CST VerdictBased on our analysis of available product data, here is our conclusion:
Frontend teams shipping third-party JavaScript or stylesheets will get the most from Subresource Integrity because it's the only native browser mechanism that catches CDN compromises and supply-chain tampering before code executes. A single cryptographic hash in your HTML tag stops malicious script injection cold, and it costs nothing to implement. Skip this if your threat model doesn't include compromised dependencies or if you're still loading unversioned assets from public CDNs without any integrity checks; SRI only works when you already control your resource URLs.
Fastify teams building token-based session architectures will find @fastify/csrf-protection valuable because it handles double-submit and signed-token patterns without the overhead of heavier middleware stacks. The plugin integrates directly into Fastify's request lifecycle, avoiding the configuration debt that slows adoption on smaller teams. Skip this if your API is purely stateless or you're already standardized on framework-agnostic CSRF libraries; at 168 GitHub stars, you're betting on a narrowly-scoped tool that won't evolve as fast as the broader Fastify ecosystem.
