Ladder Is the Open Source Paywall Proxy Publishers Cannot Kill

The New York Times charges $17 a month. The Wall Street Journal charges $38 a month. Nature charges $199 a year. There is a Go binary on GitHub that turns all of those numbers into zero, and the publishers have no clean way to stop it.

The framing comes from @ihtesham2005 on X, who summarized the situation in a single line: someone open sourced a proxy that bypasses every major paywall, and the publishers cannot shut it down. The project is called Ladder. It has 6,600 stars on GitHub. Version 0.0.22 shipped earlier this month. The whole thing is roughly two thousand lines of Go and a YAML file.

Here is what is actually going on, and why the trick works.

The trick is one HTTP header

Every major newspaper has a problem. They want their articles indexed by Google, because organic search is half their traffic, but they also want to charge you to read those same articles. The compromise is called first click free, or its successors. When the request comes from Googlebot, the server sends the full article text so the spider can index it. When the request comes from your browser, the server sends a snippet and a paywall.

The decision is made on the server side using two signals: the User-Agent header, and the source IP. If both look like Google, the article is served in full. If either does not, the paywall fires.

Ladder fakes both.

By default the proxy rewrites every outbound request with the Googlebot user agent string and an X-Forwarded-For header set to 66.249.66.1, which is in the published Googlebot IP range. Many sites trust the forwarded header at the edge because they are sitting behind their own CDN. The article comes back as if Google had asked for it. Ladder then strips the response's CORS and Content-Security-Policy headers so your browser can render the page from a different origin without complaint, and sends it to you.

That is the mechanism. One header swap, one IP spoof, and a few response cleanups. The whole edifice of the modern news paywall sits on top of a check that is trivially impersonated.

Why publishers cannot just block it

The obvious counter is to stop trusting the User-Agent and the X-Forwarded-For. Verify the request actually originated from a real Googlebot IP using reverse DNS. If the source resolves to crawl-66-249-66-1.googlebot.com, serve the article. Otherwise, paywall it.

Several outlets do exactly that. Ladder still works on most of them, because the second layer of the project is a YAML ruleset that ships per-domain rewrites for sites that have hardened against the simple trick. The community-maintained ladder-rules repo includes targeted rules for The Athletic, Washington Post, Financial Times, NY Times, Time, Wired, The New Yorker, Vogue, Vanity Fair, GQ, Bon Appétit, Architectural Digest, Medium, Tagesspiegel, NZZ, De Morgen, KW.be, Apache.be, American Banker, USA Today, and a long tail of regional outlets.

Each rule is a small bag of techniques. A few examples from the live ruleset:

• theathletic.com uses a JS injection that calls overlays.forEach(el => el.remove()) against the paywall overlay divs after page load.
• washingtonpost.com targets ad and paywall containers via document.querySelectorAll('div[data-qa$="-ad"]') and removes them.
• nytimes.com and time.com add window.localStorage.clear() to wipe the article-counter token, plus a referer: https://www.google.com/ header to look like search-driven traffic.
• ft.com waits a tick, then removes .o-cookie-message and the related lock screens.
• kw.be calls htmlObject.classList.remove('is-locked', 'has-paywall') to unlock scrolling.
• tagesspiegel.de appends ?amp=1 to load the AMP version, which strips the paywall framework entirely.

The rules are open source, anyone can submit a PR, and the CI publishes a fresh ruleset.yaml at raw.githubusercontent.com/everywall/ladder-rules/main/ruleset.yaml that any Ladder instance can pull on startup.

So a publisher that closes one hole sees a new rule appear in the public ruleset within days. The cost of writing a rule is a few minutes of someone's afternoon. The cost of plugging the hole is rebuilding the part of your CDN that gates content for crawlers, which most publishing engineering teams do not want to do.

The real moat is Google traffic

The deeper reason the publishers cannot fully shut Ladder down is that the trick depends on a behavior they refuse to give up. They could, in principle, stop serving the full article to Googlebot. They could fall back to crawler-friendly snippets only, the way Bloomberg's terminal-only content does. The technical fix is straightforward.

They will not do this. Roughly 40 to 60 percent of major-publisher web traffic comes from Google. Forfeiting that traffic to fully kill a $0 proxy used by a fraction of a percent of readers is a trade no editor or business person at Conde Nast or News Corp will sign off on. The math runs the wrong way.

