About Thalia
Thalia is a native SwiftUI Mac app for agentic coding built on Meta's Muse Code CLI. You open a project folder, start a chat per task, have Muse plan the approach before any edit, steer it while it runs, and review the exact diff before approving. It adds checkpoints with rewind previews, worktrees, built-in checks, and a push-and-open-PR flow through the GitHub CLI. It is free to use, requires your own Muse access, and sends the Thalia team no analytics or telemetry.
