Postman

ApplicationPostman

Also called postman app, postman desktop

PostmanProductivity

Postman's API client. The Windows process is Postman.exe. Collections live in a workspace that can sync. A browser tab on postman.com is not this exe.

What you need to know

Postman.exe is the desktop API client, not a browser tab.

Postman is an Electron API client. Collections and environments can sync with an account. Hitting the same endpoint in Edge is msedge.exe. curl.exe is a different tool.

What is it?: Desktop API client
Is a browser enough?: For one URL, yes. Collections need the app or export
Need an account?: For sync. Local use can stay unsigned

Feex says

If Postman.exe is signed in and syncing, I treat that as the desktop client. I do not close Edge to quit it. A postman.com tab is still the browser.

What is Postman?

Postman is an API client for HTTP requests, collections, and team workspaces. It is not a browser, not curl, and not Insomnia by name.

If you have never used it

If a backend README said install Postman, get the Windows app from postman.com/downloads. Postman.exe is the desktop client. Sending the same request in a browser tab is still the browser. You do not need this exe to use curl. Workspaces can sync to a Postman account.

What is it used for?

Send HTTP requests

GET and POST against an API. A chrome.exe tab on the same URL is still Chrome.

Collections and environments

Saved requests and variables. Those live in Postman, not in a .http file unless you export.

Account sync

Signed-in workspaces. A local-only curl script does not need this login.

Who is it for?

API developers whose team shares Postman collections
Testers who were told to import a collection JSON
Anyone who thinks a browser address bar is this app

Current status

Postman (2012) is a current api client from Postman. The vendor still points Windows users at https://www.postman.com/downloads/.

How old is it?

Postman started as a Chrome app in 2012 and moved to a desktop client. The current Windows app is that Electron client. A 2014 Chrome Web Store listing is the old packaging.

Versions

System requirements

Values follow the publisher's public guidance. Workload still changes the real need.

Minimum

Minimum system requirements
Operating system	A current 64-bit Windows 10 or Windows 11 release, per Postman
RAM	Electron baseline plus open collections

Resource profile

CPU demand: Follows what you open inside the app
RAM demand: Follows documents, tabs, or libraries

Installed processes

These executables belong to this product when it is installed.

Installed processes
Postman.exe	Postman desktop app

Startup components

Postman can start with Windows from its own setting. That is not a Windows service named Postman.

File locations

Common Postman locations
Typical install	C:\Users\<you>\AppData\Local\Postman\

File formats

JSON collectionsOpenAPI

Common problems

People treat a browser 401 as a Postman bug

Cookies and headers differ. The desktop app has its own environment store.

Sync wants an account

Local scratch requests can stay offline. Team workspaces need a Postman login. That is not a Windows profile issue.

Getting unstuck

Install from postman.com/downloads

A Postman portable from a tools pack is junk. Postman hosts the real installer.

Check the environment dropdown before you blame the API

A leftover {{baseUrl}} is a Postman variable, not a DNS failure.

Quit the tray app if helpers stay after close

Electron can leave Postman.exe until you quit. That is not chrome.exe.

Alternatives

curl and Invoke-RestMethod for a terminal. VS Code REST Client for .http files. Insomnia is another API GUI.

Official help and downloads

Related hardware

The shell is Electron-class. Large collections want RAM. A GPU is irrelevant.
