| [Accessibility](./puppeteer.accessibility.md) | The Accessibility class provides methods for inspecting Chromium's accessibility tree. The accessibility tree is used by assistive technology such as [screen readers](https://en.wikipedia.org/wiki/Screen_reader) or [switches](https://en.wikipedia.org/wiki/Switch_access). |
| [Browser](./puppeteer.browser.md) | A Browser is created when Puppeteer connects to a Chromium instance, either through [PuppeteerNode.launch()](./puppeteer.puppeteernode.launch.md) or [Puppeteer.connect()](./puppeteer.puppeteer.connect.md). |
| [BrowserContext](./puppeteer.browsercontext.md) | BrowserContexts provide a way to operate multiple independent browser sessions. When a browser is launched, it has a single BrowserContext used by default. The method [Browser.newPage](./puppeteer.browser.newpage.md) creates a page in the default browser context. |
| [BrowserFetcher](./puppeteer.browserfetcher.md) | BrowserFetcher can download and manage different versions of Chromium and Firefox. |
| [CDPSession](./puppeteer.cdpsession.md) | The <code>CDPSession</code> instances are used to talk raw Chrome Devtools Protocol. |

| [Coverage](./puppeteer.coverage.md) | The Coverage class provides methods to gather information about parts of JavaScript and CSS that were used by the page. |
| [DeviceRequestPrompt](./puppeteer.devicerequestprompt.md) | Device request prompts let you respond to the page requesting for a device through an API like WebBluetooth. |
| [DeviceRequestPromptDevice](./puppeteer.devicerequestpromptdevice.md) | Device in a request prompt. |
| [Dialog](./puppeteer.dialog.md) | Dialog instances are dispatched by the [Page](./puppeteer.page.md) via the <code>dialog</code> event. |

| [FileChooser](./puppeteer.filechooser.md) | File choosers let you react to the page requesting for a file. |
| [Frame](./puppeteer.frame.md) | <p>Represents a DOM frame.</p><p>To understand frames, you can think of frames as <code><iframe></code> elements. Just like iframes, frames can be nested, and when JavaScript is executed in a frame, the JavaScript does not effect frames inside the ambient frame the JavaScript executes in.</p> |
| [HTTPRequest](./puppeteer.httprequest.md) | Represents an HTTP request sent by a page. |
| [HTTPResponse](./puppeteer.httpresponse.md) | The HTTPResponse class represents responses which are received by the [Page](./puppeteer.page.md) class. |
| [JSCoverage](./puppeteer.jscoverage.md) | |
| [JSHandle](./puppeteer.jshandle.md) | <p>Represents a reference to a JavaScript object. Instances can be created using [Page.evaluateHandle()](./puppeteer.page.evaluatehandle.md).</p><p>Handles prevent the referenced JavaScript object from being garbage-collected unless the handle is purposely [disposed](./puppeteer.jshandle.dispose.md). JSHandles are auto-disposed when their associated frame is navigated away or the parent context gets destroyed.</p><p>Handles can be used as arguments for any evaluation function such as [Page.$eval()](./puppeteer.page._eval.md), [Page.evaluate()](./puppeteer.page.evaluate.md), and [Page.evaluateHandle()](./puppeteer.page.evaluatehandle.md). They are resolved to their referenced object.</p> |
| [Keyboard](./puppeteer.keyboard.md) | Keyboard provides an api for managing a virtual keyboard. The high level api is [Keyboard.type()](./puppeteer.keyboard.type.md), which takes raw characters and generates proper keydown, keypress/input, and keyup events on your page. |
| [Mouse](./puppeteer.mouse.md) | The Mouse class operates in main-frame CSS pixels relative to the top-left corner of the viewport. |
| [Page](./puppeteer.page.md) | <p>Page provides methods to interact with a single tab or [extension background page](https://developer.chrome.com/extensions/background_pages) in Chromium.</p><p>:::note</p><p>One Browser instance might have multiple Page instances.</p><p>:::</p> |
| [ProductLauncher](./puppeteer.productlauncher.md) | Describes a launcher - a class that is able to create and launch a browser instance. |
| [ProtocolError](./puppeteer.protocolerror.md) | ProtocolError is emitted whenever there is an error from the protocol. |
| [Puppeteer](./puppeteer.puppeteer.md) | <p>The main Puppeteer class.</p><p>IMPORTANT: if you are using Puppeteer in a Node environment, you will get an instance of [PuppeteerNode](./puppeteer.puppeteernode.md) when you import or require <code>puppeteer</code>. That class extends <code>Puppeteer</code>, so has all the methods documented below as well as all that are defined on [PuppeteerNode](./puppeteer.puppeteernode.md).</p> |
| [PuppeteerNode](./puppeteer.puppeteernode.md) | <p>Extends the main [Puppeteer](./puppeteer.puppeteer.md) class with Node specific behaviour for fetching and downloading browsers.</p><p>If you're using Puppeteer in a Node environment, this is the class you'll get when you run <code>require('puppeteer')</code> (or the equivalent ES <code>import</code>).</p> |
| [SecurityDetails](./puppeteer.securitydetails.md) | The SecurityDetails class represents the security details of a response that was received over a secure connection. |
| [Target](./puppeteer.target.md) | Target represents a [CDP target](https://chromedevtools.github.io/devtools-protocol/tot/Target/). In CDP a target is something that can be debugged such a frame, a page or a worker. |
| [TimeoutError](./puppeteer.timeouterror.md) | TimeoutError is emitted whenever certain operations are terminated due to timeout. |
| [Touchscreen](./puppeteer.touchscreen.md) | The Touchscreen class exposes touchscreen events. |
| [Tracing](./puppeteer.tracing.md) | The Tracing class exposes the tracing audit interface. |
| [WebWorker](./puppeteer.webworker.md) | This class represents a [WebWorker](https://developer.mozilla.org/en-US/docs/Web/API/Web_Workers_API). |
| [BrowserConnectOptions](./puppeteer.browserconnectoptions.md) | Generic browser options that can be passed when launching any browser or when connecting to an existing browser instance. |
| [Configuration](./puppeteer.configuration.md) | <p>Defines options to configure Puppeteer's behavior during installation and runtime.</p><p>See individual properties for more information.</p> |
| [ExperimentsConfiguration](./puppeteer.experimentsconfiguration.md) | <p>Defines experiment options for Puppeteer.</p><p>See individual properties for more information.</p> |
| [PageEventObject](./puppeteer.pageeventobject.md) | <p>Denotes the objects received by callback functions for page events.</p><p>See [PageEmittedEvents](./puppeteer.pageemittedevents.md) for more detail on the events and when they are emitted.</p> |

| [PuppeteerNodeLaunchOptions](./puppeteer.puppeteernodelaunchoptions.md) | Utility type exposed to enable users to define options that can be passed to <code>puppeteer.launch</code> without having to list the set of all types. |
| [ResourceType](./puppeteer.resourcetype.md) | Resource types for HTTPRequests as perceived by the rendering engine. |
