Messagevisor
Translation as code for product teams
Messagevisor is an open source, Git-native toolkit for i18n and l10n. Author messages, locales, and audience-targeted overrides as version-controlled definitions in your repo. Lint and test translations in CI, then build compact JSON datafiles your app consumes via a small SDK. No vendor TMS, no lock-in. Supports ICU formatting, RTL, regional locale inheritance, multi-environment promotion, and CSV/AI translator handoff. Works with React, Vue, Next.js, and more. MIT licensed, free forever.
Hi there, creator of Messagevisor here. I started this project continuing my journey of building Git-based authoring tools (like Featurevisor before for feature management), and this time tackling the area of i18n and l10n.
Times are changing, and I believe in today's agentic world (with Claude Code, Codex, Cursor), developer tools paired up with skills and commands can help bring more traditionally non-technical workflows into Git.
Let me know if you give it a try!
