The short version

  • Each has a real cost: Neovim no official first-party GUI is shipped; Neovim itself is a terminal-based editor and only maintains a curated list of third-party GUI front-ends; Userscripts safari cannot let extensions bypass a site's Content Security Policy, so strict sites produce "Refused to execute a script" errors that the @inject-into workaround does not always fix.
  • They diverge on capability: Neovim covers Async job control, Userscripts covers Built-in script editor.
  • Prices and features above were last checked on 17 September 2026.

Where each one falls short

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

Neovim

  • No official first-party GUI is shipped; Neovim itself is a terminal-based editor and only maintains a curated list of third-party GUI front-ends
  • Licensing is not uniform: code contributed after commit b17d96 is Apache 2.0, but code carried over from Vim (tagged vim-patch) remains under Vim's own license
  • Built-in LSP client and Tree-sitter integration are frameworks requiring separate configuration or plugins for language servers/grammars to be useful, not out-of-box language support
  • No official iOS, Android, or web build

Userscripts

  • Safari cannot let extensions bypass a site's Content Security Policy, so strict sites produce "Refused to execute a script" errors that the @inject-into workaround does not always fix.
  • Apple only. There is no Chrome, Firefox or Edge build, so it cannot be a cross-browser answer.
  • iCloud sync is documented as having delays, which is awkward when editing the same script on two devices.
  • Requires macOS 12 and Safari 14.1, or iOS 15.1, so older Apple hardware is excluded.
  • GPL v3 means a commercial licence is required for non-open-source use, which matters if you are embedding rather than just using it.

Answered from the vendors’ own pages

Neovim: How much does Neovim cost?

Neovim is free and open-source software. No cost is associated with downloading, using, or distributing Neovim. The project is community-driven with optional sponsorship opportunities for those who wish to support its development.

Source
Userscripts: Is Userscripts for Safari free?

Yes, free on the App Store and licensed under GPL v3. A commercial licence is required for use in something that is not itself open source.

Source
Neovim: Is Neovim open source?

Yes, Neovim is free, open-source software available to everyone at no cost. Users can download, modify, and distribute it freely for any purpose.

Source
Userscripts: Does it work on iPhone?

Yes, on iOS and iPadOS 15.1 or later, which makes it one of the few ways to run userscripts on an iPhone.

Source
Userscripts: Why do I get "Refused to execute a script" errors?

Safari does not let extensions bypass a site's Content Security Policy the way other browsers do. The documented workaround is changing the script's @inject-into setting, though it does not resolve every case.

Source
Userscripts: Do my scripts sync between Mac and iPhone?

Yes, over iCloud, though the project notes the sync can be delayed rather than immediate.

Source
Userscripts: What are the system requirements?

macOS 12 or later with Safari 14.1 or later, or iOS and iPadOS 15.1 or later.
