Contentrain
Open-source tools for developers. Studio workflows for teams.

Govern the content your AI ships into code.

Contentrain turns hardcoded UI copy, docs, and structured content into a Git-native system that AI agents can safely operate. Start locally with MCP, CLI, and SDK packages; add Studio when teams need review, roles, media, and delivery.

One governed content system

Agent generates. Human approves. Git records every change.

The same structured content contract powers local developer tools and Studio review, so teams can scale without moving content into a separate source of truth.

From hardcoded copy to governed content

Start with the mess already in the codebase.

Most teams do not wake up needing a CMS. They wake up with hardcoded copy, no translation path, and AI agents editing strings directly in source files.
