Overview

Postman is a dedicated API client used to build, send, and test HTTP requests during API development, going well beyond simple request-response tools with features like collections, environments, scripted tests, and mock servers. It has effectively become a default tool for backend and API-focused development work.

It suits developers, QA engineers, and API teams who need to organize many requests, share them with teammates, and automate test assertions against responses. Its collaboration features — shared workspaces, version history, and team libraries — are aimed squarely at teams rather than solo scripting.

Compared to lighter alternatives like Insomnia, Postman offers a broader feature set (mock servers, monitors, extensive scripting via its Postman Sandbox) but at the cost of a heavier, more complex interface. Many of its advanced features, along with team collaboration, require a paid plan or signing in with a Postman account, whereas fully local, account-free usage is more limited than it once was.

For simple one-off API checks, a command-line tool like curl or a lighter GUI client is often faster; Postman earns its complexity on projects with many endpoints, environments, and team members who need a shared source of truth for API testing.

Key features

  • Build and organize HTTP requests into collections
  • Environment variables for switching between dev, staging, and production configs
  • Pre-request and post-response scripting with the Postman Sandbox
  • Automated test assertions on API responses
  • Mock servers for simulating APIs before the backend exists
  • Shared team workspaces with version history

System requirements

Operating system
Windows 11 and Windows 10 (64-bit); also available for macOS
Account
A Postman account is required for most features, including saving collections to the cloud

How to install Postman

  1. 1. Download the installer

    Get the Windows installer from postman.com/downloads.

  2. 2. Run setup

    Complete the installer with default options unless you need a custom install path.

  3. 3. Sign in or skip

    Sign in with a Postman account to sync collections, or use limited local-only functionality without one.

  4. 4. Import existing collections

    Import OpenAPI specs, curl commands, or existing Postman collection files to get started quickly.

How to use it

  1. 1. Create a collection

    Group related API requests into a collection so they're easy to find and share.

  2. 2. Use environments

    Store base URLs and secrets as environment variables to switch contexts without editing every request.

  3. 3. Write tests

    Add assertions in the Tests tab to automatically validate response status, body, and headers.

  4. 4. Automate with the Collection Runner

    Run an entire collection in sequence to test a full API workflow at once.

Safety and privacy

  • Download only from postman.com/downloads.
  • Be mindful that requests and collections saved with cloud sync are stored on Postman's servers unless you deliberately keep work local.
Bundled software
No third-party bundling in the official installer.
Privacy
Postman syncs collections, environments, and history to your account by default when signed in; review workspace visibility settings before storing sensitive tokens or API keys in shared collections.

Known risks

  • Storing API keys or secrets directly in collections that get shared with a team can leak credentials if workspace permissions aren't set carefully.
  • Mock servers and monitors are cloud features, so they depend on Postman's infrastructure being reachable.

What's new

  • Current release

    Postman updates frequently, both the desktop app and its cloud-connected features. Check the in-app updater or Postman's changelog for what's new in your installed version.

Pros and cons

Pros

  • Comprehensive feature set covering requests, testing, mocking, and documentation
  • Strong team collaboration and shared workspace tools
  • Widely used, so onboarding help and examples are easy to find
  • Supports REST, GraphQL, WebSocket, and gRPC-style testing

Cons

  • Interface can feel heavy for simple one-off requests
  • Many features require signing in or a paid plan
  • Cloud sync means some data leaves your local machine by default
  • Steeper learning curve than minimal API clients

Verdict

Postman is a strong choice for teams building and testing APIs collaboratively, with more built-in functionality than most competitors. Individual developers who just need to poke at an endpoint occasionally may find a lighter tool faster to use.

Frequently asked questions

Is Postman free?

Yes, there's a free tier, but it requires a Postman account for most features and has usage limits; team and higher-usage features require a paid plan.

Do I need an account to use Postman?

You can use limited functionality without signing in, but syncing collections, team workspaces, and several other features require a Postman account.

Does Postman run on Windows 11?

Yes, Windows 11 and Windows 10 (64-bit) are both supported.

How is Postman different from Insomnia?

Postman offers a broader feature set including mock servers and monitors, while Insomnia is generally lighter weight and has historically offered more functionality without requiring an account.
