URL Parser

Parse URL components and query parameters online for debugging and API troubleshooting.

What this tool does

Parse a full URL into protocol, host, subdomain, port, path, query string, fragment, and query parameter rows. This is useful for callback URL debugging, request tracing, integration troubleshooting, and analytics link verification.

Tool interface

Parse URL Components

Parse a URL into protocol, host, subdomain, port, path, query string, fragment, and query parameter rows.

Example input

https://api.example.com:8443/v1/orders/42?expand=items&include=payments&env=staging#response

Example output

{
  "protocol": "https:",
  "host": "api.example.com:8443",
  "subdomain": "api",
  "port": "8443",
  "path": "/v1/orders/42",
  "queryString": "?expand=items&include=payments&env=staging",
  "fragment": "#response"
}

Step-by-step instructions

  1. Paste an absolute URL with protocol (for example `https://...`).
  2. Run URL parsing to extract structured components.
  3. Review query parameters in key/value rows.
  4. Copy parsed JSON output when you need to share or log analysis.
  5. Use URL encoder/decoder tools for follow-up cleanup if needed.

Common use cases

  • Inspecting callback URLs during OAuth and webhook integration.
  • Debugging tracking links and query parameters.
  • Breaking down redirect URLs to verify host and path values.

Makes complex URLs easier to inspect when debugging redirects, OAuth callbacks, webhooks, and tracked API requests.

Common mistakes to avoid

  • Pasting relative URLs without a protocol.
  • Assuming duplicate query keys map to a single value.
  • Forgetting percent-decoding when inspecting encoded parameters.

Does this include subdomain and port parsing?

Yes. Subdomain and port are extracted into separate fields.

Are relative URLs supported?

No. Use a full absolute URL including protocol.

How are repeated query keys handled?

Repeated keys are listed as separate key/value rows so duplicates remain visible.

Can I copy parsed output?

Yes. You can copy parsed JSON output for logs, tickets, or debugging notes.
