CST VerdictShort answer
Developers building APIs and web services need bot and rate-limit protection that doesn't require security expertise to deploy, and Arcjet's SDK-first approach means you configure rules in code rather than wrestling with WAF consoles. The WebAssembly-based local execution runs decisions at the edge without sending traffic to external services, cutting latency and keeping you compliant with data residency constraints. Skip this if your primary concern is legacy OWASP Top 10 coverage on existing monolithic applications; Arcjet is built for modern application stacks, not retrofitting old infrastructure. Frontend developers and security teams protecting user-facing applications from XSS will find DOMPurify essential because it strips malicious scripts from HTML without breaking legitimate functionality, something most sanitizers fail at consistently. With 16,746 GitHub stars and active maintenance across thousands of production deployments, the library has been battle-tested against real XSS vectors that OWASP regularly updates. Skip this if your threat model requires server-side output encoding as your primary defense; DOMPurify is client-side hygiene, not a replacement for secure coding practices upstream.
