Free use and requirements

Use the local functions for free without a KitNelo account. Optional Gemini generation sends the supplied text to Google and requires a configured server API key; provider fees and quotas can apply.

The target must allow CORS. Requests time out after 30 seconds and responses are limited to 5 MB; sending can change the target service.

Test an HTTP Request in Your Browser for Free

Enter the request URL, method, headers and body, then send the request and inspect its response. The destination must permit CORS; review write methods carefully because sending a request can change data on the target service.

Import a cURL Request Online for Free

Paste a supported cURL command to populate editable HTTP request settings. Compare the imported method, URL, headers and payload with the original command before sending; unsupported shell options may need to be entered or handled separately.

Inspect HTTP Response Headers for Free

Send a browser request and examine the returned status, headers and response body to investigate an endpoint. CORS can hide response headers, requests stop after 30 seconds, and response content is limited to 5 MB.
