Postman alternative

Looking for a Postman alternative? HITOP is an open source API testing tool built around privacy. It needs no account, and its Mac, iOS and CLI apps work offline.

Why look for a Postman alternative?

While Postman is a popular API testing tool, many developers are seeking alternatives due to concerns about privacy, mandatory account requirements, and the shift toward cloud features. HITOP offers a compelling alternative for developers who value privacy and simplicity.

Key difference: privacy first

HITOP stores all your data locally on your device. No cloud sync, no account, no data collection. Your API endpoints, authentication tokens and test data stay on your machine. The web app sends requests to public APIs through the HITOP request proxy, which keeps nothing; the Mac and iOS apps, the CLI and the extensions send them straight from your device.

Top reasons to switch from Postman to HITOP

1. No account registration

Start testing APIs immediately without creating an account, verifying email, or providing personal information. HITOP respects your privacy from the first click.

2. Complete privacy control

All your collections, requests, and variables are stored on your device. Nothing is synced to a cloud. For internal or sensitive APIs, use the Mac app, the CLI or an extension, which send requests straight from your machine.

3. Works offline

The HITOP Mac app, iOS app and CLI work with no internet connection. Test APIs on airplanes, in secure environments, or anywhere without connectivity. The web app needs a connection, because public requests go through the hitop.rws8.tech proxy.

4. Open source

The HITOP web app, extensions and CLI are open source under the MIT License. You can inspect the code, contribute features, or fork it for your own needs. Complete transparency.

5. Lightweight and fast

No bloated desktop application. The web app runs in your browser with a clean, responsive interface that doesn't slow down your workflow.

6. Works everywhere

The web app works on any operating system with a modern browser: Windows, macOS, Linux, ChromeOS. There are also Chrome and Firefox extensions, Mac and iOS apps, and a CLI.

What you get with HITOP

Migration from Postman

Switching from Postman to HITOP is straightforward:

  1. Export your Postman collections as JSON (Collection v2.1), and your environments and globals
  2. Open HITOP and use the Import feature, or run hitop import <files> --to ./my-api
  3. Your collections, requests, and variables are ready to use

The full steps, including secrets and scripts, are in Migrate from Postman.

Pro tip

HITOP supports Postman collection format, making migration seamless. You can even use both tools side by side during your transition.
