What real users say: Tolgee vs Cognition AI

Not marketing copy and not our opinion — a structured sweep of public discussion (reviews, forums, communities and video comments), showing what people praise and what they complain about for each tool.

Tolgee

23 mentions across 4 sources · 61% positive — mixed (weighted across 4 sources)

Hacker News, YouTube, Product Hunt, GitHub

What users praise

  • • In-context editing lets non-technical teammates edit live app text without developer involvement
  • • Truly open-source with self-hosting, avoiding the vendor lock-in of Crowdin and Lokalise
  • • AI translator uses UI context, brand voice, and glossaries rather than bare string translation
  • • Broad SDK coverage across React, Vue, Angular, Svelte, Next.js, plus REST, CLI, and MCP server

What frustrates them

  • • Open Vue $t reactivity bug with staticData preloads breaks language switching in production
  • • Cache does not fall back to static data on rejected backend fetches, leaving empty UI
  • • @tolgee/format-icu declares no dependencies despite importing from @tolgee/core in types
  • • 5 open issues in the 7.x SDK line as of late 2026 signal rough release edges
