Best No-Restriction Alternative to Requestly

Relay (Chrome Extension)

Relay is an open-source browser extension that lets you intercept and modify HTTP requests directly inside your browser. It doesn’t require an account or paid plan.

Why it’s the best unrestricted alternative

No login required

Open source

No rule limits

Works directly in the browser

Free

You install it and start intercepting requests immediately.

Main Features

Intercept HTTP requests

Relay can capture requests made by websites and APIs.

You can see:

headers

request body

parameters

response data

This helps debug frontend apps and APIs.

Modify requests

You can edit requests before they are sent.

Examples:

Change Authorization headers

Modify POST body

Add or remove headers

Change query parameters

This is useful for testing APIs or bypassing certain checks during development.

Run API requests directly in the browser

Relay can send requests manually like a mini Postman inside Chrome.

You can:

run REST requests

test endpoints

export requests as cURL commands.

Save and organize sessions

Relay lets you save request sessions so you can reuse them later for debugging or testing.

When Relay is best

Relay is ideal if you want something:
