Tolgee
In-context localization — Alt+click to translate in your live app.
Apache 2.0 alternative to Crowdin with SDK integrations for React, Vue, and more. AI translation, MCP server for coding assistants, and Docker self-hosting.
Phrase is an enterprise localization platform (formed from the 2022 merger of PhraseApp and Memsource) covering translation management, software localization, and machine translation for large organizations. It's closed source, and enterprise-tier pricing is aimed at companies with substantial, ongoing localization needs.
Tolgee is an open-source localization platform that covers the core translation-management workflow, including in-context editing, without Phrase's enterprise pricing.
