Languages

Octa's interface, menus, dialogs, the status bar, the SQL and multi-search panels, the right-click menus, and the Settings dialog (including its hover tooltips), can be shown in any of 31 languages.

Change it under Settings → Appearance → Language. The switch is live: the interface updates on the next frame, with no restart.

Good to know

  • Machine-generated translations. The non-English catalogs are machine-translated and may be refined over time. English is the master; anything not yet translated falls back to the English string rather than showing a blank or a key.
  • What stays in English on purpose. Technical identifiers are not translated, so they read the same in every language: format names (Parquet, JSON, …), database engine names, theme names (Nord, Dracula, …), schema-export targets, and low-level reader error messages.
  • Number formatting is separate. The decimal mark and digit grouping are controlled by Number style (English 1,234.56 vs European 1.234,56) in Settings → Table View, independent of the UI language.

Scripts not yet offered

The interface covers Latin, Greek, Cyrillic, and CJK (Chinese, Japanese, Korean) scripts. Right-to-left scripts (Arabic, Hebrew) are out of scope for the UI: beyond translated catalogs they need layout work that Octa does not do.

This is separate from displaying non-Latin data: Octa bundles a Noto Sans CJK fallback face, so cell values containing Chinese, Japanese, or Korean text render correctly in the table regardless of the UI language. Colour emoji and full right-to-left shaping are not rendered.
