What is Meridian by Rynfar?

Meridian lets Pi, OpenCode and other supported coding clients use Claude through the Anthropic Agent SDK, with provider management and a usage dashboard. Antigravity support is available as a preview through Google's signed-in CLI; an optional Mac app provides a desktop interface.

Pros

  • Works with multiple coding clients
  • Local dashboard for provider requests and usage

Cons

  • Requires supported provider sign-in
  • Antigravity integration is still a preview
