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. Development teams protecting Java and PHP applications from injection attacks and data exfiltration will get the most from OpenRASP because it instruments application code directly rather than relying on network signatures that miss context-aware exploits. The 2,956 GitHub stars and active community reflect real adoption in production environments where developers can see exactly which requests trigger blocking rules. Skip this if you need mobile app protection on iOS or Android; OpenRASP focuses on server-side application security and won't help you secure client-side code.
