The short version

  • Only Helix has a free tier, so it costs nothing to try first.
  • Each has a real cost: Fenergo implementations commonly run twelve to twenty-four months and depend on a systems integrator, so the services cost frequently exceeds the software subscription in year one.; Helix no official GUI application yet, so it requires comfort with terminal workflows.
  • They diverge on capability: Fenergo covers Regulatory rules library, Helix covers Multiple Selections.
  • 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.

Fenergo

  • Implementations commonly run twelve to twenty-four months and depend on a systems integrator, so the services cost frequently exceeds the software subscription in year one.
  • It orchestrates screening but does not supply the sanctions, PEP or adverse media data, so you still buy Dow Jones, LexisNexis or World-Check separately and those fees are per screened entity.
  • The entry price is set for institutions with large onboarding volumes, which puts it out of reach of smaller banks and fintechs that would otherwise benefit from the rules library.
  • Configuration is deep and specific, which makes upgrades between major versions a project rather than a patch, and some customers stay on old releases for years.
  • The rules library covers regulatory requirements, not your internal risk appetite, so the policy tuning that determines whether onboarding actually gets faster remains your work.

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.

Answered from the vendors’ own pages

Fenergo: Does Fenergo do the sanctions screening itself?

No. It orchestrates calls to third-party data providers such as Dow Jones and World-Check, and those subscriptions are additional and usually charged per screened entity.

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
Fenergo: Is it SaaS or on-premises?

Both. The SaaS offering runs on Microsoft Azure with regional deployment options, which matters where data residency rules prohibit client data leaving the jurisdiction.

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
Fenergo: How long does a deployment take?

Plan for a year at minimum for a multi-jurisdiction rollout. Single-jurisdiction deployments with a narrow product set can be shorter but rarely under six months.

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
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.
