Practical • Static-first • Security-focused

Build a cleaner CSP workflow without guessing.

This site brings together a CSP generator, header audit tools, and implementation guides for teams shipping static sites, Jamstack apps, and frontend-heavy platforms.

  • No backend required for the site itself
  • Useful for Next.js, Shopify, and Cloudflare Pages
  • Start with report-only, then tighten safely
Static security workflow
Live

01 / Start with the task

Choose whether you need to generate a policy, inspect real headers, or understand a platform-specific setup.

02 / Keep the flow simple

Generate first, validate with checkers, and use the guide or FAQ only when you need context.

Tools Guide FAQ

AI can summarize the theory, but this site helps you verify the live header.

Use the articles to understand the pattern, then jump into the tools when you need a real answer from a real page.

The fastest path is always: generate, check, compare, and only then enforce.

Start with the two jobs that matter most

The homepage stays focused on getting people to the right tool fast.

Explanations live deeper in the guide and FAQ, not in the hero.

CSP Generator

Build a copy-ready policy string with report-only, nonce, hash, and common directive helpers.

Generate a policy

Security Headers Checker

Paste response headers and quickly see what is missing, why it matters, and how to fix it.

Audit pasted headers

CSP Checker

Fetch real response headers through a proxy or paste them manually to inspect CSP coverage.

Check a live URL

CSP Hash Generator

Compute sha256-… hashes for inline scripts or stylesheets before pasting them into your policy.

Hash a script

CSP Evaluator

Score a Content-Security-Policy header from 0 to 100 with explanations of every risk.

Score a policy

CSP Diff

Compare two policies directive-by-directive to see what changed between report-only and enforce.

Compare two policies

Cookie Security Checker

Audit Set-Cookie headers for Secure, HttpOnly, SameSite, and the __Host- / __Secure- prefixes.

Audit cookies

CSP Bypass Lab

Run your HTML under your CSP in a sandboxed iframe and see which payloads are blocked.

Open the sandbox

Permissions-Policy Helper

Pick the browser features your site uses and emit a copy-ready Permissions-Policy header.

Build a Permissions-Policy

SRI Hash Generator

Compute integrity hashes for any external <script> or <link> so CDN tampering is detectable.

Hash a CDN script

Cross-Origin Headers Visualizer

Understand COOP, COEP, CORP, and OAC — and one-click the config that unlocks SharedArrayBuffer.

See the headers

Meta Tag & OpenGraph Inspector

Spot missing og:, twitter:, viewport, canonical, and theme-color on any URL or pasted HTML.

Inspect meta tags

robots.txt Generator & Tester

Edit a robots.txt visually and immediately check whether a URL would be allowed or blocked.

Generate & test

sitemap.xml Validator

Validate any sitemap for required fields, http/https consistency, long URLs, and 50K cap.

Validate a sitemap

JSON-LD / Schema.org Validator

Detect Schema.org types, check required fields, and surface common structured-data errors.

Validate JSON-LD

Email Auth (SPF / DKIM / DMARC)

Inspect a domain's SPF, DKIM, and DMARC records via DNS-over-HTTPS — no backend required.

Check email auth

Redirect Chain Visualizer

Follow every hop in a redirect chain, see status codes and timings, and catch loops.

Trace redirects

Why this site is structured this way

Each section has a job: conversion, explanation, or troubleshooting.

1. Clear value up front

The first screen explains what the toolkit does and where to begin.

2. Low-friction entry points

The core tools stay visible so users do not have to interpret a large docs-first homepage.

3. Search-friendly support

Guides and FAQs handle concepts, platform details, and recurring implementation questions.
