Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

ESLint

  • Slow performance on large codebases compared to newer tools like Oxlint and Biome
  • Complexity in configuration from scratch, particularly for TypeScript support
  • Limited built-in TypeScript support, requiring separate parsers and coordination with new TypeScript features

Fortinet FortiGate

  • Security services are sold as separate FortiGuard subscription bundles, so ATP, UTP and ENT determine which protections are actually active
  • Throughput is tied to the appliance model, from 500 Mbps on the FortiGate 30G to 520 Gbps on the 7121F, so capacity planning is a hardware purchase
  • Pricing is not published and goes through partners
