Best Postman Interceptor Alternatives in 2026
Postman Interceptor captures browser requests and cookies into Postman. People look for alternatives when they need to modify traffic rather than just capture it, want to avoid the desktop app, or need to share interception rules with a team.
ProxyCeptor
A DevTools Network tab with HAR export for capture, plus rules that mock, deep-merge, delay, block and redirect requests. Includes Commander, a browser-based API client.
Chrome DevTools (built in)
"Copy as cURL" or "Copy as fetch" from the Network panel, HAR export, and Local Overrides for simple response edits.
Requestly
Open-source extension and desktop app with redirect, header and mock rules and an API client.
HTTP Toolkit
Captures traffic from browsers, Android and backend processes with automated certificate setup.
EchoAPI Interceptor
A Chrome extension for one-click request capture into the EchoAPI client, with no login required.
Frequently asked questions
Why is Postman Interceptor not capturing requests?
Common causes are that the Postman app is not running or not connected to the extension, the capture filter excludes the domain, or the requests come from a service worker. Check the connection status in both the extension and Postman.
Can I capture requests without Postman?
Yes. Chrome DevTools and ProxyCeptor both capture and export HAR, and ProxyCeptor can modify the captured requests with rules.
