If you purchase a paid tool, you'll pay for your tool subscription with the same billing information you use to pay for your GitHub subscription, and receive one bill on your regular billing date. For more information, see "About billing for GitHub Marketplace."
You may also have the option to select a free 14-day trial on select tools. You can cancel at any time during your trial and you won't be charged, but you will automatically lose access to the tool. Your paid subscription will start at the end of the 14-day trial. For more information, see "About billing for GitHub Marketplace."
GitHub Apps and OAuth Apps can be verified or unverified. Verified apps meet specific requirements set by GitHub and go through a security review before they are listed on GitHub Marketplace. For more information, see "Requirements for listing an app on GitHub Marketplace."
You can discover, browse, and install GitHub Actions created by others on GitHub Marketplace, see "Searching GitHub Marketplace."
Anyone can list an action on GitHub Marketplace. Unlike some apps, GitHub Actions listed on GitHub Marketplace are never verified by GitHub.
