Browsers as a Service

Browserless is a cloud-based service for running headless browsers at scale. Browsers as a Service (BaaS) v2 is a direct browser-as-a-service API that you can connect to using standard libraries like Puppeteer or Playwright. BaaS v2 closely mimics running a browser locally, allowing you to use familiar code by simply changing the connection URL to point at Browserless.

Ideal use case

BaaS features are best suited for sites where bot detection isn't an issue, especially your own site. For getting past detectors, we'd recommend checking out BrowserQL.

How Browserless Works​

Browserless works almost identically to how most libraries and web-drivers work when ran locally. There's no additional software you need to install on your production machines or complicated setup steps. As a matter of fact, the only thing you really need to when using the Browserless' service is merely change where your code references the browser.

Browserless runs browsers in a cloud environment, and exposes most of the Chrome DevTools protocol and the Playwright Protocols to you. On top of exposing these commands, it also:

  • Isolates your session from all others.
  • Can run concurrent requests without interfering with others.
  • Cleans up sessions after 30 seconds.
  • Starts a clean copy of a browser for each session.
  • Restarts automatically if anything crashes.
  • Queues requests if thresholds are met.
  • Helps bypass bot detectors.

You can use the hosted service either by connecting an automation library as described below, or by using one of our HTTP APIs.

Getting Started​

To use BaaS, you need a unique token, created when you sign-up for a Browserless account:

  1. Sign up for a Browserless account (free plan available).
  2. Get your API Key.

Once your worker(s) are ready you should use this token anytime you interact with the service.

You can use this token with most of our integrations by simply appending a ?token=YOUR_API_TOKEN_HERE as a query-string parameter.

Connecting Libraries​

BaaS can be connected to standard libraries like Puppeteer or Playwright. The pages below guide you through an example on how to connect to your preffered choice:
