GrowthBook vs Confidence for Claude Code
Verdict
Confidence has the stronger Claude Code integration today: Confidence (5/5: official Anthropic-marketplace plugin with MCP server + 15 skills), versus GrowthBook (4/5: official Anthropic-marketplace plugin with 4 skills (no bundled MCP server)). That doesn’t make it the better product for every team, but your agent will get more official tooling out of the box.
