My workflow blew up when I started using Claude Code full-time. Suddenly I'm editing Claude and skill files in multiple projects, managing MCP server configs - and running 8-10 agent sessions in different terminal windows.

I'm scattered. I'm checking the wrong tab. I'm missing agent prompts. I'm editing raw markdown soup in VS Code's split preview thinking there has to be another way.

I needed a way to wrangle it all together.

So I built Wrangle - a native Swift macOS markdown editor for the devs and power users of Claude Code.

The short version:

  • Project switching - quickly change contexts between entire workspaces

  • Embedded terminals - run Claude Code, Gemini, whatever in tabbed terminals inside the app

  • Session context - each terminal shows its linked Claude.md, active skills, and MCP servers

  • Embedded browser - manage multiple browser tabs, import bookmarks, and check dev tool panels

  • Smart notifications - agent needs input? Finished a task? Needs permission? You get a native macOS notification that takes you straight to the right terminal tab. This is the feature that keeps me in flow

  • Rendered markdown editing - like Typora, but built for AI config files. XML blocks (`<tools>`, `<instructions>`, `<system>`) get syntax highlighting and collapse

  • Token counting - this is experimental, but shows your rough token usage for that file.

I think it's pretty rad, built in Swift so it's snappy fast. No electron app.

It's $19 one-time. No subscription. Free upgrades. macOS only (Apple Silicon, Sequoia+).

I'm a solo dev. If you don't like it, tell me why - I'm going to keep improving it. Report feedback/bugs here.

If you don't run AI agents daily, Wrangle isn't going to change your life. That's fine - it was built for the power user who has 15 Claude.md files open right now, and just as many Claude Code sessions.

Built with heavy AI assistance; every line of Swift reviewed by a professional Swift dev. A tool for AI-native dev, built the same way.
