Why KAERIS
For a developer with a locale file and a deadline, not for a localization department.
Who it is for
Lokalise, Crowdin, Lingo.dev and Tolgee are built for teams with translators, reviewers and a localization manager. If that is you, use them. If you have a file, a CI pipeline and no budget for a platform, this is how KAERIS compares.

Where KAERIS is the better fit
You want to try it on your real file in the next two minutes, with no account.
You need a check in CI that fails the build on a broken placeholder or plural, whoever did the translation. It is free and needs no key.
You would rather pay $19 a month, or $79 once, than $66 to $149 a month.
Where it is not
You have human translators who need a web editor, comments and review steps.
You need more than 46 languages, or Figma and CMS integrations.
You need a contract, single sign-on or an SLA.
