Show HN: Certera – A central validation server for Let's Encrypt certificates

Certera is a central validation server for Let's Encrypt certificates. It's a cross platform, self-hosted web application. With Certera, you can centralize all of your LE certificates and keys, monitor certificates and receive notifications for cert changes and expirations. It will also help you stay within LE quota limits. Check out the docs for more details and screenshots. It's currently in beta as I'm looking for folks to start using and provide some feedback.

I created this because I had been using various ACME clients and occasionally a change here and there could cause things to break. Or, a cert would be on a system that I didn't know about and the cert would expire without anyone knowing about it. The biggest driver was making it simpler to use LE certs behind load balancers since Certera separates acquiring certificates and applying them. The idea is that you use Certera to acquire certificates, then use the API provided to retrieve the certs and keys to apply them. Currently, it only works with HTTP-01 validation (and redirects). I'm planning on adding DNS-01 validation and some hooks to make certificate automation much better when it comes to client certificates (i.e. rotating SSO certificates or certificates used for securing endpoints).

I struggled a lot with the licensing and settled on something that's not "open source"; it's source available. It is free for personal use, nonprofits and small organizations (< $1M in revenue). It's free for all during the beta. 10% of all revenue will be shared back to projects used to build Certera, the breakdown is in the docs.

Some principles I've tried to follow while building this: - Perpetual license only. I'm kind of burned out with subscriptions. - The least amount of Javascript I could get away with. There are no frameworks. All in all, less than 10 lines of plain vanilla JS.

Thanks for reading and let me know what you think!
