Certo — SSL cert auto-renewal for small fleets

Auto-renew and deploy 90-day free SSL certs across small site fleets

Problem

Indie devs and freelancers often run a dozen small sites on IIS or Nginx. Free certs from cloud providers have shrunk from one year to six months to three months; each renewal means request, download, import, bind. Sites slip past expiry, visitors hit red warnings, and sometimes the client notices first.

Solution

A lightweight panel that connects your sites, auto-issues and renews free certs via ACME, deploys them to IIS / Nginx / Apache through script templates, and retries plus alerts before expiry. Set it up once and forget it.

Users

Indie developers running multiple client sites, small web studios, part-time IT admins at SMBs

MVP

ACME auto-issue and renewal; deploy script templates for IIS, Nginx, Apache; multi-channel expiry and failure alerts; dashboard of all cert statuses; manual cert import as fallback

Revenue

Tiered subscription by number of sites (e.g. 10 / 30 / unlimited), annual discount; one-time desktop license as an alternative

Why now

Certificate lifetimes keep shrinking and cloud vendors won't manage across hosts for you; pure software, no licensing or ops team needed, buildable solo
