InjectionWitness

Reasons to doubt this
AI cross-check (GPT)
Cookiebot and OneTrust both offer ongoing/periodic website scanning that detects new cookies and scripts after deployment (e.g., Cookiebot’s continuous website scanning and OneTrust’s Continuous Cookie Scan), so it’s incorrect to say they only scan at deploy time and won’t detect later injections.
AI cross-check = a peer model flags a logic issue. Editorial fact-check = a web-sourced correction. The card text is never rewritten; corrections sit beside it.
The pitch
Claude
For site owners who moved DNS/CDN providers, nightly-diffs their live HTTP response against an approved script/cookie allowlist and alerts within 24h the first time a host silently injects a new tracker or cookie.
Who it's for
EU-based agencies and SMBs running self-hosted or CDN-fronted sites (Cloudflare, Fastly, Netlify) who today only catch surprise injections via manual 'view source' spot-checks or a stranger's HN thread.
The problem
legal: GDPR/ePrivacy exposure when a hosting/CDN layer injects tracking cookies or analytics without the site owner's knowledge, leaving the owner liable for consent they never obtained.
How to build it
Web dashboard: user submits URLs plus an allowlist of expected script domains/cookie names; a headless-browser crawler runs nightly, diffs the response against the last approved baseline, and posts Slack/email alerts with the exact new line.
How it makes money
Agencies and SMBs with GDPR-liable sites pay $15-30/month per domain for continuous monitoring plus a dated compliance evidence export, because a manual view-source check doesn't run daily and produces no proof for a data-protection-authority inquiry.
Why it doesn't exist yet
Cookie-consent vendors (OneTrust, Cookiebot) scan at deploy time for cookies you declared, not for injections introduced later by the DNS/CDN layer itself, and have no incentive to flag their hosting partners' own behavior; an indie tool has no such conflict of interest.
First users
Post directly into the same HN thread and indie-hacker/webmaster forums reacting to the Cloudflare nameserver-injection story; agencies managing multiple client sites want proof they didn't cause the leak.
Build size
2 people x 8 weeks: crawler+diff engine, allowlist config UI, Slack/email alerting, PDF/CSV evidence export; excludes cookie-consent-banner management and WAF-style blocking.
Biggest risk
A major CDN (e.g. Cloudflare) ships a public per-zone transparency log of every script/header it injects, making third-party injection audits redundant.
Conditions for a hit (all 3 required)
- Nightly headless crawl of each submitted URL compares live response bytes to the last approved baseline and lists any new <script src> domain within 24h
- Flags any new Set-Cookie header/domain not present in the user's allowlist, showing the exact cookie name and source domain
- Generates a dated PDF/CSV evidence log of every detected change, downloadable per domain per month

Exclusions ▾
- Cookie-consent banner/CMP tools that manage user consent choices are not a match
- General uptime/broken-link monitors without script or cookie diffing are not a match
