Channel Workbench: Stop leaking money from old YouTube links

Hey Product Hunt! 👋 Solo dev here. I built Channel Workbench after realizing my own old video descriptions were full of links that *looked* fine but earned nothing — dead amzn.to shortlinks silently redirecting to Amazon's homepage, product links missing their affiliate tag entirely, products that went out of stock years ago. Two decisions I made differently: 1. **Read-only YouTube access.** We literally cannot edit, upload, or post to your channel — the OAuth scope we request has no write permission. Your channel is your asset; we just audit it. 2. **No Amazon scraping, ever.** Stock and rating checks run through Amazon's official Creators API using your own free Associates credentials — so the affiliate account your income depends on is never at risk. You can try the free single-link checker with zero signup (paste any amzn.to and see where it really lands), or connect your channel for a free full-catalog scan with a revenue-at-risk estimate. Happy to answer anything about the compliance rabbit holes, the Blazor stack, or building this solo!