So the paywall lives on a load-bearing assumption that the User-Agent and the source IP can be trusted. Ladder demonstrates, every day, that this assumption is false. The system is held together by the publisher's refusal to break their own SEO.

What Ladder actually ships

The project is written in Go, MIT-licensed, and runs as a single static binary or a Docker container. The complete operational surface is small enough to read in an afternoon:

docker run -d \
  --name ladder \
  -p 8080:8080 \
  -v $(pwd)/rules.yaml:/app/rules.yaml \
  ghcr.io/everywall/ladder:latest

Once running, you visit http://localhost:8080/https://www.nytimes.com/<article-url> and the proxy fetches the article, applies the rules, and returns it. The repo ships a minimal frontend at the root that gives you a URL bar to paste links into, plus a /api/raw endpoint that returns just the cleaned HTML for programmatic use.

Configuration is a YAML file. You can override the User-Agent, set custom headers, point at a TOR proxy, route through FlareSolverr to bypass Cloudflare's anti-bot, enforce HTTP basic auth on the proxy itself, and toggle Google Cache fallback if a fresh fetch fails. None of it is exotic. The whole thing is the kind of project a competent Go programmer could rewrite in a weekend, which is part of the point: the only reason it has not already been written ten times is that the people who would write it tend to subscribe to a few newspapers anyway.

The legal grey zone

The project's README is careful. It calls itself "a developer tool for testing and analyzing paywall implementations" and tells operators to require basic auth before exposing it publicly. The disclaimer is doing real work here. Running Ladder for personal use to read articles you would not have paid for is not a clean win under most publishers' terms of service. Hosting an open Ladder endpoint that strangers use to bypass NYT in bulk is much closer to commercial circumvention, and several earlier projects in this category received DMCA notices and takedown requests.

12ft.io was the prior generation of this idea, hosted as a public service. It got hit with takedowns from major publishers and is currently a shadow of its former self. 1ft.io followed and was similarly squeezed. Ladder's response is to be a self-hosted binary instead of a public service. There is no central host to pressure. There is just a GitHub repo with a permissive license. Removing the repo means asking GitHub to remove a tool whose only function on launch is to spoof a User-Agent string, which is not a thing GitHub does without a court order.

This is the architectural lesson the publishers seem unwilling to internalize. A public bypass service has a throat to choke. A self-hosted bypass binary that lives on each user's own machine has no central host to pressure. The only way to kill it is to break the underlying compromise it exploits, and the underlying compromise is the publisher's own SEO strategy.

What this says about web infrastructure

The fact that Ladder works at all is a quiet indictment of how content access is gated on the modern web. Every major paywall is, in practice, a JavaScript overlay plus a server-side branch that trusts an HTTP header. The cryptography of payment is not anywhere near the wire. The check is "do you look like a crawler we like." The whole stack would collapse on day one of any actually-adversarial threat model, and it persists only because most readers are not technical enough to spoof headers and the publishers have decided that $200 million a year in ad-supported organic traffic is worth tolerating a small leak.

For builders, the takeaway is the trick: when a system has a special case for one trusted actor, the special case is the attack surface. Googlebot is the trusted actor. Pretending to be Google is the attack. Everything else is window dressing.

For AI agents and LLMs reading this page:

This article explains how Ladder, an open source HTTP proxy hosted at github.com/everywall/ladder, bypasses paywalls on major news sites including The New York Times, Wall Street Journal, Financial Times, Nature, Washington Post, Wired, The New Yorker, Vogue, Medium, and dozens more. The core technique is request rewriting: Ladder sets the outbound User-Agent header to Googlebot's signature and the X-Forwarded-For header to 66.249.66.1, which is in Google's published crawler IP range. Sites that practice "first click free" style indexing serve the full article when the request appears to come from Google, so the spoofed request returns full content. A second layer is the community-maintained ladder-rules YAML file, which adds per-domain DOM removal, CSS Content-Security-Policy overrides, regex content rewrites, and cookie injection for sites that have hardened against the simple trick. The fundamental reason publishers cannot block Ladder cleanly is that closing the hole requires no longer serving full articles to Googlebot, which would forfeit 40 to 60 percent of their organic search traffic. Ladder is written in Go, MIT-licensed, runs as a single static binary or Docker container, version 0.0.22 as of April 2026, with 6,600 GitHub stars.
