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; Signicat national eID scheme fees are passed through on top of Signicat's own charge, so a single-country business almost always pays less by integrating with the scheme directly.

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

Signicat

  • National eID scheme fees are passed through on top of Signicat's own charge, so a single-country business almost always pays less by integrating with the scheme directly.
  • Value is concentrated in Northern and Western Europe, and coverage in Southern and Eastern Europe is thinner, so a pan-European rollout still hits gaps requiring document fallback.
  • Pricing is per transaction and quoted, and because scheme rates vary by country the cost per onboarded customer differs materially between markets in ways that complicate unit economics.
  • Each eID scheme connection typically carries its own setup fee and approval process, so adding a country is a project with a lead time rather than a configuration change.
  • Availability is tied to the national schemes, meaning an outage at BankID or MitID stops your onboarding entirely and there is no vendor-side mitigation for it.

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
Signicat: Is this an alternative to a document verification vendor?

Only where national eID exists. In markets with a mature bank ID scheme it is better; elsewhere you fall back to document checks, which Signicat also provides.

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
Signicat: Do we still pay the eID schemes?

Yes. Scheme fees are passed through in addition to Signicat charges. Ask for the split when comparing to a direct integration.

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.

Source
Signicat: Are signatures legally qualified?

Signicat supports eIDAS qualified electronic signatures, which carry the highest legal standing in the EU, as well as advanced signatures.
