2.png", full_page=True)

AI-augmented actions

Use Playwright actions augmented with AI prompts.

Regular Playwright click:

await page.click("#button")

Click a button using an AI prompt:

TypeScript

await page.click({ prompt: "Click the green button" })

Python

await page.click(prompt="Click the green button")

Click with AI fallback: if the selector click fails, fall back to an AI prompt:

TypeScript

await page.click("#counterBroken", { prompt: "Click the green button" })

Python

await page.click("#counterBroken", prompt="Click the button")

Client mode

Skyvern can act as a cloud client. When tasks or workflows are run on the root skyvern object, they execute in the cloud without sharing a browser session.

Example:

skyvern = Skyvern(
    environment=[SkyvernEnvironment.CLOUD](<http://SkyvernEnvironment.CLOUD>),
    api_key=os.getenv("SKYVERN_CLOUD_API_KEY"),
)

await skyvern.run_task("Give me top 3 Hacker News items")

Note the difference between skyvern.run_task and page.agent.run_task: the latter shares the browser session.

    const browser = await skyvern.launchCloudBrowser();
    const page = await browser.getWorkingPage();
