QuietLeaks
Affiliate link health monitor — tracks every link, detects 404s and silent redirects, and tells you exactly how much money a broken link is costing you.
QuietLeaks is a live SaaS product built by Zwebist. It monitors affiliate links around the clock via a dedicated Node.js worker on Fly.io, follows full redirect chains (including JS-rendered redirects via Puppeteer), tracks every click through a first-party proxy, and calculates earnings at risk for every broken link. Built for bloggers, YouTubers, and content agencies.

The Challenge
Generic uptime monitors report a link as healthy if any hop returns 200 — even if a silent redirect has killed the affiliate tag. Affiliate links go through 3–5 redirect hops, some JavaScript-rendered. The product needed to understand the full chain, detect silent destination changes, and do this at scale without getting rate-limited by affiliate networks.
Our Solution
Dedicated Node.js worker on Fly.io consuming a BullMQ queue backed by Upstash Redis. Fetches with got-scraping for user-agent rotation, follows every redirect hop, falls back to Puppeteer for JS-rendered redirects. Full chain stored as JSONB. Click tracking via a first-party edge proxy for real earnings-at-risk data.
