## What it is
A NodeJS library that automatically obtains and renews free SSL/TLS certificates from Let's Encrypt using SNI, with near-zero configuration. It creates an HTTPS server (compatible with Express, Koa, etc.) and forwards incoming HTTP requests to HTTPS.

## Use cases
- serve a nodejs site over https with free letsencrypt certificates
- automatically renew ssl certificates for a node app
- redirect all http traffic to https in nodejs
- add tls to an express app without manual certificate management
- set up https with zero configuration for multiple domains

## When to choose
- you want free automated Let's Encrypt certificates in a NodeJS server with minimal setup
- you need automatic certificate renewal and HTTP-to-HTTPS forwarding in one package

## When to avoid
- you need a maintained library - the project is explicitly no longer maintained
- you're on modern NodeJS where built-in ACME tooling or alternatives like Greenlock or Certbot may be better supported

## Facets
- artifact type: library
- maturity: abandoned

- domain: web-development, backend, security, self-hosted
