Purpose

I designed this domain and certificate manager because I had so many different subdomains and I use letsencrypt certificates to secure all of those domains and subdomains. While command-line tools exist for these tasks, I wanted a unified UI to visualize and manage everything from a bird’s-eye view.

Key Features

• Dynamic DNS (DDNS): Automatically checks your public IP and updates DNS records if they change.
• SSL Management: Wraps Certbot to handle creation and renewal of certificates using the DNS-01 challenge (Wildcard supported).
• Web Dashboard: A clean, responsive UI to view the status of all your domains at a glance.
• Settings UI: Configure domains, notifications, timezones, and log retention directly from the browser.
• Notifications: Get alerts via Discord, Slack, Telegram, Email (SMTP), and more.
• Mobile Friendly: Fully responsive design.

Important Notes

1. SSL Lifecycle: This app manages the full lifecycle of certificates. It can only renew certs it created. Existing certs should be replaced by ones generated here for auto-renewal.
2. Authentication: This app has no built authentication. If you choose to expose this to the internet, it is strongly, strongly, super strongly recommended to protect your instance using a reverse proxy and authentication service (e.g., Nginx and Authentik).
