Compare features, ratings, integrations, and community reviews side by side to find the best runtime application self-protection fit for your security stack.
Based on our analysis of core features, here is our conclusion:
Fastify teams building APIs that need HTTP header security without operational overhead should start with @fastify/helmet; it's a thin wrapper around the battle-tested helmet library, meaning you get OWASP Top 10 mitigations (CSP, HSTS, X-Frame-Options) with minimal configuration beyond `fastify.register()`. The 453 GitHub stars and zero-friction npm install make adoption frictionless for small-to-mid teams. Skip this if you need dynamic policy management, request-level header mutation, or centralized policy enforcement across multiple services; @fastify/helmet is intentionally static and Fastify-bound, not a gateway or orchestration tool.
