The short version

  • Only Helix has a free tier, so it costs nothing to try first.
  • Each has a real cost: Helix no official GUI application yet, so it requires comfort with terminal workflows.; 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.
  • They diverge on capability: Helix covers Multiple Selections, Signicat covers eID scheme brokering.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

Helix

  • No official GUI application yet, so it requires comfort with terminal workflows.
  • Plugin ecosystem is far smaller than Vim's or Neovim's, limiting customization.
  • Keybindings differ from both Vim and Kakoune, adding a learning curve for users of either.
  • Configuration is more limited than Neovim's Lua-based extensibility.

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

Helix: Is Helix free to use?

Yes, Helix is free and open source, licensed under the Mozilla Public License 2.0 (MPL-2.0), with no paid tiers 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.

Helix: How do I install Helix?

Install via your operating system's package manager, or download pre-built binaries from GitHub Releases; the nightly version requires building from source.

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.

Helix: Does Helix support plugins?

Not yet. Helix currently has no plugin system, though the project intends to add one eventually; it instead ships with built-in LSP and tree-sitter support out of the box.

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.

Helix: How do I configure Helix?

Helix ships with sane modern defaults requiring much less config-file fiddling than Vim, though settings can still be customized in a config.toml file.

Source
Helix: Where can I get help or support?

Support is community-driven via GitHub for code and issues, the Matrix chat for discussion, and OpenCollective for funding ongoing development.
