FAQ
Why do some requests timeout?
The timeout is 30 seconds by default. If upstream is slow or unreachable, a timeout message will be returned.
Can I send body with GET?
Technically possible in some cases, but generally not recommended. Prefer query parameters for GET requests.
Is history uploaded to server?
No. History is stored only in local browser storage and limited to 20 records.
