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.; Rhombus Systems the per-camera annual licence never ends and a camera without an active licence stops working, so the total cost over a ten-year hardware life is several times the hardware price.
  • They diverge on capability: Helix covers Multiple Selections, Rhombus Systems covers On-camera storage.
  • 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.

Rhombus Systems

  • The per-camera annual licence never ends and a camera without an active licence stops working, so the total cost over a ten-year hardware life is several times the hardware price.
  • Cameras must be Rhombus, so there is no reuse of existing IP cameras and migrating away means replacing every device rather than changing software.
  • Cloud archiving is priced separately by retention and stream count, and long retention on multisensor cameras runs into five figures per camera, which can dwarf everything else in the quote.
  • On-camera storage is the default retention, so a camera physically stolen or destroyed takes its unarchived footage with it unless cloud archiving was paid for on that camera.
  • Analytics and integrations are good for mid-market needs but shallower than a dedicated enterprise VMS with a large third-party ecosystem, so specialist requirements like advanced LPR or forensic search hit limits.

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
Rhombus Systems: Do I need an NVR or a server?

No. Cameras record on board and connect directly to the cloud console, which is the main operational reason organisations pick it.

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
Rhombus Systems: What does the licence cost?

Roughly $149 per camera per year for Professional and about $199 for Enterprise, typically sold in one, three, five or ten year terms.

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
Rhombus Systems: Is cloud storage included?

No. On-camera storage is the default. Cloud archiving is a separate charge priced by retention duration and number of streams.

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
Rhombus Systems: Can I use my existing cameras?

No. The platform works only with Rhombus hardware, which is the trade-off for the zero-server architecture.

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.
