The pitch
Claude
A drop-in reverse-proxy for self-hosted sites that fingerprints AI-training crawlers by UA+ASN, blocks them by default, and emails a weekly report of blocked requests and bandwidth saved.
Who it's for: Independent publishers, forum operators, and self-hosted content sites (like the HN poster whose site is 99% bot traffic) who currently maintain manual .htaccess/nginx UA blocklists or rely on static community lists like ai.robots.txt that go stale within weeks.
The problem: time (constant manual updating of crawler signatures as UAs/IPs rotate) and payment (bandwidth/hosting cost inflated by scraper traffic)
How to build it: Single Docker sidecar or nginx/Caddy config module that sits in front of the origin, plus a small dashboard/weekly email report; installed via one config include line, no CDN migration required
How it makes money: Site owners with measurable bandwidth cost from scraping pay $15-40/mo for a maintained, auto-updating signature database and weekly report, because the free static blocklist doesn't self-update and manually chasing new crawler UAs costs more engineer time than the subscription
Why it doesn't exist yet: Cloudflare/Fastly bundle bot mitigation as a CDN upsell, so sites not on those CDNs (custom stacks, on-prem, compliance-locked) get nothing; the community workaround (ai.robots.txt) is a static text file that nobody automates or version-tracks, so it silently rots
First users: Direct outreach to authors of 'fighting scrapers' posts (like patronview.com) and self-hosted forum/blog communities (NodeBB, Discourse, WordPress self-host groups) already complaining about this exact pain this week
Build size: 2 people x 10 weeks - includes: nginx/Caddy middleware generator, weekly-updated crawler signature database, dashboard + email report; excludes: JS-challenge/CAPTCHA browser fingerprinting and full CDN replacement
Biggest risk: Cloudflare or Fastly rolls their existing AI-crawler-block toggle into the free tier broadly (already partly true for CF customers), removing the reason to install a standalone tool
Conditions for a hit (all 3 required):
- Blocks requests matching known AI-crawler UA strings (GPTBot, ClaudeBot, CCBot, Bytespider, PerplexityBot) and associated ASN ranges with a 403, verifiable by curling the origin with those UAs
- Sends a weekly email/dashboard report showing count of blocked requests and estimated bytes saved, generated from proxy access logs
- Ships a versioned signature database with a public changelog updated at least weekly
How it's judged (in 6 months): Product Hunt daily top 5, or GitHub repo with 300+ stars, or public case study of 10+ paying customers at $15+/mo(judgment date 2027-02-08)
AI self-confidence 42/100 — self-reported likelihood of meeting the criterion, not a business success rate
Exclusions ▾
- General CAPTCHA/browser-fingerprint bot mitigation like Cloudflare Bot Fight Mode does not count as a match
- Pay-per-crawl licensing marketplaces (TollBit-style monetization for AI companies) do not count as a match
