SSL Certificate Expiry Watchbot

Derivation Chain

Step 1 Manjaro site down due to certificate expiry
→
Step 2 Website certificate management automation
→
Step 3 Certificate expiry early-warning + auto-renewal tool

Problem

Small-to-mid web agencies and SaaS operations teams managing 10–100 domains manually track SSL/TLS certificate expiration dates. Missing even one certificate results in site inaccessibility, causing an average of 2–6 hours of downtime. The resulting revenue loss ($750–$7,500 per hour) and erosion of customer trust far exceeds the cost of the certificates themselves—often by hundreds of times.

Solution

Users register their domain list and receive staged expiry alerts at D-30/D-7/D-1 via Slack, email, or KakaoTalk. Domains using Let's Encrypt support one-click automatic renewal. Core features: (1) Multi-domain certificate status dashboard, (2) Staged expiry alerts (Slack/KakaoTalk/email), (3) ACME protocol-based automatic renewal trigger.

Target: Web agencies managing 10–100 domains (5–30 employees), DevOps leads at SaaS Startups operating multiple services
Revenue Model: Freemium: Free up to 5 domains, 6–50 domains at $22/mo (~29,000 KRW), 51–200 domains at $59/mo (~79,000 KRW), auto-renewal add-on $7.50/mo (~10,000 KRW)
