Even better, they don't charge for "products" such as wildcard certificates, but for the service of validation that is required to get them. This means you pay once for the validation (much less than a single wildcard certificate costs elsewhere) and then you can create certificates for all your domains at no additional cost. Obviously, they are a small CA, which means they are not recognised on some exotic platforms, but I haven't ran into any of those cases myself. Also, they require an intermediate certificate, but that was a no-brainer to setup. I have one up on my personal website, if you want to try if it works for you: https://micheljansen.org https://micheljansen.org
