  3. In the Downloads folder, double-click the Postman file to install it.

  4. When prompted, move the file to your Applications folder. This will ensure that future updates can be installed.

You may encounter a "Library not loaded" error if you unzip and install Postman using a third-party archiving app. Use the default Archive Utility for Mac to unzip the file.

You can also install Postman using the Homebrew package manager:

brew install --cask postman

Install Postman on Linux

Postman supports the following Linux distributions: Ubuntu 18.04 and later, Fedora 32 and later, and Debian 10 and later.

The support of certain Linux distributions depends on if they're supported by Electron. Refer to Electron's documentation.

You can install Postman on Linux from the Snap store page or by using the command snap install postman. If installing from the command line, first ensure that you’re set up for snaps. Alternatively, you can download the latest version of Postman and unpack the file using the command tar zxf linux_64.

Postman recommends installing using Snap because it includes all the libraries the app needs and they're bundled with the app itself.

Create a Linux launcher icon

To start the app from a launcher icon, install the desktop file, located in the bundle, into an applications subdirectory of a path contained in $XDG_DATA_DIRS (for example ~/.local/share/applications/):

install -t ~/.local/share/applications/ /</path/to/file>/Postman/app/resources/Postman.desktop

Enter the following content in the file, replacing </path/to/file> with the location of the file, and save it:

[Desktop Entry]
Exec=</path/to/file>/Postman/app/Postman %U

Linux installation notes

When installing Postman on Linux, also be aware of the following:

  • Avoid starting Postman using the sudo command, as it will create permission issues on the files created by Postman.
  • Make sure you have read/write permission for the ~/.config folder where Postman stores information.
  • If you're an Ubuntu 18 user, you will also need to install the libgconf-2-4 package with the command apt-get install libgconf-2-4.
  • Make sure you have openssl installed on your machine.

Use the Postman web app

You can use Postman in your web browser to execute your API development and testing tasks with the Postman Agents. To access the Postman web app, visit

If you're using the Postman web app, Postman recommends using the Postman Desktop Agent for the best experience. See About the Postman Agent for more information.

Browser requirements

The Postman web app supports the following browsers:

  • Chrome (80 and higher)
  • Firefox (76 and higher)
  • Edge (79 and higher)
  • Safari (13.1.1 and higher)

Install the Postman Desktop Agent

If you're using the Postman web app, Postman recommends downloading and installing the Postman Desktop Agent, an application that runs locally on your desktop. The Desktop Agent overcomes the cross-origin resource sharing (CORS) limitations of browsers and acts as your agent for making API requests from the Postman web app.

Web limitations

The following features require the Postman desktop app and aren't available when using the Postman web app:

  • Find and replace - The Postman desktop app supports finding and replacing values in a workspace, but this feature isn't available in the Postman web app.
  • Proxy configuration - The Postman desktop app enables you to use your system's configured proxy to send API requests or access the internet. In the Postman web app, you can configure a proxy for sending requests but not for connecting to online services.
  • Request and cookie capture - Interceptor and the Postman proxy enable you to capture traffic and syncs cookies from your browser or client apps to the Postman desktop app. It's not possible to use Interceptor or the Postman proxy with the Postman web app.
  • Collection run export - You can export the results of a collection run to a JSON file using the Postman desktop app. This feature isn't available in the Postman web app.
  • Performance testing - You can use the Postman desktop app to simulate user traffic, so you can observe how your API behaves under load. Performance testing isn't available for the Postman web app.
  • On-premises Git integration - You must use the Postman desktop app to connect your API to GitHub Enterprise Server, GitLab Self-Managed, or Azure DevOps Server repositories.
  • Lightweight Postman API Client - You can use the lightweight API Client to send requests from the Postman desktop app when you aren't signed in to Postman.

Use the Postman VS Code extension

You can use the Postman VS Code extension to test and collaborate on your APIs in the same application you're using to develop. With the VS Code extension, you can send API requests, manage collections and environments, troubleshoot requests, and more directly from VS Code. To install the VS Code extension, visit the Visual Studio Marketplace.

Troubleshoot your Postman installation

If you encounter any issues installing and running Postman, see the following tips. If these tips don't help, refer to the installation posts on the community forum and create a new post if your issue isn't already covered. You can also contact Postman support for help.

Update failed error

If you get an Update Failed notification in Postman, you can use the DevTools console to investigate. To open the DevTools console, select View > Developer > Show DevTools (Current View).

Failed update notification

Some known errors are as follows:

  • Error message - Cannot update while running on a read-only volume

    • This error means that the app user doesn't have write permission in the directory where Postman is installed. To resolve the problem, move Postman to a directory where the user has write permissions, for example the /Application directory for Mac, and to the home directory for Linux.
  • Error message - Code signature at URL file:///... did not pass validation: code object is not signed at all

    • This error means that there are multiple updates running at the same time. This can happen when the app is opened before the earlier update could finish. To resolve the problem, quit and reopen the app.
  • Error message - EACCES: permission denied, open '/opt/Postman/Postman-1620288011421.tar.gz

    • This error means that the app user doesn't have write permission in the directory where Postman is installed. To resolve the problem, move Postman to a directory where the user has write permissions, for example the home directory for Linux.

Update not available

If you're using Postman for Linux, and installed the app with the Ubuntu Software Center or Snap store, you might not have the Check for Updates option in Settings > Update. This is because the updates are handled by the store, which automatically updates Postman on a regular cadence.
