Sperone is free to run. There is nothing to install or activate — download it and go. Licensing is honor-based: the server never refuses to serve.
A commercial license is required to use Sperone for business. It is a portable key you install on your server; it removes nothing technical — it makes your use licensed.
Pay with card on Stripe. The signed key is saved to your account to download and re-download.
