Why teams choose ExisOne
- Predictable cost. One flat monthly price with no per-activation metering or overage bills, no matter how often your customers activate or validate.
- Fast to integrate. Three lines of code with a native SDK for .NET, Python, Node.js, or Swift — or call the REST API directly from any language.
- Payments built in. Connect Stripe or PayPal and license keys are generated and emailed automatically the moment a customer pays.
- Works offline. RSA-SHA256 signed activation codes keep air-gapped and disconnected installs licensed.
