The short version

  • Only ESLint has a free tier, so it costs nothing to try first.
  • Each has a real cost: ESLint slow performance on large codebases compared to newer tools like Oxlint and Biome; MetricStream implementation typically costs one and a half to two and a half times the first year licence, so a one million dollar licence carries a one and a half to two and a half million dollar rollout that rarely appears in the initial business case.

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

MetricStream

  • Implementation typically costs one and a half to two and a half times the first year licence, so a one million dollar licence carries a one and a half to two and a half million dollar rollout that rarely appears in the initial business case.
  • Full deployment takes six to eighteen months, during which the organisation runs old and new processes in parallel and the promised efficiency gain is negative.
  • Per-user pricing in the low thousands per year per seat discourages giving access to the first line of defence, which is precisely where risk data originates, so many deployments end up with data still arriving by spreadsheet.
  • Configuration flexibility comes at the price of specialist skills, and organisations become dependent on MetricStream partners or a small internal team, making later changes slow and expensive.
  • The interface and workflow feel enterprise-heavy next to modern compliance tools, and infrequent business users find it hard, which suppresses the participation the platform is meant to enable.
