Cómo usar

  1. 1Paste the expression or target URL on the first line, then add --- and the source document when the tool expects both.
  2. 2Load a sample first to learn the input shape, then replace it with your own JSON, XML, YAML, TOML, .env, robots.txt, sitemap, or headers.
  3. 3Review the matched values, warnings, duplicate keys, blocked paths, or security header notes before copying the result into docs or a PR.
  4. 4Keep the original source beside screenshots so teammates can reproduce the preview later.

Casos de uso

Debug API responses, XML feeds, deployment configs, SEO files, and HTTP responses without opening several separate tools.Validate AI-generated snippets before they become README examples, production configuration, or support answers.Create focused screenshots for issues, release notes, internal docs, and technical blog posts.

FAQ

Does this send my source to a backend or AI service?

No. These previewers run locally in the browser for the supported parsing path.

Is this a complete replacement for jq, Nginx, Google Search Console, or a production parser?

No. It is a fast preview and debugging surface for common cases. Keep the original tool or production runtime as the final authority.

Why does the input use --- in some tools?

It keeps the expression, URL, or comparison target separate from the document being inspected.

Parser de cabeceras HTTP is a focused preview utility for developers who need to inspect scripts, configuration, and structured data quickly.

It is especially useful after AI generation: generate the first draft, preview the behavior, fix obvious issues, then publish the source and screenshot together.

The first version covers common debugging cases and does not replace the original production parser for every edge case.

Demo: parse response headers for launch review

HTTP headers reveal cache, security, CORS, content type, and crawler behavior. A parser makes it easier to inspect a response before debugging in multiple tools.

  • Check cache-control beside CDN behavior.
  • Review CORS headers with the requesting origin in mind.
  • Confirm content-type matches the actual body.
HTTP/2 200
content-type: text/html; charset=utf-8
cache-control: public, max-age=3600
x-frame-options: DENY

Security checklist: headers are defense-in-depth

Header review should catch missing or contradictory security hints, but headers do not replace application security checks.

  • Use HSTS only after HTTPS is correct across subdomains.
  • Set CSP carefully to avoid breaking scripts and previews.
  • Avoid wildcard CORS with credentials.
strict-transport-security: max-age=31536000; includeSubDomains
access-control-allow-origin: https://app.example.com
