Hi Product Hunt 👋 I'm the maker. This started the third time I found out a client's site had an expired certificate — from the client. Every registrar and host has its own reminder (or doesn't), and once you're minding dozens of domains across different providers, there's no single place to see what's about to lapse. SSLCanary fixes exactly that. Across ALL your domains, whatever the registrar or host, it watches two things: • SSL certificate expiry • Domain-name (registration) expiry …and warns you in plain English — "your SSL is fine / expiring in 7 days / broken" — before either lapses, on whatever you already use: email, Slack, Teams, Discord, Telegram, or a webhook. Add domains by pasting a list, a CSV/Excel, or a public Google Sheet, and group them by client. Built for the people who feel this most: agencies, freelancers minding client sites, small IT shops, and anyone sitting on a big domain portfolio. Try the free checkers right now — no signup. Paste a host, get an instant plain-English SSL verdict, or grab a free "SSL monitored" badge for your site: https://sslcanary.com/en/tools Built solo in Go (two tiny static binaries, SQLite — fully self-contained). I'd love your feedback, especially from folks juggling lots of domains: what do you use today to keep track? 🐤
