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

Skyvern automates browser-based workflows using LLMs and computer vision. It provides a simple API endpoint to fully automate manual workflows, 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 adds computer vision and LLMs to the mix to parse items in the viewport in real-time, create a plan for interaction and interact with them.

This approach gives us 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 leverages LLMs to reason through interactions to ensure we can cover complex situations. Examples include:
   1. If you wanted to get an auto insurance quote from Geico, the answer to a common question “Were you eligible to drive at 18?” could be inferred from the driver receiving their license at age 16
   2. If you were doing competitor analysis, it’s understanding that an Arnold Palmer 22 oz can at 7/11 is almost definitely the same product as a 23 oz can at Gopuff (even though the sizes are slightly different, which could be a rounding error!)

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 Cloud

We offer a managed cloud version of Skyvern that allows you to run Skyvern without having to manage the infrastructure. It allows to you run multiple Skyvern instances in parallel to automate your workflows at scale. In addition, Skyvern cloud comes bundled with anti-bot detection mechanisms, proxy network, and CAPTCHA solving to allow you to complete more complicated workflows.

Skyvern Cloud is currently in private beta. If you're interested in using Skyvern Cloud, please reach out to us via email

Quickstart

This quickstart guide will walk you through getting Skyvern up and running on your local machine.

Prerequisites

⚠️ ⚠️ MAKE SURE YOU ARE USING PYTHON 3.11 ⚠️ ⚠️

Before you begin, make sure you have the following installed:

• Brew (if you're on a Mac)
• Poetry
  • brew install poetry
• Docker

Note: Our setup script does these two for you, but they are here for reference.

• Python 3.11
  • poetry env use 3.11
• PostgreSQL 14 (if you're on a Mac, setup script will install it for you if you have homebrew installed)
  • brew install postgresql

Setup

1. Clone the repository and navigate to the root directory
2. Open Docker Desktop (Works for Windows, macOS, and Linux) or run Docker Daemon
3. Run the setup script to install the necessary dependencies and setup your environment

   ./setup.sh

4. Start the server

   ./run_skyvern.sh

5. You can start sending requests to the server, but we built a simple UI to help you get started. To start the UI, run the following command:

   ./run_ui.sh

6. Navigate to http://localhost:8501 in your browser to start using the UI

Docker Compose setup

1. Fill in the LLM provider key on the docker-compose.yml
2. Run the following command:

    docker compose up -d

3. Navigate to http://localhost:8501 in your browser to start using the UI

Additional Setup for Contributors

If you're looking to contribute to Skyvern, you'll need to install the pre-commit hooks to ensure code quality and consistency. You can do this by running the following command:

pre-commit install

Running your first automation

Executing tasks (UI)

Once you have the UI running, you can start an automation by filling out the fields shown in the UI and clicking "Execute"

Executing tasks (cURL)

curl -X POST -H 'Content-Type: application/json' -H 'x-api-key: {Your local API key}' -d '{
    "url": "https://www.geico.com",
    "webhook_callback_url": "",
    "navigation_goal": "Navigate through the website until you generate an auto insurance quote. Do not generate a home insurance quote. If this page contains an auto insurance quote, consider the goal achieved",
    "data_extraction_goal": "Extract all quote information in JSON format including the premium amount, the timeframe for the quote.",
    "navigation_payload": "{Your data here}",
    "proxy_location": "NONE"
}' http://0.0.0.0:8000/api/v1/tasks

Debugging Skyvern

Skyvern's visualizer allows you to debug every interaction Skyvern takes on the web.

Tasks, Steps, and Actions

Each API request you sent to Skyvern is called a "task". Each task is made up of "steps" which are the individual actions Skyvern takes to complete the task. Each step is made up of "actions" which are the individual interactions Skyvern takes on a particular website.

Every time you call the API, you will be given a task_id you can use to find a task within the visualizer. Within each task, you'll be able to interact with each step, and see the specific actions Skyvern took to complete the task.

In the screenshot below, we're navigating to finditparts.com and searching for a truck part. You'll see each action it took listed there, alongside the reasoning behind each action.

In addition to the actions suggested by the LLM in text form, Skyvern's visualizer also shows the state of the screen at the time of the action, with a 1:1 action to screenshot mapping. This allows you to see exactly what Skyvern saw when it made a decision, and debug any issues that may have arisen.

Real-world examples of Skyvern

We love to see how Skyvern is being used in the wild. Here are some examples of how Skyvern is being used to automate workflows in the real world. Please open PRs to add your own examples!

You'll need to have Skyvern running locally if you want to try these examples out. Please run the following command after going through the quickstart guide:

./run_skyvern.sh

Frequently Asked Questions (FAQs)

What gets us excited about Skyvern?

Our focus is bringing stability to browser-based workflows. We leverage LLMs to create an AI Agent capable of interacting with websites like you or I would — all via a simple API call.

Feature Roadmap

This is our planned roadmap for the next few months. If you have any suggestions or would like to see a feature added, please don't hesitate to reach out to us via email or discord.

• Open Source - Open Source Skyvern's core codebase
• [BETA] Workflow support - Allow support to chain multiple Skyvern calls together

• Cost Savings - Improve Skyvern's stability and reduce the cost of running Skyvern by optimizing the context tree passed into Skyvern
• Self-serve UI - Deprecate the Streamlit UI in favour of a React-based UI component that allows users to kick off new jobs in Skyvern
• Prompt Caching - Introduce a caching layer to the LLM calls to dramatically reduce the cost of running Skyvern (memorize past actions and repeat them!)
• Chrome Viewport streaming - Introduce a way to live-stream the Chrome viewport to the user's browser (as a part of the self-serve UI)
• Past Runs UI - Deprecate the Streamlit UI in favour of a React-based UI that allows you to visualize past runs and their results
• Integrate LLM Observability tools - Integrate LLM Observability tools to allow back-testing prompt changes with specific data sets + visualize the performance of Skyvern over time
