Is it private and secure?

Your privacy is built in. Postman Collection Viewer runs completely on your device, so whatever you enter stays in your browser and is never transmitted, logged or stored on any server.

Network activity: none. Nothing is sent and nothing is fetched. This tool makes no network request at all once the page has loaded — which is why it keeps working if your connection drops.

You do not have to take that on trust — our privacy proof page publishes the Content-Security-Policy that enforces it, lists every third party it permits, and shows how to verify the whole claim yourself.

Frequently asked questions

How do I view a Postman collection without installing Postman?

Export the collection as JSON from Postman (Collection → Export → v2.1) and open the file here. Every request, method, URL, header and body is laid out as a readable tree, which is often all you need when reviewing someone else's collection.

Is it safe to open a collection that contains secrets?

The file is parsed in your browser and never uploaded, so nothing is transmitted. That said, exported collections frequently embed API keys and bearer tokens in headers or variables — worth remembering wherever you store the file itself.

Which collection format versions are supported?

Postman Collection v2 and v2.1, the formats current Postman exports produce. The much older v1 format has a different structure and should be converted in Postman first.

Can I see the environment variables a request uses?

Variable placeholders such as {{baseUrl}} are shown exactly as written in the collection. Their values live in a separate environment export, which Postman does not include in the collection file.
