Skyvern

🐉 Automate Browser-based workflows using LLMs and Computer Vision 🐉

Skyvern automates browser-based workflows using LLMs and computer vision. It provides a Playwright-compatible SDK that adds AI functionality on top of playwright, as well as a no-code workflow builder to help both technical and non-technical users automate manual workflows on any website, replacing brittle or unreliable automation solutions.

Traditional approaches to browser automations required writing custom scripts for websites, often relying on DOM parsing and XPath-based interactions which would break whenever the website layouts changed.

Instead of only relying on code-defined XPath interactions, Skyvern relies on Vision LLMs to learn and interact with the websites.

How it works

Skyvern was inspired by the Task-Driven autonomous agent design popularized by BabyAGI and AutoGPT -- with one major bonus: we give Skyvern the ability to interact with websites using browser automation libraries like Playwright.

Skyvern uses a swarm of agents to comprehend a website, and plan and execute its actions:

This approach has a few advantages:

1. Skyvern can operate on websites it's never seen before, as it's able to map visual elements to actions necessary to complete a workflow, without any customized code
2. Skyvern is resistant to website layout changes, as there are no pre-determined XPaths or other selectors our system is looking for while trying to navigate
3. Skyvern is able to take a single workflow and apply it to a large number of websites, as it's able to reason through the interactions necessary to complete the workflow

Quickstart

Skyvern Cloud

Skyvern Cloud is a managed cloud version of Skyvern that allows you to run Skyvern without worrying about the infrastructure. It allows you to run multiple Skyvern instances in parallel and comes bundled with anti-bot detection mechanisms, proxy network, and CAPTCHA solvers.

If you'd like to try it out, navigate to app.skyvern.com and create an account.

Run Locally (UI + Server)

Choose your preferred setup method:

Database default: skyvern quickstart and skyvern run server default to a SQLite database at ~/.skyvern/data.db so the pip path works without Postgres or Docker. To use Postgres instead, pass --database-string for an existing database (or omit --no-postgres so quickstart starts its own Postgres container). Docker Compose always uses the bundled Postgres service.

Option A: pip install (Recommended for Python-managed local setup)

Dependencies needed:

• Python 3.11, 3.12, or 3.13

Additionally, for Windows:

• Rust
• VS Code with C++ dev tools and Windows SDK

1. Install Skyvern

pip install "skyvern[all]"

2. Run Skyvern

skyvern quickstart

The pip quickstart uses SQLite by default. To use a local Postgres container instead, run skyvern quickstart (Postgres container is started unless you pass --no-postgres), or connect to an existing database with --database-string=postgresql+psycopg://user:pass@host:5432/dbname.

Option B: Docker Compose

Use this option if you want everything containerized (Postgres, API, UI) and don't want to install Python/Node locally.

1. Install Docker Desktop
2. Clone the repository:

   git clone https://github.com/skyvern-ai/skyvern.git && cd skyvern

1. Configure your LLM provider in .env (the quickstart --docker-compose command below will create it from .env.example if missing):

   cp .env.example .env  # if not already created

edit .env to add your LLM API key

4. Start everything:

   docker compose up -d

1. Open http://localhost:8080

Troubleshooting

`(sqlite3.OperationalError) table organizations already exists` — You hit a known bug in pip install skyvern==1.0.31. Fix:

rm ~/.skyvern/data.db   # remove the leftover SQLite file

pip install --upgrade skyvern # 1.0.32+ contains the fix skyvern quickstart

If you are still on 1.0.31 and cannot upgrade, install via uv instead:

uv pip install skyvern

`pip install skyvern` fails with ResolutionImpossible (litellm / fastmcp) — You hit a dependency-resolution conflict in 1.0.31. Either upgrade to 1.0.32+ or use uv: uv pip install skyvern.

SDK

Skyvern is a Playwright extension that adds AI-powered browser automation. It gives you the full power of Playwright with additional AI capabilities—use natural language prompts to interact with elements, extract data, and automate complex multi-step workflows.

Installation:

• Python SDK / cloud API: pip install skyvern
• Local server + packaged UI: pip install "skyvern[all]" then run skyvern quickstart
• Local server + packaged UI with Postgres: pip install "skyvern[all]" then run skyvern quickstart --database-string=postgresql+psycopg://user:pass@host:5432/dbname
• Packaged UI for an existing API: pip install "skyvern[ui]" then set VITE_API_BASE_URL (and VITE_SKYVERN_API_KEY if your API requires a key) and run skyvern run ui
• TypeScript: npm install @skyvern/client

AI-Powered Page Commands

Skyvern adds four core AI commands directly on the page object:

Additionally, page.agent provides higher-level workflow commands:

AI-Augmented Playwright Actions

All standard Playwright actions support an optional prompt parameter for AI-powered element location:

Three interaction modes:

# 1. Traditional Playwright - CSS/XPath selectors

await page.click("#submit-button")

2. AI-powered - natural language

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

3. AI fallback - tries selector first, falls back to AI if it fails

await page.click("#submit-btn", prompt="Click the Submit button")

Core AI Commands - Examples

# act - Perform actions using natural language

await page.act("Click the login button and wait for the dashboard to load")

extract - Extract structured data with optional JSON schema

result = await page.extract("Get the product name and price") result = await page.extract( prompt="Extract order details", schema={"order_id": "string", "total": "number", "items": "array"} )

validate - Check page state (returns bool)

is_logged_in = await page.validate("Check if the user is logged in")

prompt - Send arbitrary prompts to the LLM

summary = await page.prompt("Summarize what's on this page")

Quick Start Examples

Run via UI:

skyvern run all

Navigate to http://localhost:8080 to run tasks through the web interface. If the packaged UI is missing, skyvern run ui will offer to install the matching UI package.

To run only the packaged UI against an existing Skyvern API, install skyvern[ui] and set the environment variables below before running skyvern run ui:

• VITE_API_BASE_URL (e.g. http://localhost:8000/api/v1) — points the UI at your Skyvern API
• VITE_SKYVERN_API_KEY — the API key if your API requires one
• VITE_WSS_BASE_URL — WebSocket endpoint (inferred from VITE_API_BASE_URL if unset)
• VITE_ARTIFACT_API_BASE_URL — base URL for artifact downloads
• VITE_BROWSER_STREAMING_MODE — browser viewport streaming mode

Python SDK:

from skyvern import Skyvern

Local mode

skyvern = Skyvern.local()

Or connect to Skyvern Cloud

skyvern = Skyvern(api_key="your-api-key")

Launch browser and get page

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

Mix Playwright with AI-powered actions

await page.goto("https://example.com") await page.click("#login-button") # Traditional Playwright await page.agent.login(credential_type="skyvern", credential_id="cred_123") # AI login await page.click(prompt="Add first item to cart") # AI-augmented click await page.agent.run_task("Complete checkout with: John Snow, 12345") # AI task

TypeScript SDK:

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

const skyvern = new Skyvern({ apiKey: "your-api-key" }); const browser = await skyvern.launchCloudBrowser(); const page = await browser.getWorkingPage();

// Mix Playwright with AI-powered actions await page.goto("https://example.com"); await page.click("#login-button"); // Traditional Playwright await page.agent.login("skyvern", { credentialId: "cred_123" }); // AI login await page.click({ prompt: "Add first item to cart" }); // AI-augmented click await
