Frequently Asked Questions
Is this a Postman alternative?
Yes! ByteKit HTTP Request Builder lets you send API requests directly from your browser without installing any software. It supports all HTTP methods, custom headers, and JSON bodies.
Why might some requests fail?
Requests to APIs that don't allow cross-origin requests (CORS) will fail in the browser. This is a browser security restriction — use a CORS proxy or server-side tool for those APIs.
Are my requests logged?
No — your requests go directly from your browser to the API. ByteKit never sees your request data, headers, or API keys.
What is the cURL tab?
ByteKit generates the equivalent cURL command for your request so you can run it in your terminal or share it with teammates.
