Inspect
See the structure inside URLs and HTTP headers without sending the value anywhere.
When should you use an inspector?
Short answer: Use an inspector when you already have a URL or raw HTTP header block and need to confirm its structure, defaults, or security notes. Parsing happens locally in your browser.
Choose an inspector
Paste the raw value you have and get a readable breakdown.
What are the parsing rules based on?
URL structure follows the WHATWG URL Standard, while HTTP field semantics use HTTP Semantics as the reference. These sources let you verify the rules behind the output.
