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. Mobile app security teams protecting Android apps from reverse engineering will find value in ELFcrypt's free binary obfuscation and anti-debugging combination, which addresses the specific gap most commercial mobile app protection tools leave open. The 127 GitHub stars and zero-cost model make it a pragmatic choice for teams with limited budgets who can tolerate manual integration into their build pipeline. Skip this if you need centralized policy management, compliance reporting, or support for iOS; ELFcrypt is a focused, developer-oriented tool that assumes you're comfortable maintaining it yourself.
