Canto for macOS

Native SwiftUI companion for Claude Code users. Frozen at v1 — maintenance only.

Canto for macOS is a standalone markdown editor designed around Claude Code's file conventions (CLAUDE.md, .claude/memory/*.md, plans). It runs as its own window, outside any IDE.

Status: This is the reference implementation. Active development has moved to the VS Code extension which works inside VS Code, Cursor, Windsurf, and VSCodium.

• VS Code extension (primary product): https://github.com/8infinitelabs/canto
• Landing page: https://canto.infinitelabs.co
• Built by: Infinite Labs OÜ

Why this exists

Before the VS Code extension, Canto was planned as a native macOS app. The SwiftUI implementation reached v1 (sidebar, WYSIWYG editor, memory browser, plans browser, config panel) but the decision was made to ship inside the IDE where Claude Code users already work. This repo keeps the macOS source as a reference and for users who want a standalone window.
