A: No. Each developer writing code that uses DevExtreme needs their own named seat. However, build servers and CI/CD machines do not need a license.
: Because DevExtreme is a client-side library (JavaScript, React, Angular, Vue), the license key must technically be present in the browser to work. While this might seem like a security flaw, DevExpress treats these keys as "public" because they contain no private data; the real protection is the legal agreement (EULA) rather than technical obfuscation.
