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.; Yoti age estimation returns a probabilistic range rather than a verified date of birth, so it only works with a safety buffer above the legal threshold and cannot prove an exact age.
  • They diverge on capability: Helix covers Multiple Selections, Yoti covers Facial age estimation.
  • 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.

Yoti

  • Age estimation returns a probabilistic range rather than a verified date of birth, so it only works with a safety buffer above the legal threshold and cannot prove an exact age.
  • Estimation accuracy varies by demographic and reported error margins widen at the age bands that matter most for eighteen-year thresholds, which pushes borderline users into a document fallback you still have to pay for.
  • Pricing is not published, so buyers cannot compare the cost of an estimation check against a document check without going through sales.
  • Regulatory acceptance of facial estimation differs by jurisdiction, so a method that satisfies Ofcom may not satisfy a regulator elsewhere and multi-market platforms need more than one approach.
  • The reusable digital identity app depends on consumer adoption, which is meaningful in the UK and thin elsewhere, limiting the reusability benefit outside its home market.

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
Yoti: Does age estimation store my face?

The image is used to produce an estimate and then deleted rather than retained, which is the specific property that makes it usable for age assurance on minors.

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
Yoti: Is it accepted for UK Online Safety Act compliance?

Facial age estimation is one of the methods regulators have accepted as highly effective age assurance. Confirm the current position with your own counsel for your content category.

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
Yoti: Can it prove someone is exactly 21?

No. It gives a range. If you need a precise age you need a document or database check, which Yoti also sells.

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.
