Not ideal for

Dark Reader

  • People who need a guaranteed perfect dark theme on every site: the README describes it as aiming to reduce eyestrain, and site fixes are not automatically synced by default
  • Firefox users who want it on restricted pages without lowering browser security settings, since the README asks them to change about:config and warns of a security risk
  • Users looking for a system-wide dark mode for their whole operating system; the README only describes browser use

Saladict

  • People who need offline-only use, since the README does not describe an offline mode
  • Users looking for a standalone desktop app, since it is a browser extension
  • Anyone who needs a guaranteed dictionary source, because the README says some dictionaries depend on API keys set in a .env file

Trade-offs

Dark Reader

  • Some pages may not look right, and fixing them can require manual site-fix steps described in the README
  • On some Firefox restricted pages, it needs extra browser settings changes that carry a security risk
  • Automatic site-fix syncing is disabled by default, so users must enable it manually

Saladict

  • The README is truncated and does not list which dictionaries or languages are supported
  • Some dictionaries need API keys configured through a .env file when building from source
  • Building from source requires a Yarn-based toolchain and the README gives no version requirements
