The problem
Free certificates from Let's Encrypt last 90 days. Renewing them usually means installing and babysitting tools on every server, and one missed renewal takes a site offline, often at the worst moment. Most monitoring only speaks up after something is already wrong.
Our judgment
- 01
Validate without touching the server
Ownership is proven with one DNS TXT record, so nothing is installed on the customer's servers, and wildcards work the same way.
- 02
Renew early, watch everything
Renewals start well before expiry. Monitoring covers any domain, wherever its certificate came from, with alerts to email, Slack, Discord and webhooks.
- 03
Open it to agents
An MCP server with OAuth sign-in lets Claude and other assistants request, renew and inspect certificates in conversation.
In production
Screens from the running products, with example data.
Results
- $0
- for a certificate on every plan, wildcards included.
- 1
- DNS record to prove ownership. Nothing to install on the server.
- MCP
- server, so AI assistants can issue and inspect certificates.
How it is built
Free, wildcards included
Certificates cost nothing on every plan. Issuance is never the upsell.
One DNS record
Add the single TXT record the page asks for. No agents to install on your server.
Automatic renewal
A renewal starts well before expiry, so a certificate never lapses on a weekend.
Monitoring for any domain
Watch expiry and TLS configuration for domains wherever their certificates came from.
Alerts where you work
Email, Slack, Discord and webhooks, before anything turns red.
An MCP server
Connect Claude or another assistant and issue or inspect certificates in conversation.
