Answers to common Nimbalyst questions about open source, Claude Code custom commands, multiple workspaces, data privacy, offline use, and file associations.

Quick answers to the questions we hear most often.

Is Nimbalyst open source?

Yes. Nimbalyst is open source and the code lives at github.com/nimbalyst. You can read the source, file issues, and contribute pull requests.

The open source page covers the license and what is included.

Can I use my existing Claude Code custom commands?

Yes. Nimbalyst runs Claude Code itself, so slash commands in .claude/commands/ and the instructions in your CLAUDE.md work the same way they do in the terminal.

Can I have multiple workspaces open?

Yes, you can open as many windows as you like. Each workspace is independent, and you switch between them with the standard window shortcuts.

Is my data sent to AI providers?

When you send a message to an agent, the prompt and the context supplied to that session go to the agent or model provider you selected. Nimbalyst does not send your project files to an AI provider merely because you opened or edited them. API keys you enter in Settings are stored encrypted at rest on your device and are used to authenticate requests to that provider.

With LM Studio, inference runs on the local server you configured. Other app features, such as update checks, sign-in, sync, or optional sharing, may still use the internet independently of the model request. See Privacy for the full data-flow explanation.

Nimbalyst keeps opening my .md files instead of VS Code (or another app)

This is a macOS behavior, not a Nimbalyst issue. On Mac, the "Always Open With" option in the right-click menu only applies to that specific file, not all files of that type.

To change the default app for all .md files:

In Finder, select any .md file
Press ⌘ + I (Get Info)
Under Open with, select your preferred app (e.g., Visual Studio Code)
Click Change All...

This tells macOS to open every .md file with your chosen app going forward.

Can I use Nimbalyst offline?

The full markdown editor works offline. AI features need an internet connection, except LM Studio, which runs locally.

What languages does Nimbalyst support?

English today.

How does Nimbalyst compare to my current tools?

Side-by-side comparisons against editors, task trackers, diagram tools, and agent harnesses are on the comparison pages.
