The short version

  • Only Prettier has a free tier, so it costs nothing to try first.
  • Each has a real cost: Prettier inflexible style rules that cannot be customized significantly, forcing teams to accept opinionated defaults; Silent Eight automated disposition has to clear model risk governance and a regulator, and the shadow running period before auto-close is permitted can consume most of the first year of the contract.

Where each one falls short

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

Prettier

  • Inflexible style rules that cannot be customized significantly, forcing teams to accept opinionated defaults
  • Developers must format entire files rather than selective line ranges in some contexts
  • Limited language support compared to some alternatives, though it covers major languages

Silent Eight

  • Automated disposition has to clear model risk governance and a regulator, and the shadow running period before auto-close is permitted can consume most of the first year of the contract.
  • It does not improve detection, so an institution with a poorly tuned monitoring system automates the handling of bad alerts rather than fixing why they exist.
  • Pricing is tied to alert volume, which means efficiency gains elsewhere that reduce alerts also reduce the vendor bill in a way sales teams structure minimums against.
  • The headcount saving is only realised if the institution actually reduces the analyst pool, and many banks redeploy rather than cut, leaving the business case unrealised on paper.
  • As a mid-sized private vendor serving tier one banks, concentration risk cuts both ways; the loss of one large client materially affects the company, and buyers should ask about financial stability during diligence.

Answered from the vendors’ own pages

Prettier: Is Prettier free and open source?

Yes, Prettier is completely free and open source, available as an npm package with no licensing costs or subscriptions.

Source
Silent Eight: Does Silent Eight replace our screening system?

No. It consumes alerts from your existing screening and monitoring systems and decides them. The detection layer stays where it is.

Prettier: Can Prettier be integrated with ESLint?

Yes, Prettier integrates with ESLint by disabling ESLint formatting rules via eslint-config-prettier, allowing both tools to work together with Prettier handling formatting and ESLint handling code quality.

Source
Silent Eight: Will a regulator accept AI closing alerts?

It depends on your jurisdiction and your model governance evidence. Banks typically run extended shadow mode first and phase auto-closure by alert type.

Prettier: Does Prettier support configuration customization?

Prettier is intentionally opinionated with limited configuration options to enforce consistency. You can create a .prettierrc file for basic customization, but Prettier does not support extensive rule customization like ESLint.

Silent Eight: Where is the company based?

Singapore, with offices in New York, London and Warsaw.
