The short version

  • Each has a real cost: Helix no official GUI application yet, so it requires comfort with terminal workflows.; Selenium flaky tests are the standing complaint: explicit waits and synchronisation are the tester’s job, where newer tools handle it automatically
  • They diverge on capability: Helix covers Multiple Selections, Selenium covers W3C WebDriver.
  • Prices and features above were last checked on 29 August 2026.

What people use each for

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.

Selenium

  • Flaky tests are the standing complaint: explicit waits and synchronisation are the tester’s job, where newer tools handle it automatically
  • Setup involves drivers, versions and grid infrastructure that Playwright and Cypress bundle away
  • Slower to run than tools that talk to browsers over a debugging protocol rather than WebDriver

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
Selenium: Is Selenium free?

Yes, open source with no licence fee. Paid costs come from grid infrastructure or services like BrowserStack.

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
Selenium: Selenium or Playwright?

Playwright handles waiting automatically and is faster to set up, which removes most flakiness complaints. Selenium wins on language breadth, browser coverage including Safari, and existing suites you already have.

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
Selenium: Is Selenium still relevant?

Yes. Its WebDriver protocol is a W3C standard implemented by every major browser, and very large existing suites are not rewritten cheaply.

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.
