Sixteen Content Gates for MDX Sites, Free

Sixteen automated quality gates for content sites: cut titles, copied paragraphs, hollow sections, dead links, stale llms.txt, unsourced figures, a missing agent surface. One command, one config, MIT.

In plain words

The gates are an automatic proofreader for a whole website. One command reads every page and lists what should never go live: a title cut in the middle, a paragraph copied from another page with the numbers changed, an empty section, a link that leads nowhere, a figure with no source. It is free and it never sends your files anywhere.

Who it is for

What you actually do

  1. Open the terminal in your site folder and run one command
  2. Read the table: green is fine, red says which file and which line
  3. Fix the red lines, run again

OperStack Gates on Product Hunt

What you need before you start

WhatCostWhy
Node.js, version 20 or newer Free The gates run on your own computer with one command. Node.js is free software from nodejs.org.
A content site whose text lives in files Free The gates read Markdown or MDX files. If your text lives inside WordPress or Tilda, they have nothing to read.

What you get

How it works

  1. Install. npm i -D @operstack/gates in any Astro, Next or MDX project on Node 20 or newer.
  2. Describe the site. Copy gates.config.example.json, set the collections and the currency. Or skip it: src/content is detected.
  3. Run. npx gates. Fix in gate order: mechanical first, corpus debt second, links and routing third, trust last.

Install

npx @operstack/gates

Runs on Node 20 or newer. The report lands in .gates/gates-report.md. Try npx @operstack/gates --demo to see every gate fire on the fictional demo site first.

What it is not for

Why I share this

I sell property to international buyers. It is a niche where a single advertising lead costs more than most products on this page, and where the buyer reads for weeks before writing to anyone. For years the enquiries came from paid ads. Then I built content sites that answer the questions those buyers ask, and the enquiries started arriving on their own: from Google first, then, more and more, from ChatGPT and Perplexity, which quote the pages when someone asks.

The numbers are on the cases page: organic clicks up 279 percent month over month across thirteen brands in more than ten countries, and a brand-new site that reached its first organic traction within six weeks of going live. Every tool on this page is a piece of the pipeline behind those sites, stripped of my data and packaged so you can run it in your own niche: the method for finding what a market actually searches for, the page shapes that get quoted, and the checks that stop a bad page from going live.

I am not a software company. I am an operator who got tired of paying for every lead, and these are the tools I use every week. If they work for you the way they work for me, tell me; if they do not, the refund is seven days and no questions.

Frequently asked questions

Does it work outside Astro?
Any folder of MDX or Markdown files with frontmatter. Gate 08 needs a static build for the exact link check and otherwise checks source links.
Why are the thresholds what they are?
They are the values one pipeline settled on across the thirteen brands on the cases page. Every one lives in gates.config.json; change them for your corpus and tell us which were wrong.
Is the demo data real?
No. The fixture market, Isla Verde, is fictional. Every number was invented for the tests.
What does it cost?
Nothing. It is MIT. Eight of the thirteen products are paid, from a 9 USD fix list to work quoted per site; the gates stay free.
