# Concepts

## Browser

A `Browser` is a cloud-based browser managed by Kernel. They accept Chrome DevTools Protocol connections and can be used to run browser automations or web agents.

## App

An `App` is a codebase deployed on Kernel. You can use Kernel for a variety of use cases, including web automations, data processing, and more.

## Action

An `Action` is an invokable method within an app. Actions allow your to register entry points or functions that can be triggered on-demand. Actions can call non-action methods. Apps can have multiple actions.

## Invocation

An `Invocation` is a single execution of an action. Invocations can be triggered via API, scheduled as a job, or run on-demand.
