Run multiple coding agents in parallel, edit their work visually in markdown, mockups, and diagrams, and track tasks. Free, MIT-licensed desktop app for macOS, Windows, Linux, with mobile companion for iOS and Android.
No outside reports on file
Use Nimbalyst only on projects you trust and review all AI-generated code carefully before accepting changes; the parallel-agent setup makes it easy to miss unexpected modifications.

About Nimbalyst
Nimbalyst is a desktop workspace that lets you run multiple AI coding agents (like Claude Code or Codex) at the same time and see their work visually. You can edit their code, mockups, and diagrams in one place and track tasks across projects.
Who it’s for
Developers who want to experiment with running several AI coding assistants together and need a visual way to manage and compare their outputs. Teams exploring parallel coding agent workflows.
Alternatives
- Continue Dev (VS Code extension for managing multiple AI agents)
- GitHub Copilot Workspace (GitHub's native multi-agent coding interface)
- Cursor (AI code editor with built-in agent features)
- OpenAI Code Interpreter (run code and agents in a single notebook-like environment)
Setup
Check these steps against the project’s own instructions before running anything.
Follow the project's README. The tool is available as a desktop app for macOS, Windows, and Linux; visit the GitHub repository for download and installation instructions specific to your system.

Security reports
No reports found for this package in our research (last checked 2026-10-29).
Risks to watch for
- Local file access: The app likely reads and writes files in your project directories, so any agent it runs could access or modify code you don't intend to share.
- Agent output risk: Multiple agents working in parallel could produce conflicting or malicious code changes if not carefully monitored; visual editing doesn't guarantee safety.
- Plugin or extension risk: If the workspace supports plugins or extensions, malicious ones could intercept AI outputs or steal code before you see it.
- Mobile companion: The iOS and Android companion apps may sync data to servers; unclear what privacy controls exist or how data is stored.
- Prompt injection: AI agents could be tricked by hidden instructions in code files or diagrams you import, leading to unexpected behavior.
How to lower the risk
Least-privilege permissions
- Run the app only on code repositories you control and understand.
- Disable or sandbox any agent plugins you don't actively use.
Network isolation
- Check if the mobile companion requires cloud sync; consider disabling it if you work with sensitive code.
- Monitor outbound network traffic to see what data leaves your machine.
Monitoring
- Review file changes after each agent run; use git diff to spot unwanted modifications.
- Keep logs of which agents modified which files and when.
Red flags to watch for
- Agents making changes without your explicit request or making changes to unrelated files.
- Slow performance or unexpected network activity when no sync is expected.
