Features, pricing, ratings, and pros & cons — compared head-to-head.
Hapi is a free api security tool. Impart WAF is a commercial api security tool by Impart Security. Compare features, ratings, integrations, and community reviews side by side to find the best api security fit for your security stack.
CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Node.js teams building APIs from scratch will find Hapi's security-by-default architecture saves months of hardening work; its plugin system lets you bake authentication, validation, and CORS rules into the framework itself rather than bolting them on afterward. With 14,784 GitHub stars and active maintenance, you're not betting on a ghost project. Skip Hapi if your team is already committed to Express or Fastify; switching frameworks mid-project costs more than the security gains justify.
Teams shipping APIs at startup speed need Impart WAF because its AssemblyScript rules and Terraform integration let developers write and test WAF policy the same way they write application code, eliminating the security-ops bottleneck that kills deployment velocity. The runtime rule graphs and automatic false positive detection reduce alert fatigue by half compared to signature-based WAF, and JWT-plus-API-key authorization analysis catches account takeover attempts that simpler tools miss entirely. Skip this if your org still uses WAF primarily for perimeter defense against script kiddies; Impart is built for teams defending APIs and microservices that move faster than traditional security workflows allow.
